Prefectures in JapanAdministrative divisionone of.
Municipalities are "basic local public bodies" (Local government lawArticle 2 paragraph 4), On the other hand, prefectures are regarded as "wide-area local public bodies that include municipalities" (paragraph 5 of the same Article), and handle wide-area affairs and liaison affairs related to municipalities.

Roads are treated the same as prefectures under the Local Autonomy Law, but in addition to having a slightly different police organization from prefectures (Police lawArticles 46 and 51),River law(Article 96),Road law(Article 88), etc. have special rules about roads.
When referring to some of the prefectures in Japan, there is also a usage such as "prefecture" if Hokkaido is not included, and "prefecture" if Tokyo is not included.
Institutional change in the Meiji period

On the other hand, a private election for eachParliamentHas been installed,Local autonomyExisted.

At this point, the princes have full control over the territory and the people.EmperorAlthough it was supposed to be redeemed toBakuhan system OfEdo ShogunateMeiji government took over the status ofPrefectural Sanji systemIs called (only prefectures are under direct control).
18699/29(Meiji 28/24), the official edict ofKyoto-Tokyo-OsakaIt is decided to call all the prefectures except for the other prefectures (Kanagawa Prefecture-Niigata Prefecture-Echigofu-Kaifu-Degree-Narafu-Hakodate-Nagasaki) Changed its name to prefecture. At this point,Emperor Yukiyuki TokyoでTokyoI was there,Takagoza(Indicates the whereabouts of the EmperorThroneAnd the place where this isImperial PalaceIt is said that there is no move, so Kyoto Prefecture, which has the high Goza, has a higher ranking than Tokyo Prefecture. In addition, before this proclamation of the Prime MinisterEdo prefectureIt was renamed from Edo to Tokyo at the same time.
18718/29(Meiji 47/14) Made inAbandoned DomainAs a result, the feudal clan became a prefecture and the whole country became a direct control of the Meiji government. As a result, 1 messenger (Pioneer) 3 prefectures (Tokyo, Kyoto, Osaka) 302 prefectures. At this point, it was almost the same as the boundaries of the feudal domain and the territory of the Edo period.EnclaveWas found all over the country, hindering prefectural administration. In December of the same year, this was consolidated and merged (First prefecture integration), and became one prefecture with 1 prefectures and 3 prefectures.

Incidentally, 1903(Meiji 36), the Ministry of Interior compiled a "prefectural abolition bill" to abolish 19 prefectures and integrate them into 28 prefectures, and the Cabinet decided on it.However, due to the dissolution of the parliament due to the outbreak of the Russo-Japanese War two months after the cabinet decision, no proposal was made to the parliament.
After the abandonment of prefectures, the prefectural directors were renamed "prefectural ordinances" from "prefectural government", and the ministers of prefectures such as Kyoto, Tokyo, and Osaka were renamed "prefectural governors" to "prefectural governors." 1886After (Meiji 19), both were "GovernorWas called.

However, while the cities under “prefecture” had “mayors recommended by the city council”, the cities under “prefecture” (Tokyo city-Kyoto City-Osaka), there is no mayor, and the prefectural governor also played the role (Municipal system exceptionreference). In these three cities, 1898(Meiji 31) Only in October was the mayor born.

At that time, the jurisdiction of the Hokkaido Government was called "Hokkaido", but "Hokkaido" is simply a regional name.RegionIt is the name of the municipality, not the current "road" (InlandTransferredKarafutoInKarafuto AgencyCommon with the nomenclature). Therefore, the term "agency" was used when paralleling with other prefectures as a local government.
Under the Hokkaido government system (Meiji 19th Royal Decree No. 83 (later amended)), the Hokkaido government secretary was appointed as the governor of another prefecture. 1901(Meiji 34), (Meiji 34 Law No. 2) and (Meiji 34 Law No. 3) were promulgated and a parliament was established.CorporationIt became a local government with a personality. In addition, the authority of the parliament was narrower in the Hokkaido association than in the prefectural association.

