-Tatami-

English Definition:
Woven straw mats used as flooring in traditional and modern Japanese-style homes

In the late 8th century A.D., tatami mats were used as moveable, isolated pieces, the size of which dictated social rank. By the 14th century, floors were entirely covered with tatami mats. Today, the tatami is a common unit of measurement when discussing home and apartment floor space in Japan. One tatami is equal to about 3 feet by 6 feet.

Note: "Tatami mats" relates to the craft, Tategu, Japanese home interior fixtures, such as shoji screens, panels and doors, as well as fusuma sliding doors.
