Japanese room with sliding shōji doors and tatami flooring
In traditional Japanese architecture, a shōji(Japanese: 障子) is a door, window or room divider consisting of translucent paper over a frame of wood which holds together a lattice of wood or bamboo. While washi is the traditional paper, shōji may be made of paper made by modern manufacturing processes; plastic is also in use.
Shōji doors are often designed to slide open, and thus conserve space that would be required by a swinging door.
They are used in traditional houses as well as Western-style housing, especially in the washitsu (Japanese-style room). In modern construction, the shōji does not form the exterior surface of the building; it sits inside a sliding glass door or window.
