List of regions of Japan

Japan is divided into eight regions. They are not official administrative units, though they have been used by government officials for statistical and other purposes since 1905. They are widely used in, for example, maps, geography textbooks, and weather reports, and many businesses and institutions use their home regions in their names as well, for example Kyushu National Museum, Kinki Nippon Railway, Chūgoku Bank, and Tōhoku University.

Map of the regions of Japan. From northeast to southwest: Hokkaidō (red), Tōhoku (yellow), Kantō (green), Chūbu (cyan), Kansai (indigo), Chūgoku (orange), Shikoku (purple), and Kyūshū & Okinawa (grey).

Each region contains one or more of the country's 47 prefectures. Of the four main islands of Japan, Hokkaidō, Shikoku, and Kyūshū make up one region each, the latter also containing the Satsunan Islands, while the largest island Honshū is divided into five regions. Okinawa Prefecture is usually included in Kyūshū, but is sometimes treated as its own ninth region.^[1][2][3]

Japan has eight High Courts, but their jurisdictions do not correspond to the eight regions (see Judicial system of Japan for details).

Other regional divisions

Examples of regional divisions of Japan as used by various institutions are:
