About the Japan Tsubo & Jo Converter
Renting an apartment or buying property in Japan can be confusing due to traditional measurement units like Tsubo and Jo. The Japan Tsubo & Jo to Square Meters Converter helps expats, real estate agents, and investors instantly translate Japanese real estate listings into understandable Square Meters and Square Feet.
"Jo" (畳) is traditionally used to describe the size of a single room based on the number of Tatami mats that can fit in it. "Tsubo" (坪) is the official metric used by brokers to measure the overall land plot or total floor space of a house. Use our free calculator to accurately compare property sizes in Tokyo, Osaka, or Hokkaido with Western metrics without doing manual arithmetic.
Frequently Asked Questions
What is a Tsubo?
A Tsubo (坪) is a traditional Japanese unit of area roughly equal to the size of two standard Tatami mats. Officially, 1 Tsubo is exactly equal to 3.305785 square meters (or about 35.58 square feet).
What does Jo (畳) mean in apartment listings?
Jo refers to the size of a single Tatami mat, and is used to describe the floor area of a bedroom or living room (e.g., a "6 Jo room"). While Tatami sizes vary slightly by region (Kyoto vs. Tokyo), the real estate standard calculates 1 Jo as exactly 1.62 square meters.
How many Jo are in a Tsubo?
Because a Tsubo is fundamentally defined as two Tatami mats placed side-by-side, 1 Tsubo is equivalent to 2 Jo.
