The size of a Japanese building is indicated by the number of tatami.

One tatami exists as a reference grid, and several tatami are lined up to represent the area (4 tatami, 6 tatami, 10 tatami, etc.).

One tatami is said to be about the same size as one adult Japanese man, so the space is set by the number of tatami mats.

In Japan, it is a book that clearly shows that measure and constructions value the human unit.
