The Futon: Japan’s Traditional Sleeping System
The Japanese futon is not the fold-out sofa-bed associated with the word in the West. It is a system: a thick cotton mattress (shikibuton) laid directly on the tatami floor, topped by a quilted comforter (kakebuton) and supported by a firm cotton pillow (makura). The setup is designed for a specific relationship between the sleeper and the floor — lower, cooler, and with a freedom of movement that the raised Western bed does not provide. For many visitors to Japan, sleeping on a futon in a tatami room is one of the most memorable experiences of their trip.
How the Futon System Works
The shikibuton (bottom mattress) is typically 6–8cm thick, filled with cotton batting, and considerably firmer than a Western mattress. It does not sit on a frame — it is placed directly on the tatami surface, which itself provides gentle give. The kakebuton (top comforter) is lighter in summer and thicker in winter; many inns provide both and allow guests to layer them. Traditional makura (pillows) are quite firm compared to Western pillows; modern Japanese households often supplement with softer alternatives.
At a ryokan, futon are typically set up by staff while guests are at dinner, and removed in the morning. The act of preparing and putting away bedding (futon no shitatame and katazuke) is a small but real part of traditional Japanese domestic rhythm.
Futon in Traditional Architecture
The futon system evolved in direct relation to Japanese architecture. Tatami rooms serve multiple functions during the day — dining room, sitting room, reception space — and the futon allows the sleeping function to be added and removed as needed. Closets in traditional Japanese rooms (oshi-ire) are specifically designed to store folded futon during the day: a wide, deep cupboard behind sliding doors, typically with two levels, the upper for the kakebuton and the lower for the shikibuton.
This multi-use flexibility of the tatami room reflects the spatial efficiency that characterised traditional Japanese houses where a single room might serve every function in daily life.
Futon Care: Airing and Maintenance
Traditional futon maintenance involves airing (futon-hoshi): hanging the futon over a railing or balcony in direct sunlight on dry days. The sunlight kills dust mites, the UV sterilises the filling, and the evaporation removes moisture absorbed overnight. The practice is so common that Japanese balconies are typically designed with horizontal rails specifically for futon airing, and the sight of futon hanging from apartment balconies is one of the most ordinary scenes of Japanese residential life.
Cotton futon are beaten (tataku) with a flexible rod or racquet to redistribute the filling and remove dust. Professional futon shops offer re-fluffing services in which the cotton is removed from the cover, cleaned, separated, and re-sewn into a new cover.
Modern Futon Culture
Many contemporary Japanese households sleep on Western-style beds, particularly in urban apartments. Futon persists most strongly in traditional homes with tatami rooms, at ryokan, and in the guest rooms of family homes. Futon retailers (such as Nishikawa, Japan’s oldest futon manufacturer, established 1566) sell across a wide quality range from polyester-filled economy versions to hand-stitched premium cotton that will last decades. Department store futon sections — particularly in autumn before the cold season — display an extraordinary variety, and watching the testing and comparison process among customers is a small window into Japanese domestic priorities.
