Fusuma (襖 or ふすま) are a type of sliding panel in traditional Japanese architecture. They consist of thick, opaque paper on a wooden frame. Fusuma are used as doors for closets (oshi-ire), and as partitions between two rooms.
Fusuma are similar to shouji, another type of sliding paper panel. The difference is that shouji are made of thin, translucent paper that lets light through.
Fusuma 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 rice paper, or have industrially printed graphics of fans, autumn leaves, cherry blossoms, trees, or geometric graphics.
