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.
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).
| Region | Population | Area in km2[4] | Prefectures contained |
|---|---|---|---|
| Hokkaidō | 5.4 million[5] | 83,000 | Hokkaidō |
| Tōhoku | 8.9 million[6] | 67,000 | Akita, Aomori, Fukushima, Iwate, Miyagi, Yamagata |
| Kantō | 43.3 million[7] | 32,000 | Chiba, Gunma, Ibaraki, Kanagawa, Saitama, Tochigi, Tōkyō |
| Chūbu | 21.4 million[8] | 67,000 | Aichi, Fukui, Gifu, Ishikawa, Nagano, Niigata, Shizuoka, Toyama, Yamanashi |
| Kansai (also known as Kinki) | 22.5 million[9] | 33,000 | Hyōgo, Kyōto, Mie, Nara, Ōsaka, Shiga, Wakayama |
| Chūgoku | 7.3 million[10] | 32,000 | Hiroshima, Okayama, Shimane, Tottori, Yamaguchi |
| Shikoku | 3.8 million[11] | 19,000 | Ehime, Kagawa, Kōchi, Tokushima |
| Kyūshū & Okinawa | 14.3 million[12] | 44,000 | Fukuoka, Kagoshima, Kumamoto, Miyazaki, Nagasaki, Ōita, Okinawa, Saga |
This is a list of Japan's major islands, traditional regions, and subregions, going from northeast to southwest.[13][14] The eight traditional regions are marked in bold.
In many contexts in Japan (government, media markets, sports, regional business or trade union confederations), regions are used that deviate from the above-mentioned common geographical 8-region division that is sometimes referred to as "the" regions of Japan in the English Wikipedia and some other English-language publications. Examples of regional divisions of Japan as used by various institutions are:
