Local Government Under the Constitution of Japan

Introduction

Chapter VIII (Articles 92–95) establishes local self-government (chihō jichi), reflecting the Occupation-era commitment to decentralization as a check against centralized authoritarianism. The Meiji Constitution contained no provisions on local government, and the prewar system was characterized by strong central control.

Constitutional Framework

Article 92 requires that regulations concerning local public entities be “fixed by law in accordance with the principle of local autonomy.” Article 93 mandates directly elected assemblies and chief executives, ensuring democratic legitimacy. Article 94 empowers local entities to “manage their property, affairs and administration and to enact their own regulations within the law.” Article 95 provides that a law applicable only to a single local entity may not be enacted without the consent of a majority of its residents, preventing discriminatory treatment by the national government.

The Local Autonomy Act

The Local Autonomy Act (Chihō Jichi Hō) of 1947, with over 300 articles, is the primary implementing legislation. It defines the types of local entities, their organizational structures, powers, and relationships with the central government.

Structure

Japan has a two-tier system: 47 prefectures (todōfuken — prefectures, urban prefectures, the Tokyo Metropolis, and Hokkaido) and municipalities (shichōson — cities, towns, villages). The 23 special wards of Tokyo constitute a unique category of local government exercising municipal-level functions within the Tokyo Metropolis. Each entity has a directly elected legislative assembly and chief executive (governor at prefectural level, mayor at municipal level), ensuring democratic accountability to local electorates.

Powers of Local Governments

Local governments exercise autonomous functions — enacting local by-laws (jōrei), levying local taxes (within limits set by the Local Tax Act), managing local property and public enterprises, and delivering public services including education, welfare, public health, and infrastructure. They also exercise statutory delegated functions (hōtei itaku jimu), introduced in the 1999 decentralization reform to replace the former system of agency-delegated functions (kikan itaku jimu) under which local governments had performed functions on behalf of the central government subject to central direction.

Central-Local Relations

The central government exercises control through legislative control (national legislation sets uniform standards; local by-laws must not conflict), fiscal control (the central government collects approximately 60% of tax revenue but is responsible for only about 40% of expenditure; the gap is filled through the Local Allocation Tax system which redistributes national revenues to local governments based on fiscal need), and administrative supervision by the Ministry of Internal Affairs and Communications.

The Decentralization Reforms

The Heisei decentralization reforms (1999–2006) abolished the system of agency-delegated functions, replacing it with the statutory delegated function system that gives local governments greater discretion. The Trinity Reform (2004–2006) reduced central subsidies by approximately 4 trillion yen while increasing the Local Allocation Tax and transferring tax sources to local governments, aiming to increase fiscal autonomy.

The Heisei Municipal Mergers

The Great Heisei Municipal Mergers (1999–2010) reduced municipalities from 3,232 to 1,719 through central government financial incentives, aiming to create entities with sufficient administrative capacity. The mergers have been criticized for reducing local representation and weakening community identity.

Local Government and Constitutional Rights

Local governments administer public education, social welfare, public health, and environmental protection, and regulate land use and commerce within their jurisdictions. Their actions are subject to constitutional constraints, and local by-laws may be challenged in court for violating fundamental rights, providing a mechanism for local accountability.

Conclusion

The constitutional framework for local self-government has moved from strong central control toward greater local autonomy over the decades, though the central government retains substantial fiscal and supervisory powers. The appropriate balance between national uniformity and local diversity remains an ongoing debate.
