The , passed by the House of Representatives and the House of Peers on March 28, 1947 and promulgated as Law No. 67 of 1947 on April 17, is an Act of devolution that established most of Japan's contemporary local government structures and administrative divisions, including prefectures, municipalities and other entities. On July 16, 1999, the law was amended to eliminate administrative functions imposed upon local governments by the central governments and to establish Committee for Settling National-Local Disputes. The law and other relevant laws have been amended after the revision to promote decentralization. Local public entities The classification of (LPEs) are: Ordinary LPEs Prefectures (to, dō, fu and ken) Municipalities Cities Towns Villages Special LPEs (incomplete) Special wards of Tokyo Unions of LPEs Partial operating unions Full operating unions Office operating unions Regional unions Property districts Regional development enterprises Ordinary LPEs are the basic local governments.

The Ministry generally approves all inter-prefectural special LPEs, while inter-municipal special LPEs are approved by prefectural governors. Revision The Local Autonomy Act (paragraph 5 of Article 2) was revised in 1969 that required local governments to produce a forward-looking Basic Plan (kihon keikaku) for their long-term economic and social development, to cover a duration of around 25 years. It has to be approved by the elected local council as part of a comprehensive planning that tied to the local fiscal decision. Takegawa notes that in 1970, less than 10% of local governments had made comprehensive plans, by 1975 the number had gone up to 75%, and in 1980 it was almost 90%. In January 2011, the Ministry of Internal Affairs and Communications announced plans to revise the law to enable the national
