JAPANESE MINKA CII - INTERIORS 43: ENTRY AREAS 2

The о̄-do-guchi entry (大戸口, lit. ‘big door mouth’), which corresponds to the everyday entry and exit, is a robust о̄-do (大戸 ‘big door’), usually sliding, of about one ken (1.81m) in width. Because these doors are heavy and inconvenient to open and close, they were left open during the day, when the entrance was covered with a light ‘high-waist shо̄ji’ (koshi-daka shо̄ji 腰高障子), a sliding door consisting of a boarded lower half and papered lattice upper half. For entry and exit at night when the о̄-do was drawn over the opening, there was the moguri (潜り, lit. ‘diver’), a ‘door within a door’ installed in part of the о̄-do. The image below shows such an arrangement: during the day, the two koshi-daka shо̄ji are drawn over the opening; at night they are drawn back, and the о̄-do is drawn. The unusually high sill on this moguri, requiring one to ‘straddle enter’ (mataide-hairu 跨いで入る), is an old style, intended to discourage uninvited intrusion. Additionally, around the mid rail of the moguri, on the о̄-do side, there is a kururu (くるる) locking mechanism consisting of a small top-hung block and latch that prevents the moguri door from being opened. The horizontal battens on the left, attached to the face of the wall flanking the entrance (to-guchi 戸口), form a ‘scratch climb’ (kaki-nobori 掻き上り) ladder (hashigo 梯子) that leads to the servants’ room (shiyou-jin shitsu 使用人室) above the shimo-mise (しもみせ ‘lower shop’) that lies beyond the wall and door at the far left of the image.

Detail (shо̄sai 詳細) drawings of an о̄-do (大戸) and moguri with a simple but secure door locking (to-jimari 戸締り) mechanism. Here the sliding (hiki-do 引き戸) boarded (ita-do 板戸) moguri is called the kuguri-itado (くぐり板戸), kuguri (くぐり), or koguri (こぐり). The lock itself is called the kururu (くるる) or age-otoshi-saru (上げ落し猿, ‘raise drop monkey’) and is made from zelkova (keyaki けやき, Zelkova serrata), a hardwood. The kururu consists of two operable parts: a timber block or ‘latch’, 18cm long, and a timber ‘bolt’ of the same length. The block is top-hinged to, and fits exactly between, two vertical members of the о̄-do. When the block hangs vertically, it is recessed into the о̄-do so that the kuguri can slide freely past it into the open position. The bolt is connected to the bottom edge of the block by two timber pegs that run through longitudinal slots on the bolt, so that the bolt is restrained up-down but free to move laterally (left-right). To lock the door, the kuguri is closed, and the bottom of the block is swung up so that it obstructs the path of the moguri, with its right edge in contact with the side of the moguri’s left vertical frame member or ‘stile’. To prevent the block from falling back to its vertical ‘open’ position when let go of, the bolt is slid across to the right so it rests against the face of the moguri’s left stile.

The image below shows the house of a village headman in Shiojiri (塩尻), Nagano Prefecture. It also has a genkan-gamae, but this one features a papered shо̄ji moguri in the о̄-do-guchi. The moguri-do (潜り戸, lit. ‘diving door’ or ‘ducking door’) has three handles or ‘pulls’ (hikite 引手) whose use is not determined according to whether one is a man, woman, or child, but by one’s feudal class status: the upper pull is for the landlord class (jinushi kaikyū 地主階級), the middle for farmers who owned and worked their own land, called takamochi byakushо̄ (高持百姓, ‘high hold commoner’) or ji-sakunо̄ (自作農, lit. ‘self make farming’), and the lower for tenant farmers (ko-sakunо̄ 小作農, lit. ‘small make farming’), day labourers and the like, called mizunomi byakushо̄ (水呑み百姓, lit. ‘water drinking commoner’). The lowest pull is the dirtiest, indicating that it was the most used.

The utilitarian entrance door (о̄-do 大戸) is on the left, and to its right is the formal genkan entrance, with board floor (shiki-dai 式台), opaque timber lattice panels (maira-do 舞良戸) and papered timber lattice sliding panels (shо̄ji 障子). To the right of the genkan, extending perpendicularly out from the facade, are the garden wall and garden gate (niwa-chūmon 庭中門), on the other side of which is the guest room (kami-zashiki 上座敷) which faces onto the garden (tei-en 庭園). This arrangement is representative of mid-scale farmhouses (chū-nо̄-ka 中農家) in the Kinki region.

In Yamato (大和) and part of Kawachi (河内), there are areas in which one ken wide (1.81m) sliding shо̄ji, for daytime use, are installed on the exterior side of the о̄-do, as in image below. Though these double-wide shо̄ji are somewhat heavy and cumbersome to operate (traditional Japanese sliding fittings do not have rollers or wheels but simply slide in tracks cut into the sills, though the tracks can be waxed to reduce friction and wear), they are sturdy, and from a security standpoint there are favourable aspects to a door that cannot be opened easily.

In places like the islands of Amami (奄美) and Hachijou (八丈), where the raised-floor style (taka-yuka keishiki 高床形式) houses have no earth-floored utility area (doma 土間), the exterior ‘verandah’ (gai-en 縁) becomes the entrance, and footwear is kept under it, or in the shelter of the ‘windbreak’ (kaze-yoke) 風除け where the gai-en turns a corner. In more recent times, however, you could also find houses of this type with a simple kind of genkan-gamae, where part of the under-eaves space (geya 下屋) was made into a doma, and equipped with a shо̄ji door (shо̄ji-do 障子戸) of vertical-batten construction (tate-zan-gumi 竪桟組), called a kо̄shi-do (格子戸, ‘lattice door’). Kо̄shi, more commonly encountered as the characteristic vertical timber ‘grilles’ fixed over the facade windows of townhouses (machiya 町家), are of more robust construction and more closely spaced than the latticework of shо̄ji, and are intended to provide security and some privacy to the people and goods within. Kо̄shi-do style (kо̄shi-do keishiki 格子戸形式) doors are common at the entrances of machiya in all Japan’s regions, but о̄-do with moguri are also used. Machiya as a rule have narrow frontages, so instead of a single-leaf sliding (kata-biki 片引き) door that requires the room behind it to be double its width for it to fully open, it is common to find top-hung doors that are swung inward and upward and held open on iron hooks suspended from the ceiling, or side-hung hinged (chо̄-tsugai-dzuri or chо̄-ban-dzuri蝶番吊り) doors that swing inwards against the side wall.

JAPANESE MINKA CI - INTERIORS 42: ENTRY AREAS 1

In this and the next few posts, we will consider the various types of entry and exit (de-iri-guchi 出入口, lit. ‘out in mouth’) found in minka, beginning here with an examination of the formal entry (seishiki iri-guchi 正式入口), the genkan (玄 関, lit. ‘dark/mysterious gate’).

In the typical minka, there are two principal entry points: the doorway (toguchi 戸口, lit. ‘door mouth’) to the earth-floored utility area (doma 土間) for everyday (ke ケ) use, called the о̄-doguchi (大戸口, ‘big doorway’), tonbo-guchi (とんぼ口), or tobo-guchi とぼ口); and the entry at the front of the formal room (zashiki 座敷) from the ‘verandah’ (engawa 縁側), which serves as the formal (hare ハレ) entry and exit (de-iri 出入) to the zashiki for ‘public’ (kо̄shiki 公式) guests and visitors. Large, formal genkan settings were only permitted to designated inns (honjin 本陣) and the residences of village heads, doctors, and the like; in other words, places which could expect to receive important visitors or guests. In such residences, there were areas and rooms, such as the ‘upper zashiki’ (kami-zashiki 上座敷 or jо̄dan zashiki 上段座敷) and ‘lower zashiki’ (shimo-zashiki 下座敷), that were exclusively for guests, and it was normal to establish a genkan zashiki (玄関座敷), a formal, tatami-floored entry room, between the guest part of the building and the everyday residential part for the family.

At the front part of the genkan-zashiki is a projecting structure, equivalent to the western porch or portico, that allowed palanquins (kago 輿) to pull up out of the weather. This projection is called the genkan-gamae (玄関構え, lit. ‘genkan structure’) or о̄-genkan or dai-genkan (大玄関, lit. ‘big genkan’). In the somewhat formal houses of middle-class farming families, the semi-formal room known as the dei (でい or 出居) corresponded to the genkan-zashiki, and the engawa in front of it, consisting of a low, boarded shiki-dai (式台 lit. ‘formal/ceremonial platform’), functioned as the formal entrance.

With its board platform floor (shiki-dai 式台), maira-do (舞良戸) panels, ‘rainbow beam’ (kо̄ryо̄ 虹梁) and other elements, this example is furnished with all the components of the standard or ‘classical’ genkan-kamae. Oku family (Oku-ke 奥家) residence, an Important Cultural Property, О̄saka Prefecture.

An underslung palanquin (kago 輿), carried on the shoulders.

A palanquin (kago 輿) carried ‘wheelbarrow style’, with ropes attached to the rails slung around the shoulders.

The genkan-gamae is built projecting perpendicularly out from the main structure; given its functional relationships it is often located more or less at the centre of the façade, and to the right (kami-te 上手) of the every day entrance (toguchi 戸口). Its roof is gabled (kiri-tsuma 切妻) or more commonly hipped-and-gabled/Dutch gabled (iri-moya 入母屋). There is a general intent to give the genkan-kamae roof an expression of formality and dignity, with gable (hafu 破風) designs such as the compound-curved kara-hafu (唐破風 ‘Tang gable’) and the dormer gable (chidori-hafu 千鳥破風, ‘plover hafu’).

The entry of a Buddhist temple building with a ‘Tang gable’ (kara-hafu 唐破風) and other elements that were adopted in minka of affluent families: the gable board pendant (gegyo 懸魚), ‘rainbow beams’ (kо̄ryо̄ 虹梁), ornamental blocks (kaeru-mata 蟇股 or 蛙股), and complex post to beam structural transitions.

Illustration of the difference between a Dutch gable (iri-moya-hafu 入母屋破風), left, and a ‘dormer gable’ or ‘plover gable’ (chidori-hafu 千鳥破風), right.

Often the genkan-gamae was ornamented and beautified in the manner of temple and shrine architecture: moulded surfaces (kuri-kata men 繰型面) or carvings (chо̄koku 彫刻) on the two outer posts and the ‘rainbow beam’ (kо̄ryо̄ 虹梁) that spans them, ‘block and arm’ structural assemblies (斗拱 tokyо̄) taken from Buddhist temple architecture, carved kaeru-mata (蟇股 or 蛙股, ‘frog/toad crotch’) beam blocks, and hanging ‘pendants’ (gegyo (懸魚) added to the bargeboards (hafu-ita 破風板).

The load from the ridge beam is transferred via a block-and-arm (斗拱 tokyо̄) assembly to a robust, solid kaeru-mata (蟇股), then to the ‘rainbow beam' (kо̄ryо̄ 虹梁), and from there to the columns.

The projecting genkan-gamae is about two ken (間) in width, around 3.6m, and one ken deep, around 1..8m. The floor of the outer metre or so is a low, boarded shiki-dai, and at the agari-guchi (上り口, lit. ‘ascend door’) to the genkan zashiki there is a fumi-dan (踏段, lit. ‘tread step’) of wide, thick boards. The exterior entrance opening customarily holds four maira-do (舞良戸) panels, which are fittings (tategu 建具) constructed of a perimeter frame infilled with thin boards and reinforced with battens (san 桟) or ‘muntins’ called maira-ko (舞良子). The outer two maira-do are fixed, the inner two sliding, and behind these on the interior side are two sliding paper-clad shо̄ji (障子) fittings.

The image below shows the house of a wealthy farming family in Tochigi Prefecture. The building has a three-part entry structure: to the right (kami-te 上手) is an о̄-genkan or dai-genkan (大玄関) with a gabled roof layered over a kara-hafu; at the centre is a convex gabled (mukuri-hafu zukuri 起り破風造り) ‘middle genkan’ (naka-genkan 中玄関) for the use of family and relatives (kazoku shinseki 家族親戚) and others; there is also at left (shimo-te 下手), outside the frame of the photograph, an о̄-doguchi (大戸口) entrance for servants (shiyо̄-jin 使用人) and lower-status people and menials (genin 下人, lit. ‘lower people’). On the far side of the о̄-genkan (the genkan-kamae) is a kami-zashiki surrounded by a rinsen (林泉), a garden composed of woods (hayashi 林) and ponds (sensui 泉水); on the near side of the genkan are the family’s residential rooms (kyojū-shitsu 居住室).

The picture below shows the genkan of the house of a village headman (shо̄ya 庄屋) in Kawachi (河内). It has a width of two ken, but has been built without the characteristic projection; instead it is contained within the perimeter of the main volume of the building, by extending (fuki-kudashita 葺き下した) the geya eave (geya-bisashi 下屋庇). Nor are there any maira-do; at night the sliding board partitions (ita-do 板戸) are drawn out from the plastered (nuri-gome 塗りごめ) shutter box (tobukuro 戸袋), on the left, and closed up. In the Kinai (機内) region, the area of western Honshū centred around Kyо̄to and О̄saka, there are, with the exception of very large houses, many such modest genkan, though you can see sophisticated sukiya-style design elements such as the the paving stones (nobe-dan 延べ段) of the path (通路).

JAPANESE MINKA C - INTERIORS 41: TOILETS 3

Both toilet pan fixtures (ben-ki 便器) and urinal fixtures (shо̄ben-ki 小便器) in minka were made from either timber or porcelain. Porcelain fixtures only became widespread in the Meiji period, fired in the kilns of Seto (瀬戸), Tokoname (常滑), and the Takamatsu (高松) area. They were painted with peony (botan 牡丹) or other floral designs; the Sanuki-benki (讃岐便器) of Takamatsu were particularly famous.

Timber urinals were generally box-shaped (hako-gata 箱型) or ‘funnel’ (jо̄go 上戸 or 漏戸) shaped. To lessen sound and smell and prevent splashback, fresh Japanese cypress (sugi 杉, Cryptomeria japonica) boughs were sometimes laid in them; in some areas urinals themselves were called sugi-ya (杉屋 ‘sugi hut’) and sugi no ha (杉の葉 ‘sugi leaves’).

