Japan's local government system has evolved since the Meiji Restoration, with significant changes after World War II. The current two-tiered structure consists of 47 prefectures and 1,718 municipalities, each with elected assemblies and executives. Local governments manage various services, from education to public works. They face challenges like depopulation and fiscal constraints, leading to reforms such as municipal mergers and decentralization efforts. The relationship with the central government remains complex, balancing autonomy and oversight.
