Tokachi River (十勝川, Tokachi-gawa) is a river in Hokkaidō, Japan.

Etymology

[edit]

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).

Although the exact origins of "tokapci" were unknown, Hidezo Yamada, an Ainu language researcher, proposed these origins:

tokap-usi ("breast, somewhere")
toka-o-pci ("swamp, around a place, either")
