Tōbui
Tōbui lies in southern Tokachi, where the Tōbui River runs toward the Pacific through a country of rivers and woods. Its name comes from the Ainu words for a lake and an opening, originally applied to the river near its mouth. Across Tokachi, Ainu communities made their homes along waterways, fishing for salmon and hunting deer; the products of river and forest also entered their trade with the Matsumae domain.
