{{Administrative divisions of Japan}}

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, preferred by the English Wikipedia, groups the prefectures into eight regions. In that division, 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.{{Cite web |url=http://www.travelwithamnet.com/regions |title=Regions |access-date=2021-02-14 |archive-date=2020-07-27 |archive-url=https://web.archive.org/web/20200727150921/http://www.travelwithamnet.com/regions |url-status=dead }}[https://www.japan-guide.com/list/e1001.html Regions of Japan][https://www.jrpass.com/blog/a-guide-to-the-regions-of-japan A Guide to the Regions of Japan]

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

This is a list of Japan's major islands, traditional regions, and subregions, going from northeast to southwest.[http://www.japan-guide.com/list/e1001.html Regions of Japan on japan-guide.com][http://web-japan.org/kidsweb/explore/regions/ Regions of Japan on web-japan.org] The eight traditional regions are marked in bold.

Other regional divisions

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:

Regions as administrative units

In the later stages of World War II, in preparation for an Allied invation 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:

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.
