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.

What is Are?

The are is a unit of area equal to 100 square meters, or a square 10 meters on each side. It was introduced as part of the metric system during the French Revolution. While less commonly used today than the hectare (which equals 100 ares), the are still appears in land registration documents and real estate descriptions in some countries. In Japan and parts of Europe, small plots of land may be described in ares. The prefix "hect-" in hectare literally means one hundred ares.
