Prefectures of Japan

Japan is organized into 47 distinct administrative regions known as prefectures.

These prefectures serve as the first level of jurisdiction below the national government. They act as the primary way the country is divided for local management. While they are all parts of the same nation, they function with specific local duties. This system allows the central government to delegate important tasks across the entire Japanese archipelago.

The prefectural system is divided into four specific types. Most of these are called ken, which means prefecture. There are also two urban prefectures known as fu: Osaka and Kyoto. One large regional prefecture is called a dō, which refers to Hokkaidō. Finally, the capital is a special metropolis called a to, known as Tokyo.

Despite these different names, there is very little functional difference in how these four types of local governments operate.

Each prefecture manages several essential public services. They are responsible for organizing the prefectural police force. They also supervise schools and maintain prefectural hospitals. Other duties include the maintenance of prefectural roads and the supervision of waterways. They even assist with regional urban planning. To lead these areas, citizens directly elect a chief executive. They also elect a unicameral assembly, which is a single-chamber legislative body. This assembly meets to enact ordinances and decide on local budgets.

The history of these borders is quite complex. In the 16th century, Portuguese traders used the word "prefeitura" to describe local fiefdoms. This term eventually became the Western word for prefecture. During the Edo period, the Tokugawa shogunate ruled over about 302 different areas. In 1868, the Meiji government began replacing old administrators with the first prefectures. This started with the Meiji Fuhanken sanchisei administration. Initially, there were over 300 prefectures. This number dropped to 72 in late 1871. By 1888, the number reached the 47 prefectures used today.

Tokyo has a very unique administrative history. In 1943, during World War II, Tokyo became a to, or metropolis. This was done to consolidate administration around the capital. The government wanted more control during the war. After the war, the Potsdam Declaration led to decentralization. In 1947, the city was reorganized into 23 special wards.

These wards were meant to be equal to other municipalities. It took until the year 2000 for these special wards to be fully recognized as municipal-level entities.

Power is shared between the local and national levels in a unitary state. This means the central government holds the ultimate authority. The central government delegates many functions to the prefectures. However, it also controls local budgets, tax rates, and borrowing. Local government expenditure accounts for 70 percent of overall government spending. Even so, many municipalities depend heavily on national funding. This dependency is often higher in rural areas where populations are declining.

In 2003, there was a proposal to change the system significantly. Prime Minister Junichiro Koizumi suggested a plan called dōshūsei. This plan aimed to consolidate the 47 prefectures into about 10 regional states. These states would have much greater autonomy than current prefectures. The goal was to reduce administrative costs and simplify subprefecture regions. However, the Japanese government abandoned this plan as of August 2012.

Every prefecture maintains its own unique identity through a mon. A mon is a special symbol equivalent to a coat of arms in the West. It serves as a way for each region to be identified. While the central government sets the basic framework for many laws, the prefectures remain vital. They coordinate with municipalities to ensure services reach every part of the country. Through this system, Japan balances national unity with local management.
