Tokachi River
| Tokachi River (十勝川, Tokachi-gawa) is a river in Hokkaidō, Japan. In 1820, the explorer Takeshiro Matsuura (松浦 武四郎) proposed "Tokachi" as the name of the surrounding Tokachi Province, with each character corresponding to a Japanese homophone. The province was named after this river, which in turn was derived from the Ainu language word "tokapci" (トカㇷ゚チ). | ||||||
