unit of land area (approx. one-tenth hectare)
Historical Japanese unit of land area, roughly 991.7 m². Used in agricultural and land records, now largely replaced by metric units.
In the past, the size of farmland was expressed in tanbu.
In this region, the yield per tanbu is recorded.
Modern metric unit; 1 hectare = about 10.08 反歩.
Standard kanji spelling for this historical land-area unit.
Alternate kanji spelling; less common than 反歩.
Compound of 反 (tan, a traditional land-area unit) and 歩 (bu, a unit of length/area). The exact historical derivation is uncertain, but the term has been used in Japanese land measurement for centuries.
