Fusuma
In Japanese architecture, fusuma (襖) 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 90 cm (2 ft 11 in) wide by 180 cm (5 ft 11 in) tall, the same size as a tatami mat, and are 2–3 cm (0.79–1.18 in) thick.