Porcelain urinals developed out of their timber predecessors, with styles such as the ‘morning glory’ (asagao 朝顔, Ipomoea nil), and mukо̄-daka (向高, lit. ‘opposite high’), modelled on a timber stave bucket with lower staves on one side and higher staves on the other.

At their simplest, toilet pans were just holes in the floor, with a vertical timber ‘splashback’ called a mae-tate (前立て ‘front standing’) in front of the hole, and a timber lid (futa 蓋). The mae-tate was also called kin-kakushi (きんかくし, lit. ‘ball (testicle) hider’). It not only clearly demarcates the toilet space into front and back, but also provides something for users, especially infants, to hold onto, and contains ‘overshoot’. The name kin-kakushi suggests that it was intended for men, but among toilet-makers there are those who say that it is women who are the ‘splash-prone’ (hisan no о̄i 飛散の多い) sex, and that the mae-tate is for them. Porcelain toilet pans were known as shimo-hako (下箱 ‘lower box’), and like porcelain urinals, were often ‘ceramicised’ versions of earlier timber forms.

In the upper formal rooms (kami-zashiki 上座敷) of the dwellings of upper-class farmers and officials, an ‘upper toilet’ (kami-benjo or ue/uwa-benjo 上便所), accessed via an associated ‘verandah’ (en), was provided. The most sumptuous of these were called dai-benjo (大便所, ‘big/great toilet’), tatami-laid rooms of around two jо̄ (帖), roughly 3.3m2, in area, some with lacquered (urushi-nuri 漆塗り) timber pans. Even in kami-benjo not appointed to this degree, the floor might be a single board of camphor (kusunoki 楠, Camphora officinarum) wood, and the pan fitted with a lid to prevent odour from rising and competing with the fragrance of the camphor. The urinal could be similarly luxuriously appointed, with for example a smoked bamboo (susu-take 煤竹 lit. ‘soot bamboo’) grating around the base of the fixture. In these kami-benjo and in the toilets of townhouses (machiya 町家), a ‘fertiliser pot’ (koe-tsubo 肥壷) called a gesu-game (下須甕), like an enlarged earthenware mortar (suri-bachi 摺鉢), was set into the ground under the pan. Urban ‘night soil’ was collected and sold as fertiliser to farmers, with the waste of higher-class households, with their more nutritious diets, said to command higher prices.

In remote areas, one could still see in the 20th century large wooden boxes filled with leaves placed in front of toilet pans. While urban areas were a different story, in the countryside it was the norm right up to the Taisho era (Taishо̄ jidai 大正時代, 1912 - 1926) to use leaves and rice straw, either chopped or scrunched up, to wipe. This material was called otoshi-wara (落し藁, ‘dropping straw’). Alternatively, wood scraps (moku-hen 木片) somewhat like disposable chopsticks (wari-bashi 割り箸) were used. There was an old adage that if one saw chopsticks washed up in the shade of a rock in a river valley, one knew that there were people living upstream, but given that chopsticks were not disposable nor thrown away in great numbers in those days, it is likely that the ‘chopsticks’ referred to here were not chopsticks at all, but kuso-bera (糞ベラ or 糞箆, lit. ‘shit spatula’) called chūgi (籌木 or ちゅう木, lit. ‘skewer wood’) or sute-gi (捨て木, lit. ‘throw away wood’), washed down the river.

JAPANESE MINKA XCIX - INTERIORS 40: TOILETS 2

In Hida (飛騨), now northern Gifu Prefecture, there were detached ‘outhouse’ (bettо̄-benjo (別棟便所, lit. ‘separate ridge toilet’) toilets called henchiya (へんちや), in which a large tub (о̄-oke 大桶) of around two metres in diameter is half-buried and secured with red clay around its perimeter, with two boards called ‘pot boards’ (tsubo-ita 壷板) spanning the opening; these toilets were big enough that multiple people could relieve themselves at the same time.

Toilets in the Totsukawa (十津川) area of Nara Prefecture and elsewhere are of the same type, and though their tubs are smaller than those of Hida henchiya, it can be seen from the image below that their use at night by those unfamiliar with them could be perilous.

The interior of an outhouse (bettо̄-benjo (別棟便所), consisting of a half-buried large tub (о̄-oke 大桶) spanned by two boards. Ibaraki Prefecture.

There are regions, like Hida, where the toilet is located in a separate structure, called the seya (背屋 ‘back hut’) or to (外 ‘outside’), and there are many regions where the toilet is attached to the south side of the house, for fertiliser-related reasons discussed in the previous series of posts on minka bathrooms. There are also places where the toilet is located near the rear entrance or ‘back door’ (sedo-guchi 背戸口), under the eaves (noki-shita 軒下), or at one end of a storage building (naya 納屋) or gatehouse (nagaya-mon 長屋門).

A urinal (shо̄-benjo 小便所) was often installed beside the main entrance (to-guchi 戸口), with a low wall (sode-gaki 袖垣) built next to it to provide some privacy. This location was most likely chosen for convenience, in consideration for high-frequency use and nocturnal visits, but there may also have been the motive of relieving visitors of their load of urine for use as fertiliser on one’s own fields.

In cold regions, the urinal would be put inside, in a corner of the earth-floored utility area (doma 土間) or beside the stable (umaya 厩), where human waste products and livestock excreta alike were used as fertiliser. There were also regions where people relieved themselves into tawara (俵), straw ‘barrels’ usually used for storing rice and other consumables. Tawara containing ash and chopped straw (kiri-wara 切藁) were kept in a corner of the doma; in spring the filled tawara were used as compost (taihi 堆肥 ‘pile manure’). These toilets were called shonbe-suma (しょんべすま, perhaps ‘urine corner’) or aku-ba (あくば, perhaps ‘scum place’).

JAPANESE MINKA XCVIII - INTERIORS 39: TOILETS 1

There were three main types of toilet (benjo 便所, lit. ‘excreta place’ or ‘evacuation place’) in pre-modern Japan: the wet or flush type (suisen-shiki 水洗式), the dry type (kan-shiki 乾式), and the ‘retaining’ type (choryū-shiki 貯留式).

Though rare, there could be found in mountainous areas until recent times the ‘prototype wet type’ (genshi suisen-shiki 原始水洗式) toilet, in which the water from a spring-fed pipe (kakehi 筧) was used to flush waste ‘down the valley’, but because human waste (fun-nyо̄ 糞尿, lit. ‘faeces-urine’) was used as fertiliser in farming villages, the overwhelming majority of minka toilets were of the ‘retaining’ or ‘retain and ladle’ type (choryū-kumitori-shiki 貯留汲取り式).

Though not found in minka, an example of the dry-type toilet is the ‘sand toilet’ (suna-secchin 砂雪隠). In this type, the waste is ‘laid’ directly on a floor of pebbles or sand, sprinkled with sand, and taken away to be buried elsewhere. The suna-secchin is closely associated with the tea ceremony (chaseki 茶席), where it eventually became a purely ornamental feature of the inner tea garden, with the actual functional toilet being in the outer garden.

Labelled are the door (?ki-to,？木戸), stone door sill (to-zuri-ishi 戸すり石), windows (mado 窓), sand (suna 砂), ‘dust hole’ (chiri-ana ちり穴), the left foot stone (ashi-kake-ishi 足かけ石, lit. ‘foot place stone’), right foot stone (mae-ishi 前石, lit. ‘front stone’), ‘urine use stop’ (shо̄yо̄-kaeshi 小用返し) stone, and ‘rear stop’ (ura-gaeshi うら返し) stone. The structure is two tatami mats in area.

The name secchin (雪隠, lit. ‘snow hide’), alternatively senchi or senchin, is said to have originated in Buddhist temples. Toilets at Zen temples are called either seijо̄/seijin/seichin (西浄 ‘west clean’), by association with the seijо̄, the place where meditation practice, training, or rites are conducted, or tо̄su (東司 ‘east official’), by association with the tо̄su, the entrance to the seijо̄. Other names for the toilet used at temples include ryūsoku (流廁 ‘flow toilet’) and soku-in (廁院 ‘toilet institution’).

Names for the wet-type toilet include kawaya (廁), which derives from the meanings ‘river hut’ (kawa-ya 川屋) or ‘side hut’ (kawa-ya 側屋), a reminder of when people would relieve themselves in huts built over bodies of flowing water (ryūsui 流水), a method which tended to be more common in the southern areas of the country.

This sophisticated toilet is something of a hybrid: it is a kawaya in the sense that is a ‘drop style’ toilet, though unlike a true kawaya it is not built over flowing water; it is also a suna-secchin toilet, in the sense that the ‘deposit’ is made on sand, though here the sand bed is portable, as as seen in the following photograph.

In the Hokuriku region there are the names kanjo or kanze, which have been interpreted to mean ‘free time place’ or ‘relaxing place’ (kanjo 閑所, lit. ‘leisure place’), although it has also been claimed that they probably derive instead from the Chinese guàn chǔ (灌処, lit. ‘irrigation processing’). Other names of a euphemistic nature include te-arai (手洗い ‘hand washing’), chо̄zu (手水 ‘hand water’) or chо̄zuba (手水場 ‘hand water place’), shian-jo (思案所 ‘contemplating place’), and bunbetsu-jo (分別所 ‘separate place’).

In the Kinki region, there is the slang name kо̄ya-san (高野山, ‘Mount Kо̄ya’ - the home of Shingon Buddhism, in Wakayama Prefecture), which is a pun on the meaning ‘dropping paper/hair’ (kami wo otosu 紙/髪を落とす). Many other dialect names for the toilet exist, including kо̄ka (後架, ‘after frame’), go-fujо̄ (御不浄 ‘honourable unclean’), habakari (はばかり ‘modesty/discretion’), go-yо̄ba (御用場 ‘honourable use place’), and ike-game (埋甕 ‘fill up pot’).

JAPANESE MINKA XCVII - INTERIORS 38: BATHING AREAS 5

In the О̄mi (近江) district, current-day Shiga Prefecture, there were many different styles of bathing, including one called mugi-buro (むぎぶろ), which was common in the peasant houses of the Kotо̄ Heiya (湖東平野), the plain east of Lake Biwa. Mugi (むぎ) is the Japanese word for barley, so the name may be in reference to the shape of a barley grain, or perhaps mugi is a dialect variant of mushi (蒸), ‘steam’. In the illustration shown below, a low stove (kamado 釜土) is fitted with a shallow, plate-like iron kettle (kama 釜), and on this rides the tub (yu-daru 湯樽 or yu-uke 湯桶). The joint is are packed with Japanese cypress (hinoki 桧, Chamaecyparis obtusa) bark and bedded down with plaster (shikkui 漆喰). The barrel is fitted with a door of around 50cm x 70cm in size, with a glazed viewing window. A duck board (fumi-ita 踏板 lit. ‘tread board’) is placed in or over the kama at the bottom of the tub. When closing the door and pouring hot water over oneself, the inside of the tub is sealed off, and the bath becomes a kind of steam bath.

A mugi-buro (むぎぶろ). The water level in the tub (yokusо̄-nai sui-i 浴槽内水位) can only be as high as the door sill, so the water level is very shallow (15 - 18cm). Labelled are the ‘washing place’ (arai-ba 洗い場), clay (nendo 粘土) stove, (kamado かまど) stove mouth (taki-guchi 焚口), cypress (sugi 杉) tub (yu-daru 湯樽), and bamboo hoops (take no taga 竹のたが). Shiga Prefecture.

A mugi-buro or oke-buro (桶風呂) in use. Labelled are the ‘steam’ (jо̄ki 蒸気), hot water (yu 湯), ‘bottom board’ (soko-ita 底板), ‘flat kettle’ (hira-gama 平釜), fire (hi 火), and stove (kamado カマド).

In the area north of Lake Biwa, there is a common type of bath in which the tub is low, but the lid over it can be opened and closed freely with a thin bamboo pole, effectively ‘sealing’ the tub. In this type of bath, too, the water level is shallow, as the tubs can only be filled up to the lower edge of the door opening.

This bath is also a type of mugi-buro, but not as closely sealed as the previous example. After opening the hinged door at the front and entering the tub, one operates the thin bamboo stick propping up the lid to close it. Uemi family (Uemi-ke 上見家) residence, Shiga Prefecture.

A lacquered (urushi-nuri 漆塗り) bathtub (yu-uke 湯桶). Because lacquer would be damaged by the heat of a stove-type or attached-firebox system, the tub is filled with hot water that has been heated elsewhere. Sakurai family (Sakurai-ke 桜井家) residence, Ishikawa Prefecture.

In the Suzuka foothills (Suzuka sanroku 鈴鹿山麓), an area known as Yama-no-ue (山の上, ‘above the mountains'), another type of bath, called tobi-komi furo (飛込み風呂, ‘jump into bath’), has no door, and the tub must be entered from above. As seen in the picture below, the tub (yu-uke ゆうけ) is capped with an inverted basket (fugo 畚) woven from straw; the type is also known as a fugo-buro (ふごぶろ ‘basket bath’). The basket is also called shiuta (しうた), an abbreviation of noshi-futa (載し蓋, ‘place on cap’).

A fugo-buro (ふごぶろ ‘basket bath’) in the Suzuka foothills (Suzuka sanroku 鈴鹿山麓). One enters the bath then lowers the lid from above to ‘steam’. The basket bath is a ‘flat kettle direct fire type’ (hira-gama choku-bi shiki 平釜直火式), but was originally a simple ‘unfired’ type, filled with hot water heated elsewhere. Nose family (Nose-ke 野瀬家) residence, Shiga Prefecture.

The bath below is from the Iga (伊賀) region of the Suzuka foothills. The baths known in Sado as komo-kaburi (こもかぶり, lit. ‘woven straw mat-wear on head’) are of the exact same type; the lid (futa 蓋), as in the Iga type, takes the form of a sedge hat (suge-gasa菅笠). In this example the basket is hung from a string on a pulley suspended from the ceiling, balanced with a counterweight so that it can be operated with a single finger. Both types were once simple tubs into which water heated on a stove was poured; they were later improved into the direct-fire Goemon-buro type.

This bath is of the same type as the one shown above, but with a pulley and counterweight mechanism to make raising and lowering the basket easier. The basket (shiuta (しうた 載蓋) is, like those used on Sado Island, is in the shape of a sedge hat (suge-gasa 菅笠).

