In traditional Japanese architecture, a shōji (障子) is a door, window or room divider consisting of translucent paper over a frame of wood which holds together a sort of grid of wood or bamboo.
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).
