fusuma

thumb|Fusuma thumb|Kin-busuma (golden fusuma) In Japanese architecture, are vertical rectangular panels which can slide from side to side to redefine spaces within a room, or act as doors. They typically measure about wide by tall, the same size as a tatami mat, and are thick. The heights of fusuma have increased in recent years due to an increase in average height of the Japanese population, and a height is now common. In older constructions, they are as small as high. They consist of a lattice-like wooden understructure covered in cardboard and a layer of paper or cloth on both sides. They typically have a black lacquer border and a round finger catch.

Historically, fusuma were painted, often with scenes from nature such as mountains, forests or animals. Today, many feature plain mulberry paper, or have industrially-printed graphics of fans, autumn leaves, cherry blossom, trees, or geometric graphics. Patterns for children featuring popular characters can also be purchased.