In addition to the types described above, there is the formal ‘upper bathroom’ (kami-yokushitsu 上浴室) attached to the upper formal room (kami-zashiki 上座敷) of designated inns (honjin 本陣) and the houses of wealthy farmers (gо̄nо̄ 豪農): hot water bathing (yu-ami 湯浴み) bathrooms that were in most cases called the yu-dono (湯殿 ‘bathing hall’) or yu-ba (湯場 ‘bathing place’). These might be a simple room with floorboards laid to a fall to drain water; or they mightbe located in a part of the doma paved with ceramic or clay tiles, with a bench-form (endai-jо̄ 縁台状) tray laid with a bamboo grate (takesu竹簀), and a tub (yu-uke 湯桶) and water bucket (mizu-oke 水桶) set up at its side. Or, as in the Nijо̄ jinya (二条陣屋), a townhouse (machiya 町家) in Kyо̄to, dating to around the end of the 18th century, there is a tiled and plastered bath (yokusо̄ 浴槽; yokusо̄ can also be translated as ‘bathroom’ or ‘bathing area’) with a ‘cove’ that holds a charcoal fire which heats water to recirculate via convection through holes in the tiles. Heating systems that work on this principle are still used today in modern baths.

The technology for making stave barrels/tubs (oke 桶) advanced in the Muromachi period (Muromachi jidai 室町時代, 1336 - 1573), but the use of these as bathtubs didn’t spread to minka until the custom of bathing became widespread in the mid Edo period (Edo jidai 江戸時代 1603 - 1868). In minka in Kantо̄ (関東), the region of eastern Japan centred on Edo (Tо̄kyо̄), there were elliptical (da-en-gata 楕円形) bath tubs (furo-oke 風呂桶), often with a ‘jujube-shaped’ (natsume-gata なつめ型 or 棗型) iron kettle (tetsu-gama 鉄釜) built into them; varieties include the sue-buro (据え風呂, ‘squat/sit down bath’), oke-buro (桶風呂, ‘barrel bath’) and teppо̄-buro (鉄砲風呂 ‘gun bath’). These baths have no particular need for a bathroom (yoku-shitsu 浴室), so they could be installed in a corner of the earth-floored utility area (doma 土間), or outside, under the eaves.

A primitive tub bath (oke-buro 桶風呂). There is no flue (endо̄ 煙道), only a large feeder opening (taki-guchi 焚口). Its efficiency is poor, requiring four or five hours to heat the water. Toyama Prefecture.

The ‘barrel bath’ or ‘tub bath’ (oke-furo 桶風呂) is portable, so can be set up in a corner of the doma, under the eaves outside as in this example, or elsewhere. Its kettle (kama 釜) has separate feeder opening (taki-guchi 焚口) and exhaust flue (endо̄ 煙道), and represents an improvement in efficiency over what came before.

A scene full of wild charm: an open-air bath (yaten-buro 野天風呂) screened by banana plants (bashou 芭蕉) on Amami (奄美) Island, Kagoshima Prefecture. Also known as kana-buro (鉄風呂, ‘iron bath’), in which the hot water kettle (yu-gama 湯釜) is used as-is as a bathtub (yoku-sо̄ 浴槽), with the fire directly underneath (jikabi-shiki 直火式, ‘direct fire type’). With the addition of a permanent stove (kamado 釜土) structure, this type of bath evolved into the Goemon-buro (五右衛門風呂); it can be seen that this style, together with the portable ‘tub bath’ (oke-buro 桶風呂), in which a heating apparatus (ka-netsu souchi 加熱装置) is attached to a hot water tub (yu-oke 湯桶), represent the two main paths of development of the ‘bathtub’ (yoku-sou 浴槽).

Two simple bath types. On the left, a teppо̄-buro (鉄砲風呂 ‘gun bath’), in which fuel is burnt in an iron tube (tetsu no tsutsu 鉄の筒), which transfers its heat directly into the surrounding water. The bather is protected from burns by a fence (kashо̄ bо̄shi no saku 火傷防止の柵, ‘burn prevention fence’). On the right, a Goemon-buro (五右衛門風呂), with stove (kamado 竃), iron pot (tetsu no nabe 鍋), bath tub (furo-oke 風呂桶), and a board (ita 板) which serves double duty, as a lid (futa-ita 蓋板) when the bath is being heated, then as the ‘bottom board’ (soko-ita 底板), placed in the iron pot so the bather can sit in it without being burned.　

In contrast, in the Kansai (関西) region, broadly western Japan, there were many of what are called Goemon-buro (五右衛門風呂), baths in which water in a bathtub with a cast-iron (chūtetsu 鋳鉄) kettle at its base is heated by a fire directly below. It can burn straw, leaves and trash as fuel. The name derives from Ishikawa Goemon (石川五右衛門), a legendary bandit and Robin Hood-like outlaw folk hero of the Azuchi-Momoyama period (Azuchi-Momoyama jidai 安土桃山時代, 1573 - 1603) who was executed by boiling alive. Like the sue-buro, the Goemon-buro is not portable, and was built in a corner of the interior, outside, or in a dedicated bathroom (yoku-shitsu 浴室) in a detached bathhouse building. As indicated by another of its alternate names Chо̄shū-buro (長州風呂), from long ago the Goemon-buro was distributed in southern Chо̄shū (長州, present-day Yamaguchi Prefecture). According to some sources, the Chо̄shū-buro is distinguished from the Goemon-buro in that the former has a cast-iron cast-iron (chūtetsu 鋳鉄) bathtub (yokusо̄ 浴槽) and a flue (endо̄ 煙道), traditionally constructed of ridge tiles (muna-gawara 棟瓦) or stone

Left, a Goemon-buro (五右衛門風呂) with tub (oke 桶), bottom board (soko-ita 底板), cast-iron (chūtetsu-sei 鋳鉄製) ) bath kettle (furo-gama 風呂釜), and stove (kamado かまど). Right, a Chо̄shū-buro (長州風呂), with cast-iron tub/kettle, bottom board, ‘smoke path’ (endо̄ 煙道), stove, and chimney/flue (entotsu 煙突).

A Chо̄shū-buro built with natural stones with a dedicated bathroom (yoku-shitsu 浴室) built around it.

The sue-buro is thought to have developed from attaching a bathing (yu-ami 湯浴み) barrel (yutо̄ 湯桶) or tub (tarai 盥) to a kettle (kama 釜); while the ‘direct fire type’ (jikabi-shiki 直火式) bath like the Chо̄shū-buro, where a ‘stove’ (kamado 釜土) is built, is thought to have developed out of the kettle (kama 釜) of the kiln bath (kama-buro 窯風呂); in this too, the distinction between hot water (yu 湯) and bath (furo 風呂) seems acknowledged.

A sue-buro in its bathroom setting. The bath is filled from the single cold tap. The fence separating the bather from the hot firebox is visible in the tib, as is the hole above the firebox for the flue, which is not attached. The low door allows the fire to be conveniently fed from outside with firewood stored under the eaves.

Today the majority of minka have their own bathing facilities, but in the past this was not the case. Several households might share a communal bath and heat it on a rota system, with firewood gathered collectively, called gо̄gi (合木, lit. ‘join wood’). There were also arrangements in which each house’s bath was heated in order, and residents would have the use of each others’ facilities, a practice called morai-buro (貰い風呂, ‘receive bath’). In these systems, it was more practical to establish bathhouse structures separate from their houses, as in the picture below.

A detached bath house with a ‘direct fire type’ (jikabi-shiki 直火式) bath, visible on the left, consisting of a wooden tub and shallow iron kettle, with firebox opening below. As a separate structure, the bath house is convenient for morai-buro (貰い風呂), the practice of villagers’ using each others’ baths in turn. Yamagata Prefecture.

As a method of making most efficient use of scarce hot water, a ‘hybrid’ style of bathing, combining hot water bathing and steam bathing, can be found from the east side of Lake Biwa in the Kinki region to the Hokuriku region. In this method of bathing, the bathtub (furo-oke 風呂桶) is deep; when one enters it and closes the lid, it can be sealed off; while washing with the hot water one also bathes in the steam. This method of bathing makes sense in drafty minka in the country’s cold-climate regions. The deep tubs are named after their form: yu-daru (湯樽 ‘bath barrel’), or also simply yu-uke (湯桶 ‘hot water tub’). Though the tubs themselves are deep, the level of water in them is only around 20cm; it is a ‘sealed style’ (mippei-shiki 密閉式) of bathing (nyū-yoku 入浴, lit. ‘enter bathe’) where the hot water is scooped up over one’s body; the method is also called iri-yu (居り湯; here iru 居る means ‘to sit’). On Sado (佐渡) Island, there are baths of the same kind, and the bathtub (furo-oke 風呂桶) is called oroke (おろけ), from iri-yu no oke (居り湯の桶 ‘tub of sitting hot water’).

JAPANESE MINKA XCV - INTERIORS 36: BATHING AREAS 3

The modern Japanese word for ‘bath’ is furo (風呂, lit. ‘wind spine’). The fu of furo refers to air (kūki 空気), and the ro here has the meaning of ‘surround’ or ‘enclose’ (kakou 囲う): furo originally indicated not a ‘bathtub’ or other container to hold hot water, but a relatively airtight room or space, through which air or wind (kaze 風) does not pass. It is in this sense of the word that, in the Hokuriku region, cupboards and toilets (water closets) are also called furo, or at least were until recent times.

In the regions surrounding the Seto Inland Sea (Seto-Naikai 瀬戸内海), there were from long ago furo called iwa-buro or ishi-buro (石風呂, ‘rock/stone bath’). These baths probably originated when sailors (ama 海士), needing to warm themselves, burned driftwood in rock pools. Later, firewood was burnt in enclosures (kake 郭) constructed of stone; once the stones had heated up, the fire was raked out, water was poured onto the perimeter wall, and people took straw mats soaked in seawater into the enclosure, to sit enveloped in ‘steam’ (jо̄ki 蒸気) and hot air (nekki 熱気). These enclosures were usually around eight jо̄ (帖), or 13m², in size, with an entrance around 90cm high and 60cm wide, hung with a mat (mushiro 莚). The exterior side of the stone wall was plastered with earth, and a roof structure was added to keep wind and rain out, and heat and steam in. Bathers did not bathe naked, but in old clothes. This type of bath is distributed across the coastal areas of Yamaguchi, Hiroshima, Okayama, Ehime, and Kagawa Prefectures. Its exact origins are unknown, but it is thought to have come from central Asia via Korea (Chо̄sen 朝鮮). There are places where iwa-buro were still in use until recently, such as one on the outskirts of Imabari City (Imabari-shi今治市), Ehime Prefecture, which may still operate sporadically as a volunteer-staffed tourist attraction.

Primitive bath types.

Left, a ‘salt bath’ (shio-furo 塩風呂). At around 2.7m in height, it is somewhat larger than the Yase kiln bath, but its method of firing and entry are essentially the same. Pine branches are burnt in it, then grass mats soaked in salt water are laid down.

Middle: the Yase ‘kiln bath’ (kama-buro 窯風呂), around 1.8m in height, with a floor area of around three tatami mats, or about 5m2. The floor is laid with flat stones.

Right: a ‘stone bath’ (iwa-buro 石風呂) in Sakurai, Imabari City, Ehime Prefecture, made by hollowing out a natural rock hill. The front slope has been stabilised with concrete.

The Kishimi stone bath (Kishimi ishi-buro 岸見石風呂) in Yamaguchi Prefecture.

Similar in type to the iwa-buro is the ‘kiln bath’ (kama-buro 窯風呂), as in the example in Rakuhoku Yase (洛北八瀬), Kyо̄to City, shown in the image below. This is completely dry hot-air bathing (nekki-yoku 熱気浴) or ‘sweat bathing’ (hakkan-yoku 発汗浴), where the low humidity promotes and optimises the effect of sweating. The relationship of this bath to the iwa-buro is not clear, but in form it is identical to a charcoal kiln (sumiyaki-gama 炭焼窯), and it is reasonably surmised that the idea for the kama-buro came soon after the advent of sumiyaki-gama and pottery/ceramic kilns (tо̄yо̄ 陶窯). Regardless, both iwa-buro and kama-buro are comparatively large-scale in their construction and operation; their interiors are completely dark; their entrances are narrow, and getting in and out of them is awkward: they are primitive in every aspect.

An old kiln bath (kama-buro 窯風呂) preserved in Rakuhoku Yase, Kyо̄to Prefecture.

Steam baths (mushi-buro 蒸し風呂), which accompanied Buddhism to Japan from the continent, are a step more advanced: large iron pots/kettles (tetsu-gama 鉄釜) are used to heat the water, and structures in with various architectural features grew up around them. Famous examples are the ‘warm rooms’ (on-shitsu 温室), essentially sauna, of Hо̄ryūji (法隆寺), Daianji (大安寺) and Saidaiji (西大寺) temples, and the ‘Tang bath’ (kara-furo or kara-buro 唐風呂) of Hokke-ji (法華寺) temple, though in this particular example kara-furo is written 浴室, which is normally read yoku-shitsu (‘bathing room’). Of course these baths were used by the monks and the noble guests they entertained, but they were also open to the general public for bathing while traveling (tabi-yoku 旅浴) or on pilgrimage. These bathing houses are constructed such that within the grand outer building there is a smaller, house-like, gable-roofed structure with a raised ‘grating’ (sunoko 簀の子) floor covered with mats (goza 茣蓙); to its rear is the kama-ba (釜所), the space for the large hot water kettle or cauldron (yu-gama 湯釜), arranged so that steam and heat are drawn under the floor and up into the inner structure.

As mentioned, the earliest public baths (sento 銭湯) were also of the steam-bath type (mushi-buro keishiki 蒸し風呂形式); so humidity and heat did not escape, there was a board wall between the ‘changing room’ (datsui-shitsu 脱衣室) and the bath room (yoku-shitsu 浴室), with a low, gate-like entrance called a zakuro-guchi (ざくろ口 ‘pomegranate door’) through which people had to crawl to enter. This arrangement is effective in preserving temperature, so it survived even after the change to hot water bathing (onyu-yoku 温湯浴). The image below shows a zakuro-guchi style bathroom entry surviving in an inn (hatago-ya 旅籠屋) in Kiso (木曽). In the past, mirrors were polished with pomegranate vinegar, and presumably the name zakuro-guchi arose because the frame of the tiny entrance would be polished to a mirror finish by the bodies of those squeezing through it.

