About Tatami/Sqm Converter
The Tatami/Sqm Converter is an online tool for converting between tatami (jo), square meters (m²), and tsubo — area units commonly used in Japan for measuring room sizes and property areas.
Since tatami mat sizes vary significantly by region in Japan, this tool supports four regional standards: Kyoma (Kansai region, ~1.82 m²/tatami), Chukyoma (Tokai region, ~1.6562 m²/tatami), Edoma (Kanto region, ~1.548 m²/tatami), and Danchima (public housing, ~1.445 m²/tatami). By selecting the appropriate tatami type, you can perform precise area conversions tailored to your specific region.
Essential for apartment hunting, moving plans, and renovation projects in Japan. Instantly convert property listings and room measurements between tatami, square meters, and tsubo units.
