Futon: How Japanese Bedding Works

A mattress that folds into a closet by day and a comforter that airs on the balcony: the Japanese bedding routine, explained.

Quick answer: A traditional Japanese futon is a set of bedding laid directly on the floor, usually on tatami. It has a thin mattress called a shikibuton, a comforter called a kakebuton and a pillow, and it is folded and stored in a closet each morning. The system saves floor space, keeps rooms flexible, and works best with regular airing to prevent moisture.

What a futon set includes

In Japan, the word futon refers to a full set of bedding rather than a Western-style frame with a mattress. The base layer is the shikibuton, a thin padded mattress that lies on the floor. Over it goes the kakebuton, a quilted comforter that can be filled with cotton, wool, down or synthetic fibers. A sheet and a cover protect both layers and are washed regularly. The pillow, called a makura, comes in various types. Some are filled with buckwheat husks, which mold to the head and stay cool, and others use tubes, beads or soft fibers.

People choose pillows by height and firmness, and shops let you test several. Because the pieces are separate, a household can adjust the combination to the season. Extra layers go on in winter, and lighter ones appear in summer. A thin layer called a mattress pad or a wool underlay sometimes goes beneath the shikibuton for extra warmth and cushioning. Duvet covers have openings along one edge, and the filling can be removed for laundering when the cover is the only part that needs cleaning.

Why the floor works in a Japanese room

Traditional Japanese homes have tatami rooms that serve many functions during the day. The same space may be used for meals, relaxation and guests, and at night it becomes a bedroom. Bedding that can be folded away makes this flexibility possible. Tatami mats provide a slightly cushioned, breathable surface. They are made of rice straw covered in woven rush, and the material helps absorb some moisture and gives the floor a pleasant scent. Sleeping on tatami, with a thin futon, is a long-standing habit.

The system is especially practical in small homes. Without a bed frame, the room stays open, and cleaning is simple. Many apartments with just one or two rooms rely on this arrangement. Even in modern apartments without tatami, people may lay out a futon on a wooden floor with a protective mat underneath. The method suits small rooms, and some foldable styles allow the same room to serve as a living area during the day.

The daily routine

In the morning, the bedding is folded or rolled and placed in an oshiire, a deep closet with sliding doors. The sheets may be left on or removed, depending on the household. The room returns to its daytime use, and the floor is ready for meals or other activities. In the evening the process reverses. The futon is pulled from the closet and laid flat, the comforter is placed on top and the pillow is positioned. Setting out bedding is quick, and many people find the ritual relaxing.

If you live with a futon, a few habits help. Let the bedding rest uncovered for a short time each morning, and avoid leaving it on the floor all day, since moisture can build up beneath it. Guests staying in a home are often given a futon, and hosts take pride in providing clean sheets and a thick comforter. Sleeping in this way can feel cozy once you get used to the low position and the sense of being close to the floor.

Airing and caring for the bedding

Regular airing is the most important maintenance task. On sunny days, Japanese households hang their futon over a balcony railing or a pole to air in the sun. This warms the filling, reduces moisture and helps keep the bedding fresh. Many people do this once or twice a week in good weather. Beating the futon with a stick, once common, can damage the filling, so many people now use a soft brush or a vacuum with an attachment.

Futon dryers, which blow warm air through the bedding, are popular in homes without a sunny balcony. Covers and sheets can be washed at home. For the main pieces, check the care tag, and consider professional cleaning services or large coin laundries that handle bulky items. Do not wash a futon in a regular machine unless the label permits it.

Humidity and mold

Japan has a humid climate, particularly in summer and the rainy season, so moisture is a real concern. A futon left on the floor for long periods can trap dampness and encourage mold. For this reason, people use several methods to keep bedding dry. One is a slatted bed board, known as sunoko, which lifts the futon above the floor and allows air to circulate.

Another is a moisture-absorbing sheet, which can be dried in the sun. A dehumidifier and good ventilation help as well. If you notice a musty smell or spots, air the bedding promptly and check the floor underneath. Early attention prevents bigger problems and keeps the futon comfortable. In winter, condensation near cold walls can also dampen bedding, so leaving a small gap between the futon and the wall allows the air to move.

Sleeping on a futon in a ryokan or guesthouse

At a ryokan, the staff typically prepare futon in your room while you are at dinner or out for a bath. You will return to find the bedding laid out on the tatami, often with a yukata set on top. The arrangement is simple, comfortable and part of the experience. If you prefer a firmer or softer bed, ask the staff for an extra layer. Many inns can provide a second mattress or a thicker comforter. Pillows may also be available in different styles.

In the morning, you generally leave the bedding as it is, and the staff will handle it. Check the inn's instructions in case they have a different preference, and keep your belongings off the bedding to avoid creasing it. Guesthouses and hostels may also use futon, especially in tatami dormitories. If you have back concerns, ask whether a firmer or thicker option is available, and bring any small items you need for comfort, such as a favorite pillow or eye mask.

Buying a futon and modern alternatives

Futon can be bought at home goods stores, department stores and online shops. Prices vary widely depending on the filling and size, so compare options. Standard Japanese sizes include single, semi-double and double, and dimensions are slightly different from Western beds, so measure before you buy. Modern alternatives include thick folding mattresses and mattress toppers that can be used on the floor or on a bed frame.

These are popular with people who want the space-saving benefits without the full routine of airing. When shopping, think about your climate, your space and your sleeping habits. Cotton fillings are heavy but firm, wool is breathable, and synthetic fillings are light and easy to wash. Many stores allow you to lie down on a sample before buying, and staff can explain the differences between fillings, thicknesses and care needs.

Frequently Asked Questions

Is a futon comfortable?

Many people find it comfortable, especially on tatami. The thin mattress is firmer than a Western bed. If you prefer more cushioning, add a topper or a second layer, and choose bedding suited to your body. Beginners often add a mattress topper under the shikibuton, and choosing a firmer or softer filling gives control over how the bed feels through the night.

How often should a futon be aired?

In good weather, once or twice a week is common. Hang it in the sun for a few hours, then bring it in before the air cools. In humid or rainy periods, use a dryer or dehumidifier. A cover with a zip or buttons makes washing easy, and a moisture-absorbing sheet beneath the futon helps in the rainy season when the air stays damp.

Can a futon be used on a bed frame?

Yes, although it is designed for the floor. On a frame, choose a slatted base that allows air to circulate. Some modern futon are made thicker for this purpose. A slatted base or sunoko board is a good option, and choosing a thin futon avoids stacking too many layers on top of a mattress.