The zakuro-guchi prevents the dispersal of steam; in the past these entrances were even smaller. The yu-dono has a wainscot of stone cladding, and the floor is laid with timber boards that are scored to prevent slipping.

At some point there appeared steam baths for individual, domestic use, called todana-buro (戸棚風呂, ‘cupboard bath’), which were fitted with a wooden door (to 戸) to retain heat and steam.

JAPANESE MINKA XCIV - INTERIORS 35: BATHING AREAS 2

There are two types of non-ritual or ‘hygienic’ bathing (nyūyoku 入浴, lit. ‘enter bathe’) in Japan: hot water bathing (ontо̄-yoku 温湯浴, lit. ‘warm-hot water-bathing’) and steam bathing (jо̄ki-yoku 蒸気浴, lit. ‘steam-air-bathing’). The public bath (sentо̄ 銭湯) is called the furo-ya (風呂屋, lit. ‘bath house’) in Kansai, and yu-ya (湯屋, lit. ‘hot water house’) in Kantо̄, and the room containing the bath (yoku-shitsu 浴室, lit. ‘bathing room’) is called the furo-ba (風呂場, lit. ‘bath place’) or yu-dono (湯殿, lit. ‘hot water hall’), but the conflation or melding of yu (湯, hot water) and furo (風呂, bath) did not begin until the middle of the Edo period (Edo jidai 江戸時代, 1603 - 1868). It was at around that time that public baths appeared in Edo; at first these were for steam bathing (jо̄ki-yoku 蒸気浴), but before long they had switched to hot water bathing. Furo originally referred to steam-bath type (mushi-buro keishiki 蒸し風呂形式) ‘sweat bathing’ (hakkan-yoku 発汗浴), while yu meant ‘immersing oneself in heated water’ (ontо̄-yoku 温湯浴).

The Japanese language has different words for cold water (mizu 水) and hot or heated water (yu 湯). The etymological origin of yu (湯, hot water) is said to be 斎 yu, a reading that survives today only in names; today 斎 is typically read sai, meaning (religious) purification or purity (shо̄jо̄ 浄清). There is the term saikai-mokuyoku (斉戒沐浴), ‘purity admonition ablution bathing’ undertaken before Buddhist or Shintо̄ prayer or other sacred activities, but this is done in a natural (flowing) body of water, i.e. a river or stream, or at a man-made facility such as a well, without regard to the water temperature; mokuyoku/yu-ami (沐浴) means to bathe (mizu-abi 水浴び) in order to purify the body (mi wo kiyomeru 身を清める). Bathing in naturally-occurring hot springs (onsen 温泉) and bathing in hot water were originally undertaken for recuperative or therapeutic (ryо̄yо̄ 療養) aims; long ago, this bathing (nyūyoku) was done wearing a kata-bira (帷子): a thin, unlined robe. As the purpose of bathing gradually shifted towards purifying (jо̄ketsu 浄潔) the body (shintai 身体), bathing came to be undertaken naked.

Gyо̄zui, transferring heated water to a tub (tarai 盥) and washing in it, is the simplest form of hot water bathing, but as indicated by old terms like sensoku/sensuku (洗足 lit. ‘wash feet’), by which gyо̄zui is known in some regions, it was not initially full-body bathing (zenshin-yoku 全身浴).

The yu-dono (湯殿, lit. ‘bathing hall’), the ‘bathroom’ (yoku-shitsu 浴室) built as a separate structure in the shinden-zukuri (寝殿造り) residential complexes of the nobility, was also a facility for heated water mokuyoku. This style of bathroom survived in minka, in the form like that seen in the image below. For the convenience of drainage, the floor boards are given a fall, but otherwise there are no fixtures or fittings.

In a yu-ami style (yu-ami keishiki 湯浴み) ‘bathroom’ (yu-dono 湯殿), there are no facilities or fixtures whatsoever, other than the fall given to the floorboards to ensure good drainage. Of those that survive, many are used as storage rooms.

In the farmhouses of the Iya-dani (祖谷) region of Shikoku, bathroom (yokushitsu 浴室) and toilet (benjo 便所) were built projecting out from the centre of the south-facing facade (omote-gawa 表側), into and beyond the ‘verhandah’ (en 縁). A hole is opened in one part of the bamboo grate (takesu 竹簀) floor to serve as a urinal (shо̄benjo 小便所); the rest of the space is used as a facility for bathing (gyо̄zui 行水) and foot-washing (sensoku 洗足) on returning from the fields (nora-gaeri 野良帰り).

In most minka in the Iya-dani region of Shikoku, the toilet and bathing place project out from the centre of the southern facade. Nishimoto family (Nishimoto-ke 西本家) residence.

In the same way, in one part of the Chūgoku (中国) region, a bathing place (furo-ba 風呂場) and toilet (benjo 便所) are located beside the entrance (toguchi-waki (戸口脇) to the doma, at one end of the facade-side verandah (en 縁); often there is also a large fertiliser pot there. This facility is in front of the zashiki and close to the entrance, and one might think that the smell would be terrible, but a more important consideration was to position it on the southern, sun side, where decomposition was faster and good fertiliser (koyashi 肥し) could be obtained.

The bath is a ‘flue heated type’ (endо̄-kanetsu-shiki 煙道加熱式), called a Chōshū bath (chōshū-buro 長州風呂). The bathwater drains into the ‘toilet pot’ (ben-ko 便壷), also known as the ‘fertiliser pot’ (koe-tsubo 肥壷), to be used along with excreta as fertiliser (hi-ryō 肥料).

JAPANESE MINKA XCIII - INTERIORS 34: BATHING AREAS 1

It is often said that one of the factors behind the ‘traditional’ Japanese love of bathing is that Japan’s warm and humid climate has necessitated it.  However, though public baths (sentо̄ 銭湯) first appeared in the middle of the Edo period (Edo jidai 江戸時代, 1603 - 1868) in urban centres, in regional and rural areas the daily bath is still a relatively recent custom.

In mountain and island villages, where water was not conveniently available, the process of filling a bath — multiple repetitions of walking to a distant communal well, lifting the well bucket, transferring the water into one’s own bucket (mizu-taru 水樽), carrying it home, and emptying it into a bathtub — meant great effort. In lowland rice field areas, where trees are scarce, obtaining firewood was also difficult. Even where there were water and firewood, farmers, harried from dawn to dusk by hard labour, did not have the time nor the mind to heat and enjoy a bath at the end of the day.

A traditional ‘water bucket’ (mizu-oke 水桶) or ‘hand bucket’ (te-oke 手桶).

At best they would stop at the well on returning from the fields (nora-gaeri 野良帰り) to wash their dirty hands and feet and wipe down their bodies; they would only bathe (gyо̄zui 行水, lit. ‘go water’) in the warmer months, or on days when it was warm enough to do so. Even at the beginning of the Taishо̄ era (Taishо̄ jidai, 1912 - 1926), farmers bathed at a frequency of around once or twice a month, as reported in a survey conducted at the time.

Unlike in recent times, with the widespread availability of propane gas and reticulated water, in pre-war rural villages heating large volumes of water was difficult, and immersing oneself up to the neck in a bath generously filled with hot water was still a luxury; the amount of hot water used in bathing was extremely small. In some areas of Kansai, there were baths in which immersion was at most up to the hips, as indicated in the names heso-furo (へそ風呂, lit. ‘belly button bath’) and kin-nurashi (きんぬらし, lit. ‘ball (testicle) wetter’).

An old photograph of a heso-buro in situ.

In farm minka, old bathwater was utilised as fertiliser, and the bathtub often doubled as the fertiliser pot (koe-tsubo 肥壷). From the belief that the richer in dirt (aka 垢) and oil (abura 脂) the bathwater was, the more effective as fertiliser it became, it was normal to use the same bathwater for many days without changing it, until it became thick and muddy and began to smell. Where there was a separate bathtub and fertiliser pot, the bathtub was emptied through a bamboo screen (takesu 竹簀) floor into the koe-tsubo below, and the smell of the disturbed and warmed liquid in the koe-tsubo would fill the bathing place. There is no possibility of a ‘love of bathing’ developing under such conditions.

JAPANESE MINKA XCII - INTERIORS 33: FORMAL AREAS 9

This post will examine ceilings (tenjо̄ 天井) in the formal room (zashiki) and in minka more generally.  The main functions of a ceiling are to hide the complex, ‘messy’ structural timbers of the roof space, to ‘formalise’ and provide ornament to the interior, and to prevent the movement of air, thus preserving heat.  In extremely basic zashiki in farming and mountain village minka, ceilings are not installed, with the beam structure (hari-gumi 梁組) of the roof space (yane-ura 屋根裏) left exposed, but the typical zashiki is provided with a suspended ceiling (tsuri-tenjо̄ 釣り天井).  Rarely, magnificent coffered ceilings (gо̄-tenjо̄ 格天井, ‘lattice ceiling’) can also be found, but zashiki ceilings are normally batten ceilings (sao-buchi tenjо̄ 竿縁天井).

A batten ceiling (sao-buchi tenjо̄ 竿縁天井) in a zashiki. The battens (sao-buchi), as is customary, run parallel to the wall in which the tokonoma is contained, and are spaced at four per ken (間 1.81m), or about 455mm. Isa family (Isa-ke 伊佐家) residence, Kyо̄to Prefecture.

The ceiling battens and ‘cornices’ (mawari-buchi 廻縁) of the batten ceiling (sao-buchi tenjо̄ 竿縁天井) in this ‘high spec’ zashiki, like most of the other timber members visible here, are lacquered (urushi-nuri 漆塗り). Sakurai family (Sakurai-ke 桜井家) residence, Ishikawa Prefecture.

In the sao-buchi tenjо̄, slender battens (sao-buchi 竿縁, lit. ‘pole/rod edge’) are suspended from the roof beams via timber hangers (tsuri-ki 釣木, lit. ‘hang timber’), and thin (perhaps only 3mm or so), wide boards of Japanese cedar (sugi 杉, Cryptomeria japonica) or the like are lapped (ha-gasane 羽重ね lit. ‘wing/feather layering’) over the battens and perpendicular to them.  The boards are usually lapped by 20mm or so; if thicker boards are used, they may be thinned at the lap.

A batten ceiling (sao-buchi tenjо̄ 竿縁天井) illustrated from above and below, showing ceiling boards (tenjо̄-ita 天井板), battens (sao-buchi 竿縁), ‘cornices’ (mawari-buchi 廻り縁), batten hangers (tsuri-ki 吊木 or 釣木), hanger support (tsuri-ki uke 吊木受け), and ‘over battens’ (no-buchi 野縁 or ura-san 裏桟). Common standard pitches for the battens are 303mm, 455mm, 606mm, and 910mm.

Illustration showing various batten (saobuchi さお縁) profiles (keijо̄ 形状) and dimensions (sunpо̄ 寸法). In an example of traditional builders’ understanding of fractal scaling and proportionality in design, dimensions are given not in absolute units but as fractions of the building’s structural post (hashira 柱) dimensions. For example, if the post dimensions were 100mm x 100mm, the batten at top left would be 25mm x 25mm, with 10mm chamfers.

A traditional, labour-intensive method of hanging the battens (sao-buchi さお縁) from the hangers tsuri-ki 釣木), using a type of dovetail joint called yose-ari (寄せあり, lit. ‘draw together ant’) and a peg or wedge (komi-sen 込み栓). The ceiling boards (tenjо̄-ita 天井板) are cut around the joint and the cut is concealed by the batten.

More modern methods of construction: above, the hanger and ‘overbatten’ (no-buchi 野縁) are nailed together; below, the batten (sao-buchi さお縁) is suspended from a wire (tsuri-tessen 釣り鉄線) and screw eye (hiiton ヒートン).

With very thin ceiling boards (tenjо̄-ita 天井板), in this case 3mm, the lap can be formed by simply bending the timber.

Methods used for lapping thicker ceiling boards include: above, thinning a part of one board with a channel so it can be bent over the chamfered edge of the other; and below, inserting the double-bevelled edge of one board into the saw-cut edge of the other.

It is preferred that the sao-buchi run parallel to the wall that the decorative alcove (tokonoma 床の間) is in; the opposite arrangement, when the sao-buchi run perpendicular to the toko wall, is called toko-zashi (床差し, lit. ‘toko facing’) and is strongly disliked.  There are not a few toko-zashi ceilings in old minka, however. 

In the unusual kiri-ko tenjо̄ (切り子天井, lit. ‘cut child ceiling’), ceiling boards and permeable screen panels (sunoko 簀の子), usually of bamboo, are used in combination, the aim being to exhaust the smoke from the firepit (irori 囲炉裏).  These ceilings are found in minka on the warm-climate Hachijо̄ Island (Hachijо̄ jima 八丈島), south of Tо̄kyо̄.  In Japan’s more typical climates, warmer air rising into the roof space not only in itself prevents the room from warming or retaining warmth, but the convection current set up also draws cold air from under the floor and into the room, and so it is said that one should aim for as airtight a ceiling as possible.  In a zashiki with such a ceiling, only charcoal would be used for a fire.

This ceiling, from a minka on Hachijо̄ Island (Hachijо̄ jima 八丈島), is a type of batten ceiling (sao-buchi tenjо̄ 竿縁天井) that combines sections of the typical board (tenjо̄-ita 天井板) and batten construction with sections of screen (sunoko 簀の子) and batten construction, as seen here. This type of ceiling is known as kiri-ko tenjо̄ (切り子天井). Okiyama family (Okiyama-ke 沖山家) residence, Tо̄kyо̄ Prefecture.

