What a tokonoma is, and what it is not
The tokonoma (床の間, display alcove) is a recess set into the wall of a washitsu (和室, Japanese-style room). It is usually one ken wide (about 1.8 m), roughly 80 cm deep, and its floor sits a few centimetres above the surrounding tatami. It holds a kakejiku (掛軸, hanging scroll), often a seasonal flower arrangement, and sometimes an incense burner or a single ceramic piece. That is all.
The point is emptiness. A tokonoma displays one idea at a time, changed with the season, and the surrounding space is what gives that object weight. This is why the three things Western visitors instinctively do are all wrong: putting a television in it, using it as a bookcase, or standing in it to hang a picture.
Where it comes from
The alcove descends from shoin-zukuri (書院造, study-room style), the architecture of warrior residences and Zen temples formalised from the fifteenth century onwards. It began as a place to display a devotional scroll and became, over time, the formal heart of the reception room. The main styles of Japanese architecture each treat it differently, and the tea-house tradition deliberately made it smaller and rougher.
Where you actually find one today
You will find a tokonoma in most houses built before the 1990s that have a proper reception room, in nearly every kominka (kominka, traditional country house) and machiya (machiya, wooden town house typical of Kyoto), and in a shrinking share of new builds. The formal washitsu has been in slow decline in Japanese new construction for decades, pushed out by open-plan living rooms and by the cost of the joinery. That decline is precisely why the alcove now concentrates in the older stock: the same stock listed in our catalogue of Japanese houses for sale.
Anatomy and vocabulary of a tokonoma
Six or seven named parts make up a full alcove. Knowing them lets you read a listing, talk to a carpenter, and judge quality in about thirty seconds at a viewing.
| Part | What it is | What to look at |
|---|---|---|
| toko-bashira (床柱) | The feature post at the open corner of the alcove, often a whole trunk kept in its natural shape | The signature piece. Species, figure and finish tell you the original budget |
| toko-gamachi (床框) | The horizontal front beam that closes the raised floor, frequently lacquered | Splits, lifted lacquer, water marks at the ends |
| tokoita (床板) | The floor of the alcove: a single wide board, or a tatami mat | A single board without joints is a sign of quality |
| otoshi-gake (落し掛け) | The small lintel across the top of the opening | The first place a roof leak shows as a brown stain |
| tokowaki (床脇) | The bay beside the alcove, holding shelves and a cupboard | Present in formal rooms, absent in simplified ones |
| chigaidana (違い棚) | The staggered display shelves inside the tokowaki | Fine joinery, and expensive to repair badly |
| tsukeshoin (付書院) | The built-in writing bay next to the window | Rare, and a sign of a genuinely formal room |
The toko-bashira deserves its own paragraph
The post is the one element a carpenter could not fake cheaply. A polished keyaki (欅, zelkova) trunk, a cedar pole with its bark left on, a twisted pine or a length of black persimmon each cost real money and were chosen deliberately. When you see a plain square post of ordinary softwood, painted or veneered, you are looking at a token alcove fitted into a mass-produced post-war house. That single observation often tells you more about the build quality of the whole property than the listing does. Our guide to reading a Japanese property listing covers the notation traps that go with it.
The four types, from the most formal to the most rustic
Not every alcove is a full formal one. The type sets the register of the room, and it also decides how easy the alcove is to modify.
| Type | Floor | Register | Typically found in |
|---|---|---|---|
| hondoko (本床) | Raised, with a lacquered front beam and a wide board | The most formal, complete with shelves and writing bay | Large pre-war houses, temple guest rooms |
| fumikomi-doko (踏込床) | Level with the tatami, no front beam | Simplified, sober | Post-war houses, small reception rooms |
| oribe-doko (織部床) | No recess at all: a decorative board fixed to the wall | Minimal, tea-house spirit | Small rooms, later conversions |
| tsuri-doko (釣床) | Suspended: only the lintel and a hanging point | The lightest form, for a scroll alone | Tea rooms, tight spaces |
Practical consequence: a tsuri-doko or an oribe-doko can be undone in an afternoon, because nothing structural is involved. A hondoko with its shelving bay is joinery, and taking it out properly means a carpenter, not a demolition crew.
The seat of honour: the etiquette that still applies
In a Japanese room, the alcove fixes the geography of politeness. The seat closest to the tokonoma is the kamiza (上座, upper seat), the place of the most senior guest. The seat nearest the door is the shimoza (下座, lower seat), taken by the host or the most junior person. This is not folklore: it is still applied in ryokan dining rooms, in temple reception rooms and in formal meetings.
