Frequently Asked Questions
What is a tsubo and how big is it?
A tsubo (坤) is a Japanese unit of area equal to approximately 3.306 m² (about 35.58 ft²). It is nearly identical to the Korean pyeong. One tsubo equals 2 tatami mats in the Nagoya/standard (Chūkyō-ma) size.
What is the difference between tatami sizes across Japan?
Tatami mat sizes vary by region: Kyō-ma (Kyoto, 191×95.5 cm), Chūkyō-ma (Nagoya, 182×91 cm), Edoma/Kantō-ma (Tokyo, 176×88 cm), and Danchi-ma (public housing, 170×85 cm). When comparing apartments, knowing the tatami standard used is important.
Why are Japanese apartments measured in tatami mats?
Tatami (畳) has been the traditional flooring in Japanese homes for centuries, so room sizes are naturally expressed in mat count. A typical room might be 6-jō (6 mats, about 9.9 m²) or 8-jō (8 mats, about 13.2 m²). This convention persists even in modern apartments with non-tatami flooring.