Zashiki ceilings, as seen in in the images included here, are almost always sao-buchi tenjо̄, but if an enclosed ‘verandah’ (engawa 縁側) is associated with the zashiki, its roof structure is often left exposed. As the engawa is at the building perimeter in the ‘eave space’ (geya 下屋) beyond the exterior wall plane, the roof structure here typically only consists of rafters (taruki 垂木) and so is neater in appearance than the more complex roof structure over the main jо̄ya (上屋) space of the building where the zashiki is located. Later-period tile-clad (kawara-buki 瓦葺き) or board-clad (ita-buki 板葺き) roofs’ under-eave structures consisted of rafters, sub-roof boards (noji-ita 野地板), tile battens (kawara-zan 瓦桟 or komai 小舞) and anti-ponding boards (hiro-komai 広小舞); when left visible, these members were all finished with a plane (kanna 鉋), and good quality timber, free of knots, cracks or other defects, was used for noji-ita, improving their presentability. These ‘beautified’ noji-ita are called keshо̄ noji-ita (化粧野地板), and such roofs are called keshо̄ yane-ura (化粧屋根裏, lit. ‘cosmetic roof underside’). In thatched roofs (kusa-yane 草屋根, lit. ‘grass roof’) too, when the underside of the roof is left visible, reed screens (yoshizu 葭簀) or the like function as the keshо̄-noji (化粧野地, ‘cosmetic subroof’): they are laid on the rafters, with the thatch laid over them.

The enclosed geya space ‘verandah’ (engawa 縁側) of this building boasts a fine keshо̄ yane-ura (化粧屋根裏, lit. ‘cosmetic roof underside’) with very high quality defect-free rafters (taruki 垂木) and cosmetic sub-roof boards (keshо̄ noji-ita 化粧野地板).

In rooms in which the tea ceremony (茶席 chaseki) is conducted, there may be a desire to emphasise the design of the geya roof structure as a point of appreciation and conversation, so the keshо̄ yane-ura of the geya is incorporated into the room as an interior compositional element, resulting in what is called a kake-komi tenjо̄ (掛込み天井, lit. ‘bring in ceiling’): a ceiling that combines a flat section (hira tenjо̄ 平天井) and a sloped or ‘lean-to’ section (kata-nagare tenjо̄ 片流れ天井); the sloped section of ceiling may be over the genuine perimeter geya space of the structure, or it may be ‘faked’, within the interior jо̄ya space, or even in a modern apartment.

The rear of this tea-room (cha-shitsu 茶室) features a kake-komi tenjо̄ (掛込み天井) that incorporates (or imitates) the geya space roof.

As for ceilings over areas other than the zashiki, often the earth-floored utility area (doma 土間) of minka had a ‘cosmetic roof space’ (keshо̄ koyaura 化粧小屋裏), such as bamboo screens (takesu 竹簀) laid over the beams, to form what is known as a takesu tenjо̄ (竹簀天井, ‘bamboo screen ceiling’). This allowed smoke from the stove (kamado 釜土) or irori (囲炉裏) to rise freely up into the roof space (koya-ura 小屋裏). In Kansai (western Honshū) minka, the kamado was built in a separate part of the doma called the kama-ya (釜屋), and only the ceiling above this part was made permeable; the ceiling over the rest of the doma was airtight. With a ceiling of takesu alone, air flow is excessive, so the upper side of the takesu can be plastered over with clay or earth (tsuchi 土); such a ceiling is called yamato tenjо̄ (大和天井). Yamato tenjо̄ are not used in zashiki, but may be found above the semi-formal dei (でい) and the dining room/kitchen (daidokoro だいどころ or daidoko だいどこ). Alternatively, if the space above the dei or daidoko is used as a kind of attic floor known as tsushi ni-kai (厨子二階), the underside of that floor serves as the ceiling for those spaces below. This type of ceiling is called a neda tenjо̄ (根太天井 ‘joist ceiling’), hari tenjо̄ (梁天井 ‘beam ceiling’), or chikara tenjо̄ (力天井, ‘strength ceiling’). Such ceilings are considered utilitarian (shita-mawari 下回り), in contrast to the formal sao-buchi tenjо̄ of the zashiki.

The main ceiling in this image is a bamboo screen ceiling (sunoko tenjо̄ 簀の子天井), spread on its upper side with a floor of matting (mushiro 莚). The sloped ‘descending ceiling’ (kudari tenjо̄ 下り天井) over the eave space (geya 下屋) is a ‘cosmetic under-roof’ (keshо̄ koya-ura 化粧小屋裏) consisting of reed screens (yoshizu 葭簀) laid over bamboo rafters (taruki 垂木 or 棰). Nomura family (Nomura-ke 野村家) residence, Shiga Prefecture.

In this type of bamboo screen ceiling (sunoko tenjо̄ 簀の子天井) known as yamato tenjо̄ (大和天井), the upper side of the screen is plastered with clay. Yamato tenjо̄ are often used above the earth-floored utility area (doma 土間) and above the non-formal gathering or ‘living’ rooms of the dwelling. Hirai family (Hirai-ke 平井家), Shiga Prefecture.

JAPANESE MINKA XCI - INTERIORS 32: FORMAL AREAS 8

In the course of this series of minka, many mentions have already been made of the en-gawa (縁側, lit. ‘edge side’), sometimes just en (縁, ‘edge’): the ‘verandah’ space of the minka.  Here, we will examine the engawa in the context of its place and role in the formal room, the zashiki (座敷).

The en in this minka connects the semi-formal dei (でい) and formal zashiki (ざしき). The verandah boards are laid perpendicular to the walls of the building. The outer edge of the en is fitted with sliding storm shutters of the saikо̄ amado (採光雨戸, ‘lighting storm shutter’) type, allowing some light to enter the interior even when the shutters are drawn.

In minka, the engawa attached to the zashiki serves as its formal entrance. Where there is a ‘wraparound verandah’ or ‘return verandah’ (mawari-en 回り縁, lit. ‘rotation edge’) running around two sides of the zashiki, one leg of the en will face the viewing garden (kanshо̄ teien 観照庭園), organically connecting zashiki and garden and forming a climatic buffer zone, as well as functioning as a corridor necessary in entertaining/receiving/serving (settai 接待) guests in the zashiki.

A wraparound or return verandah (mawari-en 回り縁) serves the front zashiki (mae-no-zashiki まえのざしき) and rear zashiki (oku-zashiki おくざしき) of this minka. The verandah boards are laid parallel to the walls of the building. Sliding storm shutters (amado 雨戸), indicated by dashed lines, are fitted to the outer edge of the en and stored in pockets at the corner and upper end of the mawari-en.

The engawa of the zashiki is thought to have its origins in the kiri-me en (切目縁, lit. ‘cut eye edge’), a kind of verandah consisting of thick, wide boards laid perpendicular to the external wall perimeter (shūen 周縁) of temples and shrines (dо̄miya 堂宮).

An eye-level view of a kiri-me en (切目縁) on a temple building, showing the exposed end-grain (kiri-me 切目) of the boards.

The boards at the corners of a kiri-me en can be resolved with a square ‘tо̄fu board’ (tо̄fu-ita 豆腐板), as seen here.

Here the kiri-me en corners are resolved by laying the boards radially.

There is also the iri-engawa (入縁側), an en formed under the eaves (geya下屋) that consists of long, narrow boards (en-kure 縁槫れ or kure-en 槫縁) laid parallel to the wall of the building.

Illustration showing the difference between kure-en (槫縁) and kiri-me en (切目縁).

In either case, if there are storm shutters (amado 雨戸, lit. ‘rain door’), and they are located at the immediate outside of the shо̄ji in the exterior wall plane, the en is a gai-en (外縁, lit. ‘outside en’) or a nure-en (濡れ縁, lit. ‘wetted en’), an old style of en exposed to the weather.

A nure-en (濡れ縁), protected by very deep eaves.

Later the amado came to be installed at the external edge of the en, thus bringing the en space into the interior to a degree to form a nai-en (内縁, lit. ‘inside en’); nure-en or gai-en then refers to a ‘secondary’ en exterior to the amado. With the introduction of glass, glazed shо̄ji joined the amado in this position, completing the transformation of the en into an interior corridor (rо̄ka 廊下, lit. ‘corridor under’).

In this old, pre-glass minka, the shouji and amado are both in the external wall plane; the narrow, bench-like en is exposed (nure-en) and laid with two wide, thick boards that run parallel to the wall. There is a pair of storm shutters (amado 雨戸), running in two parallel tracks, in each bay within the depth of the posts, so only half the openings can be utilised to admit light into the interior, unless the amado are removed completely and stored elsewhere.

Another view of the minka shown above.

This image shows two different design solutions. At left, the storm shutters (amado) are in the external wall plane with the shо̄ji; the en is a simple, seemingly unfixed, bench; at centre/right of the image, the amado are positioned at the external edge of the en, with the shо̄ji in the external wall plane, forming a semi-internal corridor.

A tatami-laid iri-gawa en, with papered shо̄ji on its interior side, and amado on its exterior side, all running in a single groove and retracted into a shutter box (to-bukuro 戸袋, lit. ‘door bag’). Exterior to the amado is a narrow nure-en at a lower level, called an ochi-en (落縁, ‘dropped en’), with kure-en (槫縁) boards.

A nai-en at a lower level to the main floor, with papered shо̄ji, storm shutters (amado) running in a single groove and retracted into a shutter box (to-bukuro 戸袋), and kure-en (槫縁) boards.

A wide en is called an en-no-ma (縁の間, ‘en space’), hiro-en (広縁, ‘wide en’) or iri-gawa (入側, ‘enter side’), and may be fully laid with tatami mats, or half with tatami and half with floor boards.

This iri-gawa hiro-en (入側広縁) consists of a tatami-laid (tatami-shiki 畳敷き) part and a part laid with long, narrow en-kure boards en-kure-ita 縁槫板). A very narrow bamboo grate (take-su 竹簀) ‘dropped en’ (ochi-en 落縁) is visible between the hiro-en and the garden.

Here the sliding storm shutters (amado) to the exterior side of the hiro-en do not all run in a single track to retract into a shutter box (tobukuro 戸袋) at the end of the run; rather there is a pair of amado, running in two parallel tracks, in each bay between the posts, which are at one ken (1.81m) centres. Thus only half the exterior side of the hiro-en can be opened up, unless the amado are removed completely and stored elsewhere.

Here the end-grain of the kiri-me boards is protected by a board or bearer running parallel to the wall. Kyо̄to Prefecture.

The board-floored hiro-en (広縁, lit. ‘wide en’) in front of zashiki in mountain and farming village minka, where there are no visits from distinguished guests, is often used for drying grain, or as a place for weaving or other hand-work. Once the en is ‘interiorised’, a narrow external nure-en becomes even more necessary, for entry and exit, and for relating the house to the garden. Such nure-en are called ochi-en (落ち縁 ‘dropped en’), gai-en (外縁 ‘outside en’), hoka-en (ほかえん ‘other en’), hi-en (ひえん ‘day/sun en’), fumi-kudari (踏み下り ‘step descend’), etc.

An en or part of an en that serves a guest toilet (kami-benjo or uwa-benjo 上便所) is called the chiku-en (竹縁 ‘bamboo en’), or naguri-en (名栗縁), after the materials of its construction; naguri (名栗) refers to a timber finishing technique where patterns are worked into boards or square members with a chisel or adze.

JAPANESE MINKA XC - INTERIORS 31: FORMAL AREAS 7

The akari-shо̄ji, the paper-covered timber lattice sliding partition introduced in last week’s post, is arguably more representative and expressive of the aesthetic of Japanese architecture than any other architectural element.

Akari-shо̄ji used in the main opening and above the transom, demonstrating the dappling and shadow effects characteristic of shо̄ji, not possible with glazed windows.

Today generally just called shо̄ji, the akari-shо̄ji did not appear primarily for aesthetic reasons, however. In practical terms, it functions to obstruct wind and drafts but permit the passage of light, and the precision of its joinery means that it can be opened and closed with a light touch while also being reasonably robust. Its great weakness, however, is its vulnerability to rain and water.

It is thought that the earliest shо̄ji developed out of the shitomi (蔀) or shitomi-do (蔀戸), external wall fittings that date back to the Heian period or earlier and were the principal opening devices of the Buddhist temples and shinden (神殿) residences of that time. Shitomi are characteristically top-hung, and generally present as a fine square lattice that is either ‘blind’ (backed with thin timber boards) or hung with paper.

Illustration showing ha-jitomi (半蔀).

Paper-covered ha-jitomi (半蔀) on a Buddhist temple. The upper panels are top-hung and suspended from iron hooks that hang down from the eave rafters.

Primitive strut-propped board shitomi in a warm-climate minka.

In particular, the ha-jitomi (半蔀, ‘half shitomi’), consisting of a top-hung and outwards-opening upper lattice shutter and a lower removeable lattice panel, evolved into the koshi-daka shо̄ji (腰高障子 lit. ‘waist high shо̄ji’), with an upper half of papered akari-shо̄ji and a lower half of solid board (itado 板戸), which was widespread before the development of sliding storm shutters (amado 雨戸 ‘rain door’) from the later Edo period. The papered upper half of the koshi-daka shо̄ji is protected from the weather by the deep eaves typically found on traditional Japanese buildings.

A pair of painted koshi-daka shо̄ji (腰高障子) from the Azuchi-Momoyama period (Azuchi-Momoyama jidai 安土桃山時代 , 1573 - 1603).

After the introduction of amado, ‘low-waisted’ shо̄ji resembling the modern type and ‘waistless’ shо̄ji called mizu-shо̄ji (水障子, ‘water shо̄ji), mizu-goshi shо̄ji (水腰障子, ‘water waist shо̄ji’) or koshi-nashi shо̄ji (腰無障子, ‘waistless shо̄ji’) appeared, in a rich variety of designs.

Sliding storm shutters (amado 雨戸) protect the akari-shо̄ji in this minka.

It the era before glass, the paper of shо̄ji in external walls could be further protected against rain with a finish of tung oil (kiri-abura 桐油); these oil paper (abura-gami 油紙) shо̄ji were called ‘oil shо̄ji’ (abura shо̄ji 油障子). In snowy regions, in preparation against high snowfall, there are shо̄ji with extremely high waists, and fittings that are perhaps better categorised as ‘lantern storm shutters’ than shо̄ji, called ame-shо̄ji (雨障子, ‘rain shо̄ji) or yamato-shо̄ji (大和障子).