Three rules that never change
- You do not step into the alcove. Not to hang a scroll, not to clean, not to take a photograph. Work from the edge, kneeling.
- You do not store anything there. No suitcase, no bag, no coat, no television. The alcove is not a surface.
- The guest of honour sits with their back to it. Counter-intuitive to a Western eye, and the point is that the guest is framed by it, not looking at it.
If you intend to run the house as a short-term rental, this is worth a line in your house manual. Guests who understand the alcove treat it carefully; guests who do not will put a suitcase in it on the first evening.
What a tokonoma tells you about the house you are viewing
This is the part no architectural glossary covers, and it is the reason to look at the alcove first when you walk into a washitsu.
It dates the house, and reveals the original budget
A complete hondoko with a tokowaki, staggered shelves and a chosen post means the house was built with a proper reception room by an owner who paid for joinery. A shallow, level alcove with a plain post in a 1975 tract house means the builder ticked a box. Between the two lies most of the Japanese stock, and the alcove is a fast proxy for how the rest was built.
It shows you water before anywhere else does
The alcove sits under the roof structure and against an outside wall in many plans, and its finishes are absorbent: clay plaster, paper, untreated wood. A brown halo on the otoshi-gake, a dark tide line at the foot of the post, or clay that has blistered at the back of the recess are early signs of a leak or of rising damp, often visible long before the ceiling stains. Photograph them, and read our article on damp and mould in Japanese houses before you make an offer.
It tells you whether the room was heated
A washitsu is usually the coldest room in a Japanese house: single-glazed, uninsulated, and closed off for most of the year. If the alcove smells musty and the post feels damp to the back of your hand, the room has been shut and unheated for a long time. That is a normal state for an akiya (akiya, empty house), not a defect in itself, but it should send you straight to the question of insulating a Japanese house.
It warns you when the post is structural
In most post-war houses the toko-bashira is decorative. In older kominka and in some machiya it is a genuine load-bearing post of the frame, dressed to be seen. Never assume. Removing a structural post without replacing its function is the single most expensive mistake available in this part of the house, and it is one that a Japanese carpenter will spot in a minute and a foreign buyer will not.
The alcove is not the only fixture that reads like a diagnosis. The sunken hearth, or irori (囲炉裏) tells you when the house stopped being heated the traditional way, and it is usually still there under the floorboards.
Keep it, adapt it or remove it: options and real costs
Three honest options, with orders of magnitude. Figures are estimates for a standard one-ken alcove, based on typical craft rates, and they vary widely by region and by the state of the room. Treat them as a range to budget against, not as a quotation.
| Option | What it involves | Estimated cost | Reversible |
|---|---|---|---|
| Clean and refresh | Wash and wax the post, re-paper the back wall, refinish the board | ¥60,000 to ¥150,000 (about $380 to $960) | Yes |
| Repair the clay wall | Re-face the plaster inside the recess, patch the beam ends | ¥80,000 to ¥200,000 (about $510 to $1,280) | Yes |
| Convert into a closet | Fit shelves and sliding doors, keep the opening and the post | ¥150,000 to ¥400,000 (about $960 to $2,560) | Largely |
| Remove completely | Close the recess, continue wall, floor and ceiling | ¥300,000 to ¥700,000 (about $1,920 to $4,490) | No |
The case for keeping it
Keeping and cleaning an alcove is the cheapest line in any renovation of a traditional house, and it is the one that most changes how the property photographs. If the house is going to be let to travellers, or resold to a buyer who came looking for a traditional house in the first place, removing the only genuinely Japanese feature of the main room is an odd way to spend money. Our breakdown of machiya and kominka renovation costs puts these figures next to the items that really drive a budget: roof, frame, seismic work and plumbing.
The case for adapting it
Storage is the honest weak point of an old Japanese house, and converting the alcove into a fitted cupboard is a common Japanese solution, not a foreign heresy. Done well, it keeps the post and the opening visible and is reversible.
Worked example: a 1974 house in Wakayama, tokonoma included
A wooden house from 1974 in inland Wakayama, listed at ¥4,800,000 (about $30,800). It has a six-mat washitsu with a fumikomi-doko: level floor, plain post, clay walls marked at the back of the recess.
| Item | Yen | Approx. USD |
|---|---|---|
| Asking price | ¥4,800,000 | $30,800 |
| Purchase costs, capped at 6% | up to ¥288,000 | up to $1,850 |
| Total to acquire | about ¥5,088,000 | about $32,600 |
| Option A: clean and refresh the alcove | ¥120,000 | $770 |
| Option B: convert it into a closet | ¥260,000 | $1,670 |
| Option C: remove it entirely | ¥520,000 | $3,330 |
Reading of the case: the marked clay at the back of the recess is the first thing to explain, because it is a symptom, not a finish problem. If it comes from a roof leak, the roof is the budget line that matters and the alcove is a detail. If it comes from a closed, unheated room, ventilation and insulation come first. In both cases option A becomes sensible only once the cause is dealt with, which is exactly the order of operations a survey should establish before the offer, not after. Total purchase costs stay at or under 6% of the price, which is the rule across Japan and one of the good surprises of buying there.
