5. Local Government
While the national government is in charge of defense, foreign policy, and other functions that are the inherent responsibility of the state, local governments—both prefectural and municipal—are in charge of matters related to land regulation and development, disaster prevention and pollution control, labor, education, social welfare and health. Prefectural gov-ernments are entrusted with affairs that are large in scale or affect a relatively wide area and often act as a liaison in coordinating the activities of two or more municipal bodies. Municipal governments, for their part, are charged with responsibility for the administration of matters that are closely related to the daily life of their respective communities.
As of February 2004 there were 47 prefectures and 3,170 municipalities (including 13 ordinance-designated cities, which in principal have more than one million inhabitants) in Japan.(*1) Due to the aging of society and diversification of values, administrative needs are increasing. To deal with this situation, the central government is urging local governments to strengthen their administrative and fiscal base by merging with other local governments. The home affairs ministry aims to reduce the number of municipalities to less than 2,000 before a special law designed to promote municipal mergers expires at the end of March 2005. According to the ministry, 1,893 municipalities have made use of the special law to set up a total of 505 councils as of January 2004 to discuss mergers with potential partners.(*2)

"Trinity Reform"
In June 2003 Prime Minister Junichiro Koizumi decided to cut subsidies to local authorities by ¥4 trillion and transfer greater taxing authority from the national to local governments over three years starting from the fiscal year 2004.(*3) The steps are part of the so-called "trinity reform" aimed at reducing the reliance of regional governments on subsidies and local tax grants allocated to local authorities by the central government, by apportioning a wider range of authority over national taxes to local governments. The reform is called "trinity" because it focuses on three systems—subsidies, tax allocation and the transfer of taxing authority.
