Prefectures of Japan

Prefectures of Japan (都道府県, todōfuken) are one of the basic local entities of Japan.^[1] They are the 47 subdivisions of the country. Prefectures are the governmental bodies of Japan which are larger than cities, towns, and villages.

History

The former provinces of Japan were converted into prefectures between 1876 and 1879.^[2]

The word todōfuken combines the suffixes of the names of the 47 prefectures.^[1] The four suffixes are:

• -to .... one metropolis, or large city (都 -to), Tokyo (東京都, Tōkyōto)

• -dō .... one “circuit” (道 -dō), Hokkaido (北海道, Hokkaidō)
• -fu .... two city prefectures (府 -fu), Osaka (大阪府, Ōsakafu) and Kyoto (京都府, Kyōtofu)
• -ken ... forty-three other prefectures (県 -ken)

Before World War II, different laws applied to fu and ken, but now two types of prefecture are the same, outside of their names.

Lists of prefectures

List in Japanese ISO order

The prefectures are often grouped into these nine regions (Chihō). The regions are not formally specified, they do not have elected officials, and they are not corporate bodies. However, the practice of ordering prefectures based on their geographic region is traditional.^[2] This ordering is mirrored in Japan's International Organization for Standardization (ISO) coding.^[3] From north to south, the prefectures of Japan and their commonly associated regions are listed in traditional and in ISO 3166-2:JP order:

Hokkaidō 1. Hokkaidō Tōhoku 2. Aomori 3. Iwate 4. Miyagi 5. Akita 6. Yamagata 7. Fukushima Kantō 8. Ibaraki 9. Tochigi 10. Gunma 11. Saitama 12. Chiba 13. Tokyo[4] 14. Kanagawa

Chūbu 15. Niigata 16. Toyama 17. Ishikawa 18. Fukui 19. Yamanashi 20. Nagano 21. Gifu 22. Shizuoka 23. Aichi Kansai 24. Mie 25. Shiga 26. Kyoto 27. Osaka 28. Hyōgo 29. Nara 30. Wakayama Chūgoku 31. Tottori 32. Shimane 33. Okayama 34. Hiroshima 35. Yamaguchi

Okinawa Prefecture is traditionally thought of as part of the Kyūshū region of Japan.^[5] Okinawa Prefecture is made up of islands which are southwest of the island of Kyushu.^[6] The Japanese government recognizes the prefecture as its own region in new 9-region, 11-region and 13-region systems.^[7]
