You come in
at ground level.
A minka is walked, not toured. It goes earth, then a step, then board, then matting — colder to warmer, rougher to finer, public to private — and every change underfoot tells you what you are now allowed to do.
What follows is the house in that order. The Japanese terms are given once with a plain gloss, then used, because they are the names of real things and there are no English equivalents that mean the same.
Doma 土間
the earth floor
You come in at ground level, onto packed earth. The doma is not a hallway — it is the working half of the house, and in a nōka it can be a third of the whole floor plan. Threshing, hulling, pickling, tool repair, and in a hard winter the ox itself, brought inside where the family could hear it.
The floor is earth stabilised with lime and bittern and beaten hard, called tataki. It is swept, never washed. It is cold, and it is meant to be: everything done here is done in outdoor shoes.
- Floor
- Tataki — beaten earth, lime, bittern
- Footwear
- Kept on
- Also holds
- Kamado 竈, the clay cooking stove

Agarikamachi 上がり框
the step up
One timber, a single heavy beam laid along the edge where the earth floor stops and the raised floor begins. It is the most important line in a Japanese house: below it you are outside, above it you are inside, and the whole distinction is enforced by a step about fourteen sun high.
You sit on it to take your shoes off. Every visitor who is not quite a guest — the postman, a neighbour returning a tool — is received here, sitting on the kamachi with their feet still on the earth. It is a threshold you can hold a conversation on.
- Height
- Roughly 14 sun · 420 mm
- Material
- One beam, usually zelkova or chestnut
- Marks
- Where shoes come off

Yuka 床
the raised floor
Boards laid over a joisted frame, lifted clear of the ground so air moves underneath and the damp never reaches them. This is where the household lives: eats, sleeps, works in the evening, and receives anyone who matters.
Nearest the doma it is bare board — the ita-no-ma, scrubbed and hard-wearing. Further in it becomes matted. The house gets softer, quieter, and more formal the deeper you go, and nobody has to be told.
- Structure
- Boards on joists, ventilated beneath
- Nearest the doma
- Ita-no-ma 板の間 — bare board
- Deeper in
- Tatami

Irori 囲炉裏
the sunken hearth
A square cut in the raised floor, lined with clay and filled with ash, kerbed with four timbers. It heats the house, cooks the food, dries the clothes, lights the evening, and holds the family in a fixed arrangement around it.
And it keeps the building standing. There is no chimney. The smoke rises through the open frame and out through the thatch, and on the way it lays down soot on every beam and every stem of straw it passes. That soot repels insects, drives out moisture, and stops rot. A minka whose fire goes out for a decade is a minka that has begun to fail — which is why an empty one is a structural emergency and not merely a sad thing.
- Size
- Around 3 shaku square
- Lining
- Clay, filled with wood ash
- Chimney
- None — the smoke is the point

Jizaikagi 自在鉤
the adjustable hook
A hook on a cord from the beam above, with a wooden lever and counterweight that lock it at any height. Raise it to simmer, drop it to boil. Jizai means 'as one pleases' — the whole apparatus exists so a kettle can be moved through the fire's heat without touching the fire.
The counterweight is almost always carved as a fish. Two reasons, and households will give you either: a fish never closes its eyes, so it watches the fire all night; and a fish belongs to water, which is what you want hanging over the one thing that could burn the house down.
- Mechanism
- Lever and counterweight, friction-locked
- Counterweight
- Carved keyaki, usually a fish
- Made to order
- ¥94,000 — see the bench

Tatami 畳
the mats
A compressed rice-straw core, faced with woven soft rush and bound at two edges with cloth. One mat is half a tsubo — about 1.65 square metres — and rooms are not measured in metres but in mats: a six-mat room, an eight-mat room.
Which means the mat is not furnishing. It is the module. In the Kyōma system of western Japan the mat is standardised first and the posts are set around it; in the Inakama system of the east and north, including Hida, the post spacing comes first and the mats are cut to fit what is left. Two houses of 'eight mats' are therefore different sizes, and a carpenter must know which country he is in before he cuts anything.
- One mat
- ½ tsubo · 1.65 m²
- Inakama 田舎間
- Posts first, mats cut to fit — Hida
- Kyōma 京間
- Mats first, posts set around them

Shoji & Fusuma 障子・襖
the sliding screens
Shoji are a light cedar lattice faced on one side with kōzo paper. They are the outer skin: they hold weather out and let a remarkable amount of daylight through, diffused so evenly that a room with shoji on one wall has no bright side. In snow country they turn a white landscape into a lit wall.
Fusuma are the inner ones — opaque, papered both sides over a light frame, running in the same grooves. They divide rooms, and they are removable. Take the fusuma out and four rooms become one hall, which is how a farmhouse held a funeral or a wedding without owning a room big enough for either.
- Shoji 障子
- Kōzo paper on cedar lattice, translucent
- Fusuma 襖
- Papered both sides, opaque, removable
- Above them
- Ranma 欄間 — carved transoms, for air

Tokonoma 床の間
the alcove
A shallow raised recess in the wall of the zashiki, the formal room at the deep end of the house. It holds one scroll and one arrangement, changed with the season, and nothing else. Its whole function is to be the one place in a working building where something is displayed rather than used.
The post at its open edge, the tokobashira, is the only timber in the house chosen for its face rather than its strength — often left round, with the bark line still on it. The guest of highest rank is seated with their back to the alcove. They cannot see it, and everyone else can see them in front of it.
- Contains
- One scroll, one arrangement
- Tokobashira 床柱
- Chosen for its face, often left round
- Seating
- The honoured guest sits before it, back to it

Engawa 縁側
the veranda
A strip of polished board running outside the shoji and under the eave — neither in the house nor out of it. In summer the screens are slid away entirely and the engawa becomes the edge of a room that now includes the garden. In winter it is a buffer of still air.
Outside it again are the amado, heavy wooden storm shutters that slide out of a box at one end and close the house completely against a typhoon or a blizzard. Closing them at dusk and drawing them back at dawn was a daily act, and the sound of it was how a village knew a house was still lived in.
- Position
- Outside the shoji, under the eave
- Amado 雨戸
- Storm shutters, stored in a box at one end
- Summer
- Screens removed — the garden joins the room

Four sides, four ranks.
Nothing about a hearth is symmetrical except its shape. Each side of an irori has a name and a rank, and the arrangement held in nearly every minka in Japan. The fire organised the family — where you sat said who you were, and moving seats meant something had changed.
- Yokoza横座
The head of the household
Back to the wall, facing the doma
His seat and no one else's, even when he is out. A guest offered it would refuse. From here he sees the entrance, so he sees who comes in before they see him.
- Kakaza嬶座
The wife
The kitchen side
Nearest the pots, the stove, and the water. She controls the fire itself — the ash, the charcoal, and the height of the kettle on the hook. Practically, the most powerful seat at the hearth.
- Kyakuza客座
The guest
Opposite the kakaza
Set so the guest faces the fire with the household's food side across from him and the head of the house to his side. He is warmed first and served first, and he is never seated with his back to the door.
- Kijiri木尻
Children, apprentices, the lowest-ranking
The wood's end
Literally 'the end of the wood' — the side the firewood is fed in from, so it takes the smoke, the sparks, and the traffic. You sat here until someone decided you no longer had to.
