Chubu has three major subregions: Tokai region in coastal area of the Pacific Ocean, Hokuriku region in that of the Sea of Japan, and Koshin'etsu region for the rest.
Hokuriku, the Central Highlands, and Tokai, although grouped together as the Chubu District, are vastly diverse in climate, geography, historical background, and folkways.
Chubu is endless mountains and fathomless gorges, especially in the Central Highlands.
Chubu's climate varies considerably due to the fact that this enormous district stretches from the Japan Sea to the Pacific, with weather-buffeting mountains in between.
Chubu means "middle region", accurately reflecting its position straddling the two Japanese poles of Kansai and Kanto.
Chubu Centrair International Airport, Japan's third major international gateway, is located on an artificial island 30 minutes south from Nagoya.
Chubu is sake country and Niigata, renowned for its koshihikari rice, produces some of the best in the country including famous labels like Kubota (久保田), Koshinokanbai (越乃寒梅) and Hakkaisan (八海山).
