A prefecture is an administrative jurisdiction traditionally governed by an appointed prefect. This can be a regional or local government subdivision in various countries, or a subdivision in certain international church structures, as well as in antiquity a Roman district.
Japan is divided into 47 prefectures, which rank immediately below the national government and form the country's first level of jurisdiction and administrative division. They include 43 prefectures proper, two urban prefectures, one regional prefecture and one metropolis. In 1868, the Meiji Fuhanken sanchisei administration created the first prefectures to replace the urban and rural administrators in the parts of the country previously controlled directly by the shogunate and a few territories of rebels/shogunate loyalists who had not submitted to the new government such as Aizu/Wakamatsu. In 1871, all remaining feudal domains (han) were also transformed into prefectures, so that prefectures subdivided the whole country. In several waves of territorial consolidation, today's 47 prefectures were formed by the turn of the century. In many instances, these are contiguous with the ancient ritsuryō provinces of Japan.
A city is a local administrative unit in Japan. Cities are ranked on the same level as towns and villages, with the difference that they are not a component of districts. Like other contemporary administrative units, they are defined by the Local Autonomy Law of 1947.
In Japan, a district is composed of one or more rural municipalities within a prefecture. Districts have no governing function, and are only used for geographic or statistical purposes such as mailing addresses. Cities are not part of districts.
Special wards 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.
A city designated by government ordinance, also known as a designated city or government ordinance city, is a Japanese city that has a population greater than 500,000 and has been designated as such by order of the Cabinet of Japan under Article 252, Section 19, of the Local Autonomy Law.
The Japanese addressing system is used to identify a specific location in Japan. When written in Japanese characters, addresses start with the largest geographical entity and proceed to the most specific one. The Japanese system is complex and idiosyncratic, the product of the natural growth of urban areas, as opposed to the systems used in cities that are laid out as grids and divided into quadrants or districts.
Japan has three levels of governments: national, prefectural, and municipal. The nation is divided into 47 prefectures. Each prefecture consists of numerous municipalities, with 1,719 in total. There are four types of municipalities in Japan: cities, towns, villages and special wards. In Japanese, this system is known as shikuchōson (市区町村), where each kanji in the word represents one of the four types of municipalities. Some designated cities also have further administrative subdivisions, also known as wards. But, unlike the Special wards of Tokyo, these wards are not municipalities.
Tokyo City was a municipality in Japan and part of Tokyo-fu which existed from 1 May 1889 until its merger with its prefecture on 1 July 1943. The historical boundaries of Tokyo City are now occupied by the special wards of Tokyo. The newly-merged government became what is now Tokyo, also known as the Tokyo Metropolis or, ambiguously, Tokyo Prefecture.
Tokyo Prefecture was a Japanese government entity that existed between 1868 and 1943.
Subprefecture of Japan are a Japanese form of self-government which focuses on local issues below the prefectural level. It acts as part of the greater administration of the state and as part of a self-government system.
Shiga was a district located in Shiga Prefecture, Japan.
Japanese place names include names for geographic features, present and former administrative divisions, transportation facilities such as railroad stations, and historic sites in Japan. The article Japanese addressing system contains related information on postal addresses.
Western Tokyo, also known as the Tama area, Tama region or toka (都下), in the Tokyo Metropolis consists of 30 ordinary municipalities, unlike the eastern part which consists of 23 special wards.
The Tokyo Metropolitan Government is the government of the Tokyo Metropolis. One of the 47 prefectures of Japan, the government consists of a popularly elected governor and assembly. The headquarters building is located in the ward of Shinjuku. The metropolitan government administers the special wards, cities, towns and villages that constitute part of the Tokyo Metropolis. With a population closing in on 14 million living within its boundaries, and many more commuting from neighbouring prefectures, the metropolitan government wields significant political power within Japan.
Politics of Osaka City, as in all municipalities of Japan, takes place in the framework of local autonomy that is guaranteed by chapter 8 of the Constitution and laid out in the Local Autonomy Law. As one of Japan's 20 major cities designated by government ordinance, Osaka City has some administrative responsibilities that are handled by the prefectures in ordinary municipalities and is subdivided into wards.
Fu is a traditional administrative division of Chinese origin used in the East Asian cultural sphere, translated variously as commandery, prefecture, urban prefecture, or city. They were first instituted as a regular form of administrative division of China's Tang Empire, but were later adopted in Vietnam, Japan and Korea. At present, only two fu still remain: the prefectures of Kyoto and Osaka in Japan.
