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.
この地域では一反歩あたりの収穫量が記録されている。
In this region, the yield per tanbu is recorded.
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.
