shouji
Shouji (障子) are a type of door, window, or room divider in traditional Japanese architecture. They consist of thin, translucent paper on a wooden lattice frame. The paper is thin enough to let light in, but not to see through.
Shouji can be used as sliding doors or as windows. Sometimes, shouji panels may include a small glass window to see through.
Shouji are similar to fusuma, another type of sliding paper panel. The difference is that fusuma are made of thick, opaque paper that doesn't let light through.
