Chūgoku中国

Chūgoku. A region (地方, chihō) of Japan.

Western Honshū, divided by mountains into the San'yō coast on the Inland Sea and the San'in coast on the Sea of Japan.

A region has no assembly, no governor, and no budget. It is a grouping used in weather forecasts, school textbooks, and business planning, and its borders are a convention, not a law. Each prefecture in it is a government.
