Subprefectures of Hokkaido

Hokkaido Prefecture had 14 branch offices called 支庁 (shichō) in Japanese, which is often translated in English as subprefectures. Normally, a subprefecture consists of a few to a dozen cities, towns, and/or villages. From April 2010, Hokkaido has 9 General Subprefectural Bureaus (総合振興局, sōgō-shinkō-kyoku, literally "Comprehensive Promotion Bureau") and 5 Subprefectural Bureaus (振興局, shinkō-kyoku, literally "Promotion Bureau")).

For historical reasons, some older people in Hokkaido use the subprefecture name suffixed by -kannai in their address.

History

1897	Nineteen shichō were placed under Hokkaido Agency (an agency of the national government): Sapporo, Hakodate, Kameda, Matsumae, Hiyama, Suttsu, Iwanai, Otaru, Sorachi, Kamikawa, Mashike, Souya, Abashiri, Muroran, Urakawa, Kushiro, Kasai, Nemuro, and Shana.

Reorganization

The prefectural government of Hokkaido planned to reorganize the current 14 subprefectures into 9 subprefectural bureaus. Five subprefectures, namely Hidaka, Hiyama, Ishikari, Nemuro, and Rumoi were subject to be cut down. The capital municipalities of these subprefectures opposed the plan, but on June 28, 2008, the prefectural council passed the ordinance of the reorganization. The change should have taken effect in April 2009.

However, it was impossible to make the reform on time. The Public Offices Election Act and the Election Law were not amended on April 1, 2009, but the amendment the Public Offices Election Act was passed in the prefectural assembly on March 31, 2009 and took effect from April 1, 2010.
