List of regions of Japan
From Wikipedia, the free encyclopedia
Japan is often divided into regions, each containing one or more of the country's 47 prefectures at large. Sometimes, they are referred to as "blocs" (ブロック, burokku), or "regional blocs" (地域ブロック, chiiki burokku) as opposed to more granular regional divisions. 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.
One common division groups the prefectures into eight regions. In this arrangement, three of the four main islands of Japan, namely Hokkaidō, Shikoku, and Kyūshū, each form their own region, while the largest island, Honshū, is split into five regions. Minor islands are grouped with the larger ones, for example with the Satsunan Islands being included under Kyūshū and the Tokyo Islands under Kantō. Okinawa Prefecture is usually considered part of Kyūshū, but is sometimes treated as its own ninth region.
Japan has eight High Courts, but their jurisdictions do not match the typical eight-region geographical division (see #Other regional divisions and Judicial system of Japan for details).

Other regional divisions
In many contexts in Japan (government, media markets, sports, regional business or trade union confederations), regional groupings are used that digress from the above-mentioned common 8-region geographical division. The 8-region model is frequently regarded as a standard on the English Wikipedia and some other English-language publications. Examples of regional divisions used by other particular institutions include:

Regions as administrative units
In the later stages of World War II, in preparation for an Allied invasion of the home islands, regions served as administrative units between the Home Ministry and the governments of prefectures from 1943. Initially, nine "regional administrative joint conferences" (地方行政協議会, chihō gyōsei kyō-kaigi) were set up, each comprising several prefectural governments under the leadership of one prefectural government. In 1945, they were consolidated into eight centralized "regional governorates-general" (地方総監府, chihō sōkan-fu) with authority of command over the subordinate prefectural governments. The regions corresponded territorially to the military districts (軍管区, gunkan-ku) as used by the Imperial Army in 1945. They were namely:
| Region (-chihō) | Prefectures (-to/-chō/-fu/-ken) | Seat of the governorate-general | Regional governor-general (chihō sōkan) (initially in June 1945) | Corresponding Imperial Army military district (gunkan-ku) |
|---|---|---|---|---|
| Hokkai | Karafuto, Hokkaidō | Sapporo City | Kumagai Ken'ichi (concurrent governor of Hokkaidō(-chō)) | Hokubu (Northern) |
| Tōhoku | Aomori, Iwate, Miyagi, Akita, Yamagata, Fukushima | Sendai City | Maruyama Tsurukichi (previous governor of Miyagi) | Tōhoku (Northeastern) |
| Kantō-Shin'etsu | Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Yamanashi, Niigata, Nagano | Tokyo | Nishio Toshizō (concurrent governor of Tokyo) | Tōbu (Eastern) |
| Tōkai-Hokuriku | Gifu, Shizuoka, Aichi, Mie, Toyama, Ishikawa | Nagoya City | Obata Tadayoshi (previous governor of Aichi) | Tōkai |
| Kinki | Shiga, Kyoto, Osaka, Hyōgo, Nara, Wakayama, Fukui | Osaka City | Yasui Eiji (previous governor of Osaka) | Chūbu (Central) |
| Chūgoku | Tottori, Shimane, Okayama, Hiroshima, Yamaguchi | Hiroshima City | Ōtsuka Isei (previous governor of Hiroshima) | Chūgoku |
| Shikoku | Tokushima, Kagawa, Ehime, Kōchi | Takamatsu City | Kimura Masayoshi (concurrent governor of Kagawa) | Shikoku |
| Kyūshū | Fukuoka, Saga, Nagasaki, Kumamoto, Ōita, Miyazaki, Kagoshima, Okinawa | Fukuoka City | Totsuka Kuichirō (previous governor of Fukuoka) | Seibu (Western) |
After capitulation, the governorates-general were immediately dissolved by GHQ/SCAP and the (in the Empire: very limited) local autonomy of prefectural governments and their elected assemblies restored to be eventually substantially expanded by the Constitution and the Local Autonomy Law in 1947.