Illustration of a generic ‘waisted’ (koshi-zuke 腰付け) akari-shо̄ji with the parts labelled: top rail (kami-zan 上桟), lattice ‘muntins’ (kumiko 組子), stiles (kamachi 框), mid-rail (naka-zan 中桟), ‘waist board’ (koshi-ita 腰板), and bottom rail (shimo-zan 下桟).

Illustration of some of the common variants of the basic shо̄ji. Top row: koshi-zuke tate-shige yoko-bitai iri (腰付縦しげ横額入り, lit. ‘waisted vertical frequent horizontal picture-frame inserted’); koshi-zuke ara-gumi о̄-bitai iri (腰付荒組大額入り, lit. ‘waisted rough grid big picture-frame inserted’); mizu-koshi ara-gumi yuki-mi (水腰粗組雪見, lit. ‘water waisted rough grid snow view’). Bottom row: koshi-zuke yoko-shige bitai iri (腰付横しげ額入り, lit. ‘waisted horizontal frequent picture-frame inserted’); mizu-koshi ara-gumi mu-chi (水腰粗組無地, lit. ‘water waisted rough grid no ground’); koshi-zuke yoko-shige neko-ma (腰付横しげ猫間, lit. ‘waisted horizontal frequent cat space’).

Mizu-shо̄ji (水障子) with no ‘waist board’ (koshi-ita 腰板), only a bottom rail (shimo-zan 下桟), so the paper and lattice (kumiko 組子) extend almost to the floor.

The introduction of glass saw the development of shо̄ji with a papered upper half and glazed lower half, called yuki-mi shо̄ji (雪見障子, ‘snow viewing shо̄ji’), and neko-ma shо̄ji (猫間障子, ‘cat space shо̄ji’), with operable papered panels that can be slid aside to reveal or hide the glazing and the view as desired.  Cats are notorious for destroying shо̄ji paper, and the neko-ma name and design might come from a motivation to reduce this likelihood by providing them with a view out.  

Yuki-mi shо̄ji (雪見障子) in the end wall of a relatively modern dwelling

The top of the shо̄ji and other types of sliding partition run in grooves cut into the opening head (kamoi 鴨居); in zashiki, there is typically a picture rail or ‘frieze rail’ (nageshi 長押) above the kamoi, but in minka the nageshi might be omitted, and instead a deep lintel beam (sashi-gamoi 差鴨居), with grooved soffit, serves both functionally, to hold the sliding partitions, and visually, as a kind of picture rail.

Even in minka of the higher classes there are examples, as here, where a ‘frieze rail’ (nageshi 長押) is not present, and a deep, grooved lintel beam (sashi-gamoi 差鴨居) is used instead. The transom panels (ranma 欄間) between the rooms are magnificent ‘through-carved’ (tо̄shi-bori 透し彫り) ‘board ranma’ (ita-ranma 板欄間), while between the far room and the external verandah (en 縁) there are sliding shо̄ji panels. The opaque fusuma (襖) partitions are painted in the ‘flower-and-bird picture’ (kachо̄-zu 花鳥図) genre by a famous artist. О̄kaku family (О̄sumi-ke 大角家) residence, Shiga Prefecture, an Important Cultural Property.　東海道 の本陣　梅の木　茶屋是斉屋

Conventionally there are transom panels (ranma 欄間) between the nageshi and the ceiling; in the partition walls between rooms, this is normally a carved ita-ranma. In regional areas you can find many interesting ranma carved with rustic, bold designs; but in the strictly formal ‘palace style’ (goten-fū 御殿風), ranma panels of very finely spaced vertical timber members called osa-ranma (筬欄間, lit. ‘reed ranma’), hanazama (花狹間, lit. ‘flower narrow space’), and take-no-fushi ranma (竹の節欄間 lit. ‘bamboo node ranma’) are used.

Two styles of ranma are used in this space: on the left, an elaborately-carved ita-ranma (板欄間); on the right, a fine lattice osa-ranma (筬欄間).

In the transom between the zashiki and the ‘verandah’ engawa, there is normally a papered lattice sliding shо̄ji panels, but in more ‘stylish’ or fashionable 洒落た zashiki, ‘comb-shaped’ ranma (kushi-kata ranma 櫛形欄間) and ‘corner cut’ ranma (sumi-kiri ranma 隅切欄間) shitaji-mado (下地窓, a window formed by omitting the plaster from part of the wall, leaving the lath exposed, and without a surrounding timber frame) can be found, perhaps covered with a ‘hanging shо̄ji’ (kake-shо̄ji 掛障子).

Generally the zashiki is accompanied on at least one of its sides by an engawa (縁側, often simply en 縁), the perimeter ‘verandah’ space that mediates between interior and exterior in minka. The openings in the wall or walls between the zashiki and the engawa are usually equipped with shо̄ji (障子): sliding partitions consisting of a timber lattice frame with thin translucent paper glued to one side.

Shо̄ji in the external wall of a sukiya-zukuri style building. When shо̄ji are in the external wall, the paper is on the external side.

The word shо̄ji means ‘obstructing thing’ (sawaru mono 障るもの); originally, fusuma (襖, thin, opaque sliding panels clad on both sides with thick paper), timber board partitions (itado 板戸) and other similar room-partitioning fittings (tategu 建具) were all called shо̄ji, and the translucent lattice-and-paper panels that we know as shо̄ji today were called akari-shо̄ji (明り障子, ‘lantern shо̄ji), which is still their formal or ‘correct’ name.

Where an upper and lower zashiki (kami-zashiki 上座敷 and shimo-zashiki 下座敷) are present, the boundary between them is partitioned with fusuma.

A modern house or apartment fitted with shо̄ji on the external window and fusuma between rooms.

The origins of shо̄ji (in the broader sense) are thought to lie in the standing screens (tsui-tate 衝立) and standing folding screens (byо̄bu 屏風) that date back to at least the shinden-zukuri (寝殿造り), the residences of Heian period (Heian jidai 平安時代, 794 - 1185) nobility.

A standing folding screen (byо̄bu 屏風).

Early shо̄ji were silk-covered (nuno-shо̄ji 布障子 ‘fabric shо̄ji’). At the end of the Heian period, kara-kami shо̄ji (唐紙障子) appeared, covered with ‘Tang paper’ (kara-kami 唐紙) imported from China. In the Kamakura period (Kamakura jidai 鎌倉時代, 1185 - 1333) these spread from the houses of the nobility to upper class residences in general, and in some regions fusuma are still called karakami. Akari-shо̄ji also appeared around this time, but only became more widespread from the Muromachi period (Muromachi jidai 室町時代, 1336 - 1573) on, and then still only in palaces (kyūden 宮殿), Buddhist temples (ji-in 寺院), and the residences of the extreme upper strata of society. For commoners, paper was still a distant luxury.

Fusuma and akari-shо̄ji did not appear in minka until around the middle of the Edo period (Edo jidai 江戸時代 1603 - 1868), but again this was only in relatively affluent minka in the more advanced and sophisticated regions of the country. In mountain villages and low socio-economic status minka, exterior openings consisted of paper directly applied to kiri-mado (切り窓, ‘cut window’, slot-like openings cut into wall boards), shita-ji mado (下地窓, areas of wattle-and-daub wall where the daub is omitted, exposing the wattle) or fixed timber lattice (kо̄shi 格子); even where they existed, akari-shо̄ji were limited to only the main or formal rooms of the dwelling, such as the zashiki.

Like the tokonoma, the toko-waki (床脇, lit. ‘toko flank’) is an alcove, but where the tokonoma is purely ornamental, the toko-waki combines an ornamental role with functionality. As the name suggests, the toko-waki is located next to the tokonoma and in the same wall; it is on the other side of the tokonoma to the shoin. The toko-waki typically contains some combination of upper suspended cupboards or cabinets (tenbukuro todana 天袋戸棚, lit. ‘heaven bag door shelf’), an open shelf (tana 棚) or shelves, and lower cabinets (chibukurotodana 地袋戸棚, lit. ‘earth bag door shelf’).

In this modern zashiki, the tokonoma (床の間) is between the toko-waki (床脇) and the shoin (書院), which is conventional, but there is also a closet (oshi-ire 押入) in the same wall, which detracts from the shoin-toknoma-tokowaki composition.

The toko-waki also shares with the tokonoma a likely origin in the residences of Buddhist priests (sо̄bо̄ 僧房, lit. ‘priest chamber’), specifically in the shelves used to store sutras (kyо̄kan 経巻). It has also been suggested that the toko-waki began as a two-tier shelf used to hold everyday items, or as a piece of moveable furniture something like the ‘fan shelf’ (sensu-dana 扇子棚) that eventually evolved into a built-in permanent fixture. The toko-waki is decorated with various craft items, and is also a place to store the valuable works of art, vases, etc. that are displayed in the tokonoma.

A ‘fan shelf’ (sensu-dana 扇子棚).

Elements of the toko-waki labelled: the upper cabinet or cupboard (ten-bukuro 天袋) and ‘head’ (kamoi 鴨居), staggered shelves (chigai-dana 違棚) with ‘shrimp post’ (ebi-tsuka 海老束) and ‘brush return’ (fude-kaeshi), lower cabinet (ji-bukuro 地袋) with sill (oki-jikii 置敷居) and half-post or end-post (hо̄date 方立 or han-tsuka 半束), and ‘ground board’ (ji-ita 地板),

The design of the toko-waki is extremely free, and there are over a hundred different ‘templates’ (hinagata 雛形). A single shelf (tana 棚) running the full width of the tokowaki is called a tо̄shi-dana (通し棚, lit. ‘passing shelf’) or hitomoji-dana (一文字棚, lit. ‘one character shelf’, from its resemblance to the character hito 一). The shelf style most commonly associated with the toko-waki is known as chigai-dana (違い棚, ‘staggered shelf’): two shelves arranged one above the other and offset in a ‘mist pattern’ (kasumi-gata 霞型).

Mist pattern (kasumigata 霞型).

In this style, a turned-up strip of moulding called a (fude-kaeshi 筆返し, lit. ‘brush return’) is attached to the end of the upper shelf, which is supported off the lower shelf by a vertical piece called the ebi-tsuka (海老束, lit. ‘shrimp post’). Other styles include han-dana (半棚, ‘half shelf’), tsuka-tana (束棚, ‘post shelf’), tsuri-dana (釣り棚, ‘fishing shelf’), and sumi-tana (隅棚, ‘corner shelf’). Similarly, the cabinets may run the full width of the toko-waki, or be half-width. The rear wall of the toko-waki might contain a window in any number of styles.

Elements of the chigai-dana (違棚): ‘brush return’ (fude-kaeshi 筆返し) with ‘stop’ (tomari とまり) and ‘pigeon breast’ (hato-mune 鳩胸), ‘shrimp post’ (ebi-tsuka 海老束).

In minka, the toko-waki might be absent, with the tatami floor extended to the wall; alternatively, there may be a Buddhist altar (butsudan 仏壇), or, in more recent minka, a closet (oshi-ire 押入) occuppying the alcove in place of the toko-waki. Sometimes the walls surrounding the tokotoma and toko-waki are not earth walls (dokabe 土壁) or plaster-finished, but are lined with paper of the same kind as is used on the thin opaque sliding partitions called fusuma (襖). This style is called hari-tsuke (貼付け, lit. ‘pasting’ ‘sticking’ or ‘attaching’), and is mainly found in higher-class residences.

JAPANESE MINKA LXXXVII - INTERIORS 28: FORMAL AREAS 4

After examining the tokonoma in the last few posts, this week and next we will look at the two elements that flank the tokonoma in the ‘standard’ zashiki: the shoin and the toko-waki. This week’s post will consider the former.

The shoin first appeared in the residences or residential quarters of Buddhist priests (sо̄bо̄ 僧房) as an ‘office’ or ‘study’ for copying sutras and reading. It was never a room in itself, however, but a windowed alcove projecting out into the ‘verandah’ (engawa 縁側), with an inbuilt desk. This was called a dashifu dzukue (出府机 or 出文机, lit. ‘project office desk’ or ‘project writing desk’), idashifumi dana (出文棚, lit. ‘project writing shelf’), etc., and is thought to have first appeared in the Kamakura Period (Kamakura jidai 鎌倉時代, 1185 - 1333). It became fashionable to decorate the shoin with inkstones (suzuri 硯), brushes and ink (筆墨 hitsuboku) ‘letter boxes’ (fubako 文箱) and other stationary items; eventually the shoin itself was integrated into the design of the tokonoma and developed into an important decorative element in the zashiki in its own right.

The shoin is almost always built into the wall flanking the tokonoma, and so is perpendicular to the tokonoma. A width (or length) of one ken (1.81 metres) is typical, and served the original purpose of the shoin as a desk. Older style shoin usually start at the tokonoma sill, with the flanking wall of the tokonoma left blind, which may mean that the tokonoma doesn’t receive enough light. This problem can be addressed by bringing the shoin into the tokonoma, so that the shoin window becomes part of the tokonoma flanking wall. The half-ken part of the shoin in the tokonoma is called the kakekomi (駈けこみ ‘advancing in’).

Where there is a mawari-en (回り縁) or ‘wraparound verandah’, there are rare occasions where the shoin is built alongside the tokonoma, so shoin and tokonoma face the same direction.

The ‘classic’ shoin projects out into the engawa and is called de-shoin (出書院, ‘projecting shoin’) or tsuke-shoin (付書院 ‘attached shoin’). The simplified or abbreviated non-projecting style of shoin is known as hira-shoin (平書院 ‘flat shoin’). The hira-shoin may even dispense with the ‘desk’ (kо̄-ita 甲板) element altogether, leaving only the window.

The shoin window normally presents with a lattice-and-paper transom or a carved ita-ranma (板欄間) transom fitted in its upper section. In the ‘standard’ shoin, the lower, main opening is four shо̄ji, but variants such as the round window (maru-mado 丸窓), ‘horn frame window’ (tsunogara-mado 角柄窓), ‘flame window’ (katо̄-mado 火灯窓 or 花頭窓), and ‘wattle window’ (shitaji-mado 下地窓) are also employed. Alternate names for the shoin include akari-shoin (明り書院, ‘lantern shoin’), shoin-doko (書院床), etc. In Yamagata Prefecture there are areas where akari-doko is abbreviated to aka-doko.

