Japanese Futon: The Traditional Floor Bed

Every morning in millions of Japanese homes, a thick padded mattress gets folded, aired out on a balcony railing, and tucked into a closet — and every evening, the same room that served as a living space all day becomes a bedroom again in a matter of minutes.

What is a Japanese futon? A traditional Japanese futon set consists of a shikibuton, a firm padded mattress placed directly on the floor, and a kakebuton, a lighter comforter-style cover. It has no frame, and unlike the folding sofa bed sold abroad as a “futon,” it is folded and stored in a closet each morning.

The futon, Japan’s traditional floor bedding, persists alongside — and often instead of — the Western-style bed frame that has become common in newer homes, and the reasons behind its staying power go well beyond simple tradition.

What a Japanese Futon Actually Is

A traditional Japanese futon set consists of a shikibuton, a firm padded mattress placed directly on the floor, and a kakebuton, a lighter comforter-style cover, distinct from the Western “futon” often sold internationally as a folding sofa-bed frame with a thick cushion. The genuine Japanese version has no frame at all — it rests directly on tatami or hardwood flooring and is designed specifically to be folded up and stored away during the day rather than left permanently assembled.

This portability is the core functional difference from a Western bed, and it’s the feature that makes everything else about futon culture — the multi-purpose room, the daily airing ritual, the storage habits — possible in the first place.

A Brief History of the Futon

Sleeping on padded bedding placed on the floor has roots stretching back centuries in Japan, but the futon as widely recognized today became commonplace during the Edo period, as cotton production expanded and made padded bedding more accessible to ordinary households rather than remaining a luxury reserved for the wealthy. Before this, many people slept on simpler straw mats with far less cushioning.

The format proved well suited to Japanese housing conventions that had already developed around flexible, reconfigurable rooms, and the futon’s practical advantages — compact storage, no fixed furniture commitment — meant it remained the dominant sleeping arrangement for the vast majority of Japanese households well into the 20th century, with Western-style beds only becoming a mainstream alternative in the postwar decades.

Buying and Maintaining a Futon Today

Modern futon sets range from basic, affordable cotton-filled versions to higher-end options incorporating synthetic fills designed for better insulation and moisture control, sold at dedicated futon and bedding shops as well as general home goods retailers. A supplementary mattress topper is common with thinner futons to add extra cushioning against the hard floor beneath, particularly for anyone finding the traditional firmness too much on its own.

Regular replacement is recommended more frequently than a Western mattress, since the padding compresses and loses its supportive quality with continuous daily folding and use, and many households replace their futon every few years rather than expecting the same multi-decade lifespan often associated with a quality Western mattress and frame.

The Multi-Purpose Room Logic

Because a futon can be completely put away each morning, a single room can function as a bedroom at night and a living or dining space during the day, a genuinely practical advantage in Japan’s characteristically compact housing, where square footage carries a real cost premium. This flexibility is closely tied to the same design logic behind the traditional washitsu tatami room, which was built from the outset to be reconfigured throughout the day rather than dedicated permanently to a single function.

A Western bed frame, by contrast, permanently commits a room to being a bedroom around the clock, a tradeoff that makes far more sense in housing with generous square footage to spare than in a compact Japanese apartment where every room needs to earn its keep.

The Daily Airing Ritual

Airing out a futon regularly, ideally daily when weather permits, is considered essential maintenance rather than an optional chore. Hanging the mattress over a balcony railing or a dedicated futon stand in direct sunlight helps prevent moisture buildup, since a futon in direct contact with the floor is more prone to dampness and mold than a bed frame that allows air circulation underneath.

Specialized futon-drying appliances have become common in households without convenient outdoor airing space, using heated air blown through an attachment placed under the futon, a modern technological workaround for apartments — particularly upper-floor units without a suitable balcony — where traditional sun-airing isn’t practical.

Why Beds Have Also Become Common

Despite the futon’s continued presence, Western-style bed frames have become genuinely widespread in Japan, particularly among younger generations and in newer housing built with less multi-purpose room flexibility in mind. Beds eliminate the daily folding routine entirely, and growing awareness of potential health considerations — easier entry and exit for older or less mobile individuals, in particular — has pushed adoption further among Japan’s aging population specifically.

