Did you know that Tatami comes in a variety of sizes?

In Japan, the size of tatami is sometimes used as a unit to indicate the size of space.

1 tatami = one jo

However, the size of the tatami is not fixed, and it changes each time depending on the size of the building.

In the olden days, tatami was used as a mat. However, tatami is currently used as a floor. Therefore, the size of the tatami must be adjusted according to the size of the floor.

Therefore, tatami vary in size depending on where they are used.

When checking the size of a house in Japan, even if the size of the room in the house is indicated as 6 tatami , the actual size of the room will differ depending on the size of the tatami.
