Tokachi Plain (Japanese: 十勝平野) is a plain facing the Pacific Ocean, located in the southeastern part of Hokkaido. The area of the plain is approximately 3600km2.
Matsuura Takeshirō invented the name "Tokachi" based on the Ainu word tokapci (トカㇷ゚チ), meaning a breast, possibly referring to a breast-shaped hill.
