Special wards of Tokyo

Special wards (特別区, tokubetsu-ku) are a special form of municipalities in Japan under the 1947 Local Autonomy Law. They are city-level wards: primary subdivisions of a prefecture with municipal autonomy largely comparable to other forms of municipalities.

Although the autonomy law today allows for special wards to be established in other prefectures, to date they exist only in Tokyo, which consists of 23 special wards and 39 other, ordinary municipalities (cities, towns, and villages).[1] The special wards of Tokyo occupy the land that was Tokyo City in its 1936 borders before it was abolished under the Tōjō Cabinet in 1943 to become directly ruled by the prefectural government, then renamed to "Metropolitan". During the Occupation of Japan, municipal autonomy was restored to former Tokyo City by the establishment of special wards, each with directly elected mayor and assembly, as in any other city, town or village in Tokyo and the rest of the country.


In Japanese, they are collectively also known as "Wards area of Tokyo Metropolis" (東京都区部, Tōkyō-to kubu), "former Tokyo City" (旧東京市, kyū-Tōkyō-shi), or less formally the 23 wards (23区, nijūsan-ku) or just Tokyo (東京, Tōkyō) if the context makes obvious that this does not refer to the whole prefecture. Today, all wards refer to themselves as a city in English, but the Japanese designation of special ward (tokubetsu-ku) remains unchanged. They are a group of 23 municipalities; there is no associated single government body separate from the Tokyo Metropolitan Government, which governs all 62 municipalities of Tokyo, not just the special wards.

Analogues in other countries[edit]

Analogues exist in historic and contemporary Chinese and Korean administration: "Special wards" are city-independent wards, analogously, "special cities/special cities" (teukbyeol-si/tokubetsu-shi) are province-/prefecture-independent cities and were intended to be introduced under SCAP in Japan, too; but in Japan, implementation was stalled, and in 1956 special cities were replaced in the Local Autonomy Law with designated major cities which gain additional autonomy, but remain part of prefectures. In everyday English, Tokyo as a whole is also referred to as a city even though it contains 62 cities, towns, villages and special wards. The closest English equivalents for the special wards would be the London boroughs or New York City boroughs if Greater London and New York City had been abolished in the same way as Tokyo City, making the boroughs top-level divisions of England or New York state.

Differences from other municipalities[edit]

Although special wards are autonomous from the Tokyo metropolitan government, they also function as a single urban entity in respect to certain public services, including water supply, sewage disposal, and fire services. These services are handled by the Tokyo metropolitan government, whereas cities would normally provide these services themselves. This situation is identical between the Federal District and its 35 administrative regions in Brazil. To finance the joint public services it provides to the 23 wards, the metropolitan government levies some of the taxes that would normally be levied by city governments, and also makes transfer payments to wards that cannot finance their own local administration.[2]


Waste disposal is handled by each ward under direction of the metropolitan government. For example, plastics were generally handled as non-burnable waste until the metropolitan government announced a plan to halt burying of plastic waste by 2010; as a result, about half of the special wards now treat plastics as burnable waste, while the other half mandate recycling of either all or some plastics.[3]


Unlike other municipalities (including the municipalities of western Tokyo), special wards were initially not considered to be local public entities for purposes of the Constitution of Japan. This means that they had no constitutional right to pass their own legislation, or to hold direct elections for mayors and councilors. While these authorities were granted by statute during the US-led occupation and again in 1975, they could be unilaterally revoked by the National Diet; similar measures against other municipalities would require a constitutional amendment. The denial of elected mayors to the special wards was reaffirmed by the Supreme Court in the 1963 decision Japan v. Kobayashi et al. (also known as Tokyo Ward Autonomy Case).


In 1998, the National Diet passed a revision of the Local Autonomy Law (effective in the year 2000) that implemented the conclusions of the Final Report on the Tokyo Ward System Reform increasing their fiscal autonomy and established the wards as basic local public entities.