Note that buying this house gives no residence right of any kind: property ownership and immigration status are entirely separate in Japan. Nor is a mortgage realistic here, since Japanese home loans are in practice reserved for people who both live and work as employees in Japan. A purchase like this one is a cash purchase, and our complete guide to buying a house in Japan sets out the full sequence.
Common mistakes and expert advice
Five mistakes we see repeatedly
- Treating the alcove as dead space to be reclaimed. It is about 1.4 m2. Removing it rarely changes how the room is used, and it always removes the reason the room is interesting.
- Assuming the post is decorative. In a kominka it may be carrying load. Ask before you plan, and get it confirmed in writing.
- Sanding or varnishing the toko-bashira. The patina is the value. A modern varnish on an old zelkova post is irreversible and reads as damage to any Japanese buyer.
- Fixing the stain instead of the leak. Re-papering over a water mark hides the evidence for one season and costs you the roof anyway.
- Filling it. A crowded alcove is not a decorated alcove. One scroll, one arrangement, nothing else.
Advice from viewings
- Photograph the alcove from the room and then close up on the lintel, the base of the post and the back corners. Those four images answer most later questions.
- Run the back of your hand over the post and the clay at knee height. Cold and damp is information.
- Ask when the room was last used and last heated. The answer explains most of what you are seeing.
- If you plan a minpaku (minpaku, short-term rental under the private lodging law, capped at 180 nights a year), keep the alcove. Japan received a record 42.7 million visitors in 2025, and a genuine washitsu with a well-kept alcove is what makes a rural listing photograph differently from every apartment in the same town.
- Look at how alcoves are treated in the machiya we track: our machiya for sale and kominka for sale pages, and the Kyoto prefecture guide, are the fastest way to compare a dozen of them.

Conclusion: a small alcove that describes the whole house
A tokonoma is 1.4 square metres that cost almost nothing to keep and tell you a great deal: when the house was built, how carefully, whether it has taken water, and whether the room has been lived in. Learn its seven parts and you can read a washitsu faster than the listing describes it.
Before you decide anything about the alcove, deal with the cause of any mark you find in it, confirm whether the post carries load, and only then choose between keeping, adapting and removing. In the great majority of the traditional houses we see, keeping it is both the cheapest option and the one that protects the resale story.

Frequently asked questions
What is a tokonoma used for?
It is a display alcove, not storage. It holds one hanging scroll and usually a seasonal flower arrangement, changed through the year. Nothing practical is kept there, and the empty space around the object is part of the effect.
Can you remove a tokonoma?
Usually yes, but check the corner post first. In post-war houses it is decorative and the alcove can be closed or turned into a cupboard. In a kominka the post may be part of the load-bearing frame, in which case removal is a structural job.
Is it rude to step into a tokonoma?
Yes. You never stand or step inside the alcove, even to hang a scroll or to clean it. The work is done kneeling from the edge, and nothing is stored or placed there.
What is the post in the corner of a tokonoma called?
The toko-bashira. It is often a whole trunk kept in its natural shape, in zelkova, cedar, pine or black persimmon. Its species and finish are the clearest sign of how much was spent on the original build.
Do modern Japanese houses still have a tokonoma?
Fewer and fewer. The formal Japanese-style room has been in long decline in new construction, so alcoves are now concentrated in houses built before the 1990s, and in traditional kominka and machiya.
Where does the guest of honour sit in a room with a tokonoma?
In the kamiza, the seat nearest the alcove, with their back to it. The host or the most junior person sits at the shimoza, closest to the door. The rule still applies in ryokan and formal meetings.
How much does it cost to convert a tokonoma into storage?
Budget roughly 150,000 to 400,000 yen (about $960 to $2,560) for shelves and sliding doors that keep the opening and the post visible. Complete removal, with wall, floor and ceiling made continuous, runs higher.
Does a tokonoma add value to a Japanese house?
It rarely adds measurable value on paper, but a well-kept alcove strongly affects how a traditional house photographs and sells, and it matters to the buyers and travellers who are looking for a Japanese house in the first place.