Many households today use a hybrid approach: a bed frame in a bedroom used exclusively for sleeping, while a separate tatami or flexible room, if the home has one, retains futon bedding for guests or occasional overflow use — a practical middle ground between full tradition and full Western-style conversion.

How to Fold and Store a Futon

Air it first. Remove the comforter and hang or spread the bedding so that body heat and moisture can escape.
Fold the kakebuton (comforter) neatly in three.
Fold the shikibuton (mattress) in three as well, and stack it with the comforter.
Store it in the closet (oshiire), ideally on a slatted shelf or a breathable mat to prevent mold.
Open the closet door sometimes so that the air circulates, especially in damp seasons.

Keeping a Futon Fresh and Free of Mold

Air the futon in the sun when the weather is dry, and avoid doing it when it is raining or very humid
Instead of beating it, which can damage the fibers, use a vacuum with a futon attachment or a soft brush
Use a washable sheet over the mattress and a cover over the comforter, and launder them often
Put a slatted mat (sunoko) or a moisture-absorbing sheet under the futon, especially in humid months or on hard floors
Use a futon dryer or a dehumidifier in the rainy season when outdoor airing is not possible

Futon or Bed? Which Suits You

Futon advantages: saves space, because the room is free during the day; firm support; easy to air and wash; works well in a tatami room
Futon drawbacks: daily folding and airing take effort; getting up from the floor can be harder for some people; it needs storage space and good ventilation
Bed advantages: no daily setup, easier to get in and out of, no storage needed
Bed drawbacks: takes space all day, and costs more to move or replace

Buying a Futon in Japan

You can buy futon sets at home-furnishing stores such as Nitori and Muji, bedding shops, and online. Prices range from a few thousand yen for a basic set to tens of thousands for higher-quality materials. Japanese sizes differ from Western ones, so check the dimensions: a Japanese single (shinguru) is roughly 100 centimeters wide and about 200 centimeters long, and the larger sizes include semi-double and double. If you are moving into your own place, unfurnished apartments often mean you will have to buy bedding yourself. The tatami room washitsu is the traditional place to put it, and the daily routine fits well with laundry and drying habits in a Japanese apartment.

Frequently Asked Questions

Do Japanese people still sleep on futons?

Many do, though Western-style beds have become increasingly common, especially among younger generations and in newer housing. Futons remain popular partly because they let a room serve multiple purposes throughout the day.

Why do you need to air out a Japanese futon?

A futon placed directly on the floor is more prone to moisture buildup than a bed frame with underneath air circulation, so regular airing, either in sunlight or with a futon dryer, helps prevent dampness and mold.

What’s the difference between a Japanese futon and a Western futon?

A traditional Japanese futon is a padded mattress and cover placed directly on the floor with no frame, designed to be folded and stored daily. The Western “futon” typically refers to a folding sofa-bed with a frame, a different product despite sharing the name.

How often should you replace a Japanese futon?

More often than a Western mattress, typically every few years, since the padding compresses with continuous daily folding and use and gradually loses its supportive quality.

How do you fold a futon?

Fold the comforter and the mattress each in three, stack them, and put them in the closet. Air the bedding first so that moisture does not stay trapped.

How often should you air a futon?

Ideally every day when the weather allows, or at least a few times a week. In humid seasons use a futon dryer or dehumidifier, and avoid airing on rainy days.

Can you use a futon on a bed frame?

Yes, a Japanese futon can be placed on a slatted bed frame. This adds air circulation, but you lose the space-saving benefit of folding it away.

Where can I buy a futon in Japan?

Furniture and home stores such as Nitori and Muji sell them, as do specialized bedding stores and online shops. Check the size, because Japanese single and double sizes are smaller than many Western equivalents.

Why Many Households Keep the Futon

The continued relevance of the futon, even as beds have become mainstream, reflects the same efficiency-minded thinking that runs throughout Japanese domestic design — treating living space as something that should flex to meet different needs throughout the day rather than being permanently divided into single-purpose rooms.

Whether a household ultimately chooses a bed, a futon, or some combination of both, the underlying logic behind the futon’s persistence says something real about how thoughtfully Japan has historically approached the challenge of living well in limited space.