The tokonoma (left) and shoin (書院, right) of an older-style zashiki, in which tokonoma, as here, are generally shallow. The projection of the de-shoin (出書院) is roughly the same depth as that of the tokonoma. The shо̄ji of this shoin have ‘wainscot panels’ (koshi-ita 腰板) and are in the fuki-yose (吹寄せ) style, meaning they feature grouped (in this case doubled and tripled) ‘muntins’ (san 桟).

Here the shoin (left) occupies the place normally held by the toko-waki; conversely, one could say that the toko-waki has a shoin-like design.

To continue on from last week’s post on the ornamental alcove (tokonoma 床の間 or toko 床) of the formal room (zashiki 座敷) of the minka, today we will consider some aspects of tokonoma design.

In the standard zashiki layout, the ‘verandah’ (engawa 縁側) and ‘study’ (shoin 書院) are to the right of the tokonoma, and to its left is the toko-waki (床脇, lit. ‘toko flank’) alcove, which often contains a shelf or shelves, particularly the characteristic ‘staggered shelves’ called chigai-dana (違い棚), and upper cabinets (tenbukuro 天袋). This ‘correct’ tokonoma layout is called hon-doko (本床, ‘true toko’); the opposite arrangement, with engawa and shoin on the left and toko-waki on the right, is called gyaku-toko (逆床, ‘reverse toko’), but is probably just as common.

The interior ‘facade’ elevation of a zashiki, in gyaku-toko configuration, with the toknoma (床の間) on the left, the shoin (書院) to the left of the tokonoma, and the toko-waki (床脇) to the right..

The element of the tokonoma that most draws the eye is the toko post (toko-bashira 床柱), which conventionally stands in the centre of the ‘front’ elevation of the room.

Another gyaku-toko configuration. The toko post (toko-bashira 床柱) which occupies a prominent position at or near the centre of the field of view. Other main elements of the tokonoma are labelled: The toko sill (toko-gamachi 床框); the ‘sill stump’ (kamachi-zuka 框束); the toko board (toko-ita 床板); the ‘skirting board’ (zoukin-zuri 雑巾摺); the floor board in front of the toko (ji-ita); and the toko head timber (otoshi-kake 落掛).

In strictly formal zashiki, the toko-bashira is a large-section square post, but in minka it might be a sugi (杉, Cryptomeria japonica) post, perhaps in a style called men-kawa-bashira (面皮柱, ‘face skin post’), where a log is partially squared off into four faces, leaving the natural rounded corners; a ‘scaffold pole’ (shiba maruta しば丸太, lit. ‘firewood log’); or some other informal, eccentric (henboku 変木, lit. ‘strange timber’) or ‘name’ (meiboku 名木, lit. ‘name timber’) variety of post.

Squared log posts (centre) known as men-kawa bashira (面皮柱).

In the wall behind the toko-bashira, between the tokonoma and the tokowaki, there will often be a low opening called the chin-kuguri (狆潜り, lit. ‘Pekingese underpass’) whose purpose is to throw more light into the tokowaki.

In a conventional tokonoma design, the chin-kuguri (ちんくぐり) opening between the tokonoma and toko-waki is around 40 - 60cm high.

A somewhat garish chin-gukuri made with a section of hollow log.

The front bulkhead wall (tare-kabe 垂れ壁, lit. ‘hang down wall’) above the tokonoma opening is terminated with a kamoi (鴨居) or ‘head timber’ called the otoshi-gake (落とし掛); the otoshi-gake is set at a higher position than the kamoi in the rest of the room, which imparts to it a dignified aspect, and also gives a clearer view of a hanging scroll in the alcove. The otoshi-gake may be only slightly higher than the nageshi, or it may be significantly higher, as in the example below.

In this example, the tokonoma head timber, known as the otoshi-gake (落とし掛) is set significantly higher than the regular head ‘lintel’ (kamoi 鴨居) and picture rail (nageshi) that run around the rest of the zashiki at ‘head datum’ (uchi-nori 内法) height. The effect of the chin-kuguri in bringing more light into the toko-waki is evident here.

When the zashiki is run around with a ‘picture rail’ (nageshi 長押), the point where the nageshi meets and terminates at the tokobashira the can be resolved via various devices, such as the old-fashioned makura-sabaki (枕捌き, lit. ‘pillow handling’) or the hina-dome (雛止め, lit. ‘chick stop’); today the junction is typically handled with what is known as kiri-me dou-tsuki (切目胴突 or 切目胴付き), where the nageshi is extended across 7/10ths the width of the face of the tokobashira.

In the makura-sabaki style, the nageshi wraps around the toko-bashira to terminate on its rear face.

The floor sill (kamachi 框) of the toko, called the toko-kamachi or toko-gamachi (床框), is often around 12 - 18cm high, thus the floor of the toko is also this much higher than the tatami floor of the zashiki itself. In the country and in older minka it is generally even higher, with a toko floor consisting of a thick board, known as ita-doko (板床, lit. ‘board floor’) and a kekomi-ita (蹴込み板, lit. ‘kick-in board’) between it and the tatami.

Toko sills (kamachi 框) are conventionally finished in black lacquer (kuro-urushi-nuri　黒漆塗り), called also roiro-gamachi (ろいろ框), but hardwood sills with a ‘rubbed lacquer’ (suri-nushi 摺り漆) finish are also found; a more informal style might employ a log with the thick stumps of the lopped branches (太枝落し futoeda otoshi) still on it.

As mentioned, the classic floor of the standard toko is normally laid with tatami; this style is known as hon-doko (本床), not to be confused with the hon-doko discussed above, which refers to the ‘handedness’ of the zashiki. Usuberi tatami (薄縁畳, lit. ‘thin edge tatami’), tatami with a thin edging of patterned fabric), and ita-datami (板畳, lit. ‘board tatami’, not actually tatami at all, but a section of boarded floor in an otherwise tatami-laid room) are also found. In the countryside, thick planks of Japanese zelkova (keyaki 欅, Zelkova serrata), Japanese horse chestnut (tochinoki, Aesculus turbinata) or sawtooth oak (kunugi, Quercus acutissima), both written 橡, or pine (matsu 松) with an interesting grain or figure (moku 杢) were favoured.

An ita-datami (‘board tatami’) floored tokonoma. The sill edge of the board terminates at the wall against a ‘sill stump’ (kamachi-dzuka 框束).

The ceiling over the tokonoma is higher than that of the main ceiling of the room, so as to be able to accommodate long scrolls, and so it is not visible when sitting before the toko with its high otoshi-kake. It often consists of a single board of figured timber (mokuita 杢板), known as a kagami-tenjou (鏡天井, ‘mirror ceiling’).

The rear face of the ‘bulkhead’ wall (tare-kabe 垂れ壁) above the otoshi-kake is left unfinished (ara-kabe 荒壁, ‘rough wall’).

It is said that this inclusion in tokonoma design of an element that is ‘lacking’ is not the result of laziness or frugality, but a deliberate symbolic recognition of the sentiment expressed in the saying mitsureba kaku (満れば欠く), or in full tsuki mitsureba sunawachi kaku (月満つれば則ち虧く), ‘The full moon must (surely) wane’: perfection is futile, decay is inevitable, and all things are impermanent.

There is no picture rail (nageshi); the toko post (toko-bashira) is a squared log (men-kawa bashira); the toko-waki is tatami-floored and without shelves or cabinets.

JAPANESE MINKA LXXXV - INTERIORS 26: FORMAL AREAS 2

As covered in the previous series on minka structure, the structural logic of Japanese buildings results in two spatial zones: an inner jо̄ya (上屋, lit. ‘upper building/roof’) part, which is the area bounded within the ring of taller, inner posts (hashira 柱) called jо̄ya-bashira (上屋柱); and the geya (下屋, lit. ‘lower building/roof’), the outer, perimeter space between the jо̄ya-bashira and the ring of lower, outer posts (geya-bashira 下屋柱) that constitute the external perimeter of the building, whether in the plane of the external walls or as freestanding ‘verandah’ posts. The geya might be thought of as an infilled under-eave area, floored and walled to bring the space within the interior. The jо̄ya - geya spatial organisation is the result of the structural organisation of the building; in terms of residential architecture, it originated with the shinden (寝殿), the residential architecture of Heian period (Heian jidai 平安時代 794 - 1185) nobility.

Diagrammatic section and plan of a shinden, showing the two rings of posts that delineate the inner moya (母屋, lit. ‘mother building/roof’) space, corresponding to the jо̄ya of the minka, and the outer hisashi (庇, ‘eave’) space, corresponding to the geya.

Like the shinden, old minka often had geya on all four sides, with rows of jо̄ya posts at the boundary between the jо̄ya and the geya, as seen in the famous Furui house below.

Plan of the former Furui family (Furui-ke 古井家) residence, Hyо̄go Prefecture, a three-room layout minka, showing the jо̄ya (上屋) space (white), and the geya (下屋) space (the blue perimeter band). In this relatively primitive minka, the geya space has largely not been rationally incorporated into the plan to form closets, etc.; rather, the jо̄ya posts are for the most part freestanding in the interior spaces.

Transverse section of the Furui house, with geya shown in blue.

Longitudinal section of the Furui house, with the geya shown in blue.

In the spacious shinden, the wide geya formed a natural circulatory passageway around the inner moya; utilitarian functions like storage were taken up by other buildings in the shinden complex, so the shinden plan itself could remain architecturally ‘pure’. The narrower geya of the minka might also partially function as a circulation space, i.e. as the ‘verandah’ (engawa 縁側), but it was often used to house utilitarian elements that could practically fit within its depth; or perhaps it was rather the case that these elements evolved to fit within the geya. They included shelved cupboards (todana 戸棚), closets (oshi-ire 押入), the Buddhist alcove (butsuma 仏間), and the ornamental alcove (tokonoma 床の間 or toko 床) that is the subject of this post.

In this Muromachi period minka, the development of a tokonoma is hinted at in the utilisation of the geya space in the omote to house the Buddhist altar (butsudan), Shintо̄ shrine, and other ornamental items. Furui family (Furui-ke 古井家) house, Hyо̄go Prefecture, designated an Important Cultural Property.

The plan below is a good example of how the geya space was utilised in minka. The toko (とこ) is placed in the gable-end (tsuma 妻) geya, along with a Buddhist altar (butsudan 仏壇) and other objects related to worship and ceremony.

The geya space in this minka is more typical than that of in the Furui house in that here, as in most minka, it is partial or ‘broken’, not running the full circumference of the building. It contains ornamental alcove (toko とこ), Buddhist alcove (butsuma 卍), bath (nyūyoku 入浴), storage (shūnо̄ 収納), urinal (shо̄ben 小便), and verandah (engawa, unlabelled).

Examples like the minka above are used to argue in favour of the theory that the tokonoma has religious origins. This theory, which has become a commonly believed ‘myth’ through its presentation in works such as the Edo period Ka-oku Zakkou (家屋雑考 ‘Miscellaneous Thoughts on Houses’, 1845) by Sawada Natari (沢田 名垂, 1775 - 1845), is that the tokonoma began in the Kamakura period (Kamakura jidai 鎌倉時代, 1185 - 1333) in the shaku-ke or shakke (釈家), the residences of Buddhist priests or monks (sо̄ 僧), who would hang Buddhist art on the wall, place a thick board called an oshi-ita (押板) on the floor before it, and on the oshi-ita place the ‘three-piece set’ (mitsugusoku 三具足) of candlestick (shokudai 燭台), incense burner (kо̄ro 香炉), and vase (kabin 花瓶); this arrangement was later adopted into samurai residences (buke jūtaku 武家住宅).

Another account of the origins of the tokonoma holds that it developed as a place to appreciate the scroll art (jiku-sо̄ga 軸装画) imported from China in large volumes from the Kamakura Period onward.

A third theory is that the jо̄dan-koma (上段小間), the small raised rooms ‘within’ the zashiki, gradually simplified and shrank over time to become tokonoma, called among other names the jо̄dan-doko (上段床), that retained both the tatami-laid floor elevated a step above the zashiki and the black lacquered (kuro urushi-nuri 黒漆塗り) floor sill (kamachi 框) of its progenitor and namesake.

This third account is thought by Kawashima Chūji to be the most rational and persuasive; even today, the floor of a ‘standard’ toko is typically tatami-laid, and Kawashima writes of hearing that on certain occasions, such as tea ceremony, a distinguished guest might sit in the toko without this being considered a breach of etiquette. It is thought that later, with the development of the arts and crafts (bijutsu kо̄gei 美術工芸) in general, and the ‘ways’ (dо̄ 道) and schools (ryū 流) of tea ceremony (sadо̄ 茶道), flower arrangement (kadо̄ 華道), and incense appreciation (kо̄dо̄ 香道) in particular, that the tokonoma transformed into a place exclusively for the appreciation of interior decorative objects (shitsunai sо̄shihin 室内装飾品). Then, over the course of time and with the addition of increasingly sophisticated woodworking techniques and proportion in design, the tokonoma spread almost universally to the common minka, in the process becoming an indispensable element of the zashiki, and the one most closely associated with it.

JAPANESE MINKA LXXXIV - INTERIORS 25: FORMAL AREAS 1

After looking at the features of the ‘living room’ (hiroma 広間) and the somewhat more formal ‘drawing room’ (dei 出居) of the minka, from this week we will consider the elements typically found in, and characteristic of, the formal room proper: the zashiki (座敷).

The regular or ‘classic’ zashiki draws its design elements from the stream of the shoin-zukuri (書院造り), the residential architectural style of the Muromachi era (Muromachi jidai 室町時代, 1336 -1573) samurai (bushi 武士) class, and was furnished with a decorative alcove (tokonoma 床の間, often abbreviated to toko 床), ornamental shelves (tana 棚), and shoin (書院, a decorative ‘study' or ‘desk' alcove adjacent to the toko) as a general rule. Then a picture rail (nageshi 長押) was run around the room above the ‘door’ heads (kamoi 鴨居), with ornamental hardware (kugi-kakushi 釘隠し, lit. ‘nail hider’) attached; and ornamental panels inserted into the transom (ranma 欄間) between rooms. These panels might be kumiko (組子, geometric patterns formed with tiny pieces of timber), fretwork, or ita-ranma (板欄間), thin boards of around 12 mm thick carved with images or patterns. The ceiling ( tenjо̄ 天井) is sao-buchi tenjо̄ (竿縁天井), a ceiling of thin timber boards on exposed battens (sao-buchi 竿縁).

