Japanese Japanese room

Japanese rooms are categorized into Wado and Yoko

Wado is a traditional Japanese room with a tatami matting floor, which is called a bed in Japanese, so a tatami matting floor is called a tatami bed

Yoko is the same as in China, where there are regular tiles, but there are also carpets, wooden floors, etc.

Nowadays, there are very few purely Wado rooms in Japan.

There are very few Japanese-style rooms left in Japan, and most families use yoko (Japanese tatami mats)

Tatami mats are made of straw and are similar to straw mats in Japan, but much smaller and thicker, so it takes a lot of straw to make a Japanese-style bed

The tatami mats are a fixed size, and if you convert them to square meters, they're a lot smaller. If you convert it to square meters, it's 1.6562 m2

So a tatami mat is an old Japanese unit of measurement for the size of a room.
