What is Jo?

The jo is a Japanese unit of area based on the size of one tatami mat, standardized at 1.62 square meters for real estate purposes by the Japan Fair Trade Council. However, actual tatami dimensions vary by region: the Kyoto-style kyoma is about 1.82 m², the Tokyo-style edoma is about 1.55 m², and the Nagoya-style chukyo-ma is about 1.66 m². In Japanese housing, room sizes are almost always described in jo (for example, "a 6-jo room" or "an 8-jo living room"). This unit provides an intuitive sense of room size that is deeply rooted in Japanese residential culture.