A zashiki seen from the ‘second room’ (tsugi-no-ma 次の間), showing ornamental alcove (toko-no-ma 床の間), ‘study’ alcove (shoin 書院), squared-log post (men-kawa bashira 面皮柱), picture rail (nageshi 長押) with ornamental ‘nail hiders’ (kugi-kakushi 釘隠し), and fine carved transom panels (ranma 欄間) between the rooms and between the tsugi-no-ma and ‘verandah’ (engawa 縁側). Yoshimura house (Yoshimura-ke 吉村家), О̄saka Prefecture, designated an Important Cultural Property.

The ‘facade’ interior elevation of a large, high-ceilinged zashiki. A good archetypal example, with: decorative alcove (tokonoma 床の間), left, displaying hanging scroll; a ‘flanking alcove’ (toko-waki 床脇), centre right, with staggered shelves (chigai-dana 違い棚) and upper cabinets (tenbukuro 天袋); a ‘study’ or ‘desk’ (shoiin 書院), right; a fine lattice transom (ranma 欄間), top left, above the entry opening; a picture rail (nageshi 長押) running around the room at head datum (uchi-nori 内法) height; an ornamental metal ‘nail hider’ (kugi-kakushi 釘隠し) on the nageshi where it meets the tokonoma post (toko-bashira 床柱); and a board and batten (sao-buchi 竿縁) ceiling.

Another zashiki, with many of the same elements shown in the zashiki above. The half-glazed shо̄ji, left, indicate this to be a relatively modern example.

In the prototypical or archetypal minka layout, there is no true formal zashiki, but even in simply-partitioned minka without a formal room, the word zashiki was sometimes used as the name of the everyday living room, elsewhere called the hiroma or dei. In the most general sense, zashiki can refer to the raised floor (taka-yuka 高床) living part (kyojū bubun 居住部分) of the dwelling, as opposed to the earth-floored utility space (doma 土間).

With rising living standards and the emergence of an economic surplus, formal zashiki came to be constructed in the houses of commoners in imitation of the upper classes, but these ‘aspirational’ zashiki were unreflective of the lifestyles of the still-impoverished farmers who installed them; often the tatami mats, so characteristic of zashiki, were taken up and left unused, indicating that in everyday use the room was being employed for less-than-formal purposes, and the inhabitants wanted to protect the valuable tatami from damage. Even if the zashiki contained a tokonoma, it might not have been used to display any of the decorative art or craft works found in the tokonoma of wealthier homes. At best there might be a hanging scroll (jiku 軸) dedicated to the god Amaterasu О̄kami (天照皇太神); at worst the tokonoma might have even fallen to the status of a place to store the tatami mats.

There were many regions in which some or all of the above-described elements of the typical zashiki were prohibited by sumptuary law from being installed in the houses of peasants, farmers, or general commoners, effectively meaning that the zashiki itself was forbidden to these social classes. But the frequency with which these regulations were issued suggests that people were constantly building these features anyway, in defiance of the law. We can sympathise with these farmers, living under an enforced and artificial austerity, wanting to beautify their homes or ‘keep up with the Joneses’, even to the point of risking presumably harsh punishments.

In constrast, important figures such as village headmen and ‘chief executives’ (肝煎 kimo-iri) were obliged to receive or entertain officials (yakunin 役人) of the samurai class in the course of their duties, so zashiki were a necessity in their homes, and facilities such as toko and tana were permitted to them. It was not unusual for such zashiki to also contain a jо̄dan no ma (上段の間), a ‘room within a room’ whose floor level is a step above the floor level of the zashiki. In addition to the toko and tana, there would normally also be a shoin, picture rail (nageshi), ‘wraparound verandah’ (mawari-en 回り縁), and perhaps a separate ‘upper toilet (kami-benjo or uwa-benjo 上便所). The mawari-en served as the formal entrance and exit for officials, doctors and others.

The zashiki in the typical four-room layout farmhouse minka occupies the upper (kami-te 上手, i.e. furthest from the doma), facade-side (omote-gawa 表側) quadrant; in hiroma-gata layouts, both upper rooms may be zashiki, called kagi-zashiki (鍵座敷), perhaps with one built as an extension off the main structure, forming the rear leg of an L-planform. A toko built against the uppermost gable end (tsuma 妻) or short-side wall is called a tsuma-doko (妻床, ‘gable-end toko); if built at the rear of the zashiki, on the partition wall with the bedroom (nando 納戸), it is called a hira-doko (平床, lit. ‘flat toko’). In the case of kagi-zashiki, the upper and lower zashiki are open to one another and together take up the whole width of the building from facade to rear, so the toko is often a hira-doko, built on the rear wall of the rear zashiki. Shо̄ji (障子, translucent paper-covered timber lattice sliding panels) or fusuma (襖, light, opaque sliding panels) were used at the boundary between two zashiki, but between zashiki and everyday living spaces such as the oe (おえ) or hiroma (ひろま), obi-to (sliding partitions of solid timber panels with a mid rail) were used, indicating that women in labour and menses (akafujou 赤不浄, lit. ‘red unclean’), those in mourning (kurofujou 黒不浄 lit. ‘black unclean’), and people of low status were not enter the zashiki without good reason.

A regular four-room layout (seikei yon-madori 整形四間取り), showing the zashiki (ざしき) in the upper (furthest from the earth-floored utility area niwa にわ) front (facade-side) quadrant, with gable-end (tsuma 妻) decorative alcove (toko とこ), called a tsuma-doko (妻床), and adjacent Buddhist alcove (butsuma 仏間). Toko and butsuma are contained in a lean-to structure outside the perimeter of the main building.

Another example of a gable-end toko (tsuma-dokoi 妻床), this time in a ‘perpendicular stagger’ (yoko-chigai-gata 横違い型) four-room layout (yon-madori 四間取り). The blind gable end (tsuma 妻) is entirely taken up with toko (とこ) and butsuma (卍) in the zashiki, and closet (oshi-ire 押入) in the rear bedroom (oku おく).

This regular four-room layout shows the minka in its original form, with a Buddhist alcove (butsuma, 卍) and cupboard (todana 戸棚) between the zashiki (ざしき) and bedroom/storage room (nando なんど); later a gable-end toko (tsuma-doko 妻床) was added as a lean-to structure, shown as a dashed line outside the exterior wall line of the main building.

This ‘wrapped hiroma’ (tori-maki hiroma-gata 取巻き広間型) layout, originally a front-zashiki three-room layout (mae-zashikisan-madori 前座敷三間取り) to which a rear kagi-zashiki (here ‘upper zashiki’ kami-zashiki かみざしき) has been added. This example solves the problem of where to place the tokonoma by omitting it.

A minka with two zashiki: the front zashiki, here called toba-no-ma (とばのま), and the rear kagi-zashiki, here called the oku (おく). The oku contains a long-side toko (hira-doko 平床), and next to it a storage closet (mono-ire ものいれ). The Buddhist alcove (butsuma, marked with swastika manji 卍), is in the room named zashiki (ざしき), which confusingly is not the formal room; at best it is semi-formal, used for courting/socialising (kousai 交際) but also for rearing silkworms (chisan shi-iku 稚蚕飼育).

Another example of a kagi-zashiki layout, this one regular (seikei 整形), with front zashiki (mae-no-zashiki まえのざしき) and rear zashiki (oku-zashiki 奥座敷). Here, the name mae-no-zashiki actually covers two rooms: the formal zashiki proper in the front upper quadrant, and a less formal ‘living room’ (ima 居間) in the front lower quadrant, adjacent to the earth-floored utility area (daidoko だいどこ). A wraparound verandah (mawari-en 回り縁) connects these three rooms; in the oku-zashiki there is a shoin, here called an akadoko (アカドコ), next to the toko, projecting out into the mawari-en.

In the postwar period, even in normal farmhouses, the tatami mats in the zashiki were left in place, but the zashiki came to function less as a formal room and more as a living room and bedroom for the elderly members of the household or for children. The tokonoma was even used as a television alcove — a utilitarian echo of the pre-modern practice of using the toko as a place to store tatami mats.

The tokonoma (床の間, left) is bare; the toko-waki (床脇) space next to the tokonoma is occupied by the Buddhist altar (butsudan 仏壇); there is no ceiling, picture rail (nageshi 長押), or separate ‘attached door heads’ (tsuke-kamoi 付鴨居); instead, grooves to take the sliding partitions are cut directly into the lintel beams.

JAPANESE MINKA LXXXIII - INTERIORS 24: LIVING AREAS 4

The oshi-ita (押板, lit. ‘pushing board’) is an ornamental element of minka, somewhat similar in appearance and function to the more well-known tokonoma (床の間), the formal ‘ornamental alcove’, but distinct from it in several ways, most immediately by its shallowness. The oshi-ita can be found in the Chūbu and Kantо̄ regions, and is commonly seen in particular in the minka of the Tama hills (Tama kyūryо̄ 多摩丘陸) region of Kanagawa Prefecture.

As the etymology suggests, the oshi-ita was originally a simple, unfixed board that sat on the floor near or against the wall, and on which an inkstone (suzuri 硯) or tray (tanzara 短皿) were placed; later by extension it came to refer to the floor board of a tokonoma or ‘study’ (shoin 書院).

There are those of the opinion that the oshi-ita is the precursor of the tokonoma, but Chūji Kawashima is inclined to think that it is of independent origin.  In minka, the oshi-ita alcove, only the depth of a post, originally had a religious function and significance: ‘prayer talismans’ (kitо̄-satsu 祈祷札 or o-fuda お札) and ritual vessels (saiki 祭器) were placed in it.  Whereas the tokonoma is installed in the formal zashiki, the oshi-ita is is not normally found there, but is located in the ‘living room’ (the hiroma ひろま or dei でい).  Within these rooms, it is commonly placed behind the yoko-za (横座), the seating position at the firepit (irori 囲炉裏) furthest from and facing the earth-floored utility area (doma 土間), and adjoining the decorative bedroom entrance (chо̄dai-gamae 帳台構え).

This oshi-ita (押板), on the left, is in its most conventional position: adjoining the formal bedroom entrance (chо̄dai-gamae 帳台構え) on the right, and behind the master’s seat (yoko-za 横座) at the firepit (irori 囲炉裏). Former residence of the Kitamura family (Kitamura-ke 北村家), Kanagawa Prefecture, now relocated to the Japan Open-Air Folk House Museum (Nihon Minka-en 日本民家園), Kawasaki Prefecture.

In terms of height, the oshi-ita stops at head datum (uchi-nori 内法) height, i.e. the height of the lintels (kamoi 鴨居) of the openings; this is in contrast to the tokonoma, which is slightly taller than the uchi-nori. 

In its position at the boundary of the hiroma or dei and the bedroom (nesho 寝所), the oshi-ita normally runs in the direction of the roof beams (hari-yuki hо̄kо̄ 梁行き方向, i.e. transverse to the long axis of the building), as in the Kitamura house above; in the Kiyomiya house below, the bedroom is on the north side of the dwelling, so the partition wall and thus the oshi-ita run in the direction of the wall beams (keta-yuki houkou 桁行き方向, i.e. parallel to the long axis of the building); the latter example is considered to be an old or antiquated style of oshi-ita. 

An archetypal and rarely-seen style of south-facing oshi-ita, located ‘up’ from the yoko-za seating position at the firepit (irori). Conventionally, the yoko-za faces the doma, which contains the entrance to the dwelling, to the east; here the doma is largely partitioned off and seemingly obscured from the living area, so a south-facing yoko-za that overlooks the unpartitioned part of the doma-living boundary, where people step up from the doma into the living area, is the most logical ‘surveillance position’.

Adjacent to the oshi-ita, and to the left of the lantern in the image, is the bedroom entrance with timber panelled sliding door(s). The oshi-ita is decorated with a flower vase and Buddhist picture scroll. Former Kiyomiya family (Kiyomiya-ke 清宮家) residence, Kanagawa Prefecture; now relocated to the Japan Open-Air Folk House Museum (Nihon Minka-en 日本民家園), Kawasaki Prefecture.

Plan of the Kiyomiya house, showing the south-facing oshi-ita (押板) and bedroom entrance to the rear (north) of the irori (炉) in the ‘living room’ (hiroma ひろま), and the earth-floored utility area (dēdoko でえどこ) to the east. Also shown are the lattice partitions (kо̄shi-mado 格子窓) and the ‘step up sill’ (agari-gamachi 上り框) between the hiroma and the dēdoko

Another view of the oshi-ita in the hiroma of the Kiyomiya house, between the entrance to the ‘drawing room’ (dē でえ) to the left and the entrance to the bedroom (ura-beya うらべや) to the right.

The examples below are both from Toyama Prefecture, where the oshi-ita is called the yoroi-tana (鎧棚, lit. ‘armour shelf’) because in the past it was adorned with armour (yoroi 鎧); the small suspended cabinets (tenbukuro todana 天袋戸棚, lit. ‘heaven bag door shelf’) are status signifiers, indicating the dwelling as the residence of a country samurai (gо̄shi 郷士).

The Kitamura family (Kitamura-ke 北村家) residence, Toyama Prefecture (not to be confused with the Kitamura house from Kanagawa Prefecture above). A high-status oshi-ita (押板), with a shelved upper cabinet (ten-bukuro to-dana 天袋戸棚) and full-width shelf (hito-moji dana 一文字棚). Designated an Important Cultural Property.

This example also has a ten-bukuro upper cabinet, but no intermediate shelf. Murakami family (Murakami-ke 村上家) residence, Toyama Prefecture, designated an Important Cultural Property.

The oshi-ita in the image below has a depth somewhat greater than the depth of the posts; in the mountainous areas of the Kantо̄ region there are districts where this type of oshi-ita is known as a kusundoko (九寸床, lit. ‘nine sun toko’).  Sun is the Japanese ‘inch’, standardised as 30.303 mm, so 9 sun is around 270mm.

On the right is a relatively deep oshi-ita, known as a kusun-doko. Former residence of the Emuki family (Emuki-ke 江向家), Toyama Prefecture; now relocated to the Japan Open-Air Folk House Museum (Nihon Minka-en 日本民家園), Kawasaki Prefecture.
