Tokachi River Trout

Tokachi River is a river in Hokkaidō, Japan. In 1820, the explorer Takeshiro Matsuura 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".
