Details

The keyword for 畳 is tatami mat. This kanji refers to the traditional Japanese flooring material made of woven rush grass over a rice straw core, used as a standard unit of room measurement in Japanese architecture. By extension, it can also carry the meaning of folding, piling up, or layering, as tatami mats were historically folded and stacked when not in use. The character thus encompasses both the specific cultural object and the broader concept of repetition or accumulation.
