Cho
The chō is a traditional Japanese unit of land area, historically used for measuring large agricultural fields and forests. Symbolized as chō, one chō equals 3,000 tsubo, or approximately 9,917.36 square metres (nearly one hectare). Standardized under the Weights and Measures Law of 1891 within the shaku-kan system, the chō was widely used across Japan until the metric system became compulsory for official transactions in 1959.
