A shoji is a door, window or room divider used in traditional Japanese architecture, consisting of translucent sheets on a lattice frame. Where light transmission is not needed, the similar but opaque fusuma is used. Shoji usually slide, but may occasionally be hung or hinged, especially in more rustic styles.