Showa period system change
Second World WarIn 1943(18)7/1,Tokyo Metropolitan GovernmentBy the enforcement of (Law No. 18 of 89),Tokyo city TheTokyoAbsorbed byTokyo", and was stripped of the municipality and autonomy. Under the Tokyo Metropolitan Government system (Korean Decree No. 18 of 504), the "Tokyo Metropolitan Secretary" was made the secretary and Tokyo was established.Internal affairsBe a bureaucratShigeo OdateWas appointed as the first generation.
The Tokyo Metropolitan Government established a metropolitan assembly, and ward associations were also set up in each ward of the former Tokyo city, but the state's control over the ward was particularly strong.
After the war 1946(Showa 21) With the revision of the prefectural system in September, and was abolished and integrated into the prefectural system, and the law was renamed the prefectural system.According to the supplementary provisions of this revised law, the local government, which was conventionally called Hokkaido local expenses, is now called "road".
1947(22)5/3With the enforcement of the Local Autonomy Law, the government system of the Hokkaido government was abolished, and the Hokkaido government agency, which was a local government agency, became "Hokkaido" which is one of the ordinary local public bodies.
After the enforcement of Local Autonomy Law
1947(Showa 22) March,The Constitution of JapanAs the law planned in Article 92Local government lawWas promulgated. Among them, the prefectures are not in the position of the former “subordinate body of the central government”,市町村Similar toOrdinary local governmentPositioned as a member of parliamentGovernorAlsoelectionWas chosen by. However, 1947The first prefectural election for governors implemented in April (Showa 22) is not based on the local autonomy law that had not yet been enacted, but the prefectural system (prefecture system) and Tokyo Metropolitan Government system revision introduced a public election system for local ministers. It was done on the basis of that. At this time, 4 prefecture (Tokyo) 1 way (Hokkaido) 1 prefectures (Kyoto/Osaka prefecture) 2 prefectures. afterwards, 1972(Showa 47)AmericaReturned to OkinawaOkinawaHas been set up, and it has become 43 prefectures again.
While the prefectural governor is elected, it has its origins before the warAgency delegationSystem is 2000It survived for a long time until it was abolished in 12. Prefectures are usually on a par with municipalities as local public bodies, but prefectures市町村As a wide-area local public body that includes the above, the wide-area local governments, those related to communication adjustments related to municipalities, and those deemed unsuitable by ordinary municipalities due to their size or nature are processed (Local Autonomy Law (2nd Article 5))).
However, the definition of “unit” such as “capital”, “road”, “prefecture”, and “prefecture” is not specified in the Local Autonomy Law, and the current prefecture name is the same as Article 3, Paragraph 1 of the same law. It is used based on the rule that "the name of the local government is the conventional name". However, "city" is not just a name, but has a character different from "prefecture". That is, according to the Local Autonomy Law, the "ward" of the "city" is "special areaIt is said that (Local Autonomy Law Article 281 Paragraph 1), it is different from "prefecture". Even if you are a prefectureLaw on the establishment of special wards in metropolitan areasIt is possible to set up a special ward based on the above, and the prefectures that cover the special ward are, in principle, regarded as the "capital" for the application of the provisions of the Local Autonomy Law and other laws and regulations (Article 10 of the same law).
Okinawa The 1945From (20) (officiallySan Francisco Peace TreatyCame into effect 1952(27)4/28From) 1972(Showa 47)Under US occupationThen, because it was not under Japanese rule, the treatment of Okinawa at this time was delicate,国会Then "Ryukyu government","Nansei IslandsIs used, and the number of prefectures is counted as "1 prefectures" of "1 prefecture, 2 prefectures and 42 prefectures", and Okinawa is not included in the number of prefectures..
- Local council -Secretariat
Tax paid to prefectures
The merger of prefectures or the establishment of new prefectures is called "decommissioning", and can be divided as follows.
- Abolish multiple prefectures and establish new prefectures (union).
- Abolish one prefecture and make that area an area of another prefecture (transfer).
- Abolish one prefecture and set up multiple prefectures in that area (division).
- Establish a new prefecture by separating part of the prefecture area (separation).
Regarding decommissioning, “boundary change” (changing only the area without setting or abolishing prefectures)市町村Including the transfer of the prefecture to which the company belongs)Article 6 of the Local Autonomy Lawas well as the Article 6-2Stipulated in.
Principle procedure for disposal and consolidation
By law (Article 6, paragraph 1). This lawArticle 95 of the ConstitutionIt is understood that it is a "special law that applies only to one local public entity" (a special law for local autonomy) defined in stipulations. No (Detailed rulesArticle 261 of the Local Autonomy Law-Article 262).
Merge and transfer exceptions
With the revision of Law No. 16 in 57, a new procedure for merging/transferring was established by a simple method.
- When abolishing multiple prefectures and establishing new prefectures in all areas
- When one prefecture is abolished and the entire area is changed to another prefecture
- Apply by the decision of the relevant prefectural assembly,
- Determined by the Cabinet after approval by the Diet.
It was made possible to follow the procedure (Local Autonomy Law, Article 6-2).
this is,NaganoYamaguchi VillageとGifuNakatsugawaAt the time of the merger with, the fact that it was necessary to enact a law for mergers of municipalities that span prefectures (new mergers) was highlighted, andPrefectural systemIt was established with the intention of promoting voluntary merger of prefectures as the first stage of introduction.
Decommissioning and Governor/Member
- In the case of a merger, the governors of the relevant prefectures and members of the parliament will lose their jobs, and the governor's election and the member's election will be held in the newly established prefecture.
- In the case of transfer, the governor and councilor of the transferred prefecture will lose their jobs, but the governor and councilor of the transferred prefecture will not lose their jobs.
- In the case of a division, the governors and members of the prefectures to be abolished will lose their jobs, and the governors' elections and members' elections will be held in the newly established prefectures after the division.
- In the case of separation, the prefectural governors and members of the prefectural government will not lose their jobs, and the prefectural governor's election and the members' election will be held in the newly established prefecture.
Border change of prefectures is basically based on the law (Special Act on Local Autonomy) as in the case of abandonment and consolidation, but in the following cases, it will be "change itself" (Local Autonomy Act No. 6). Article 2).
- When there is a change in the boundaries of municipalities that are also boundaries of prefectures
- When municipalities were set up across the boundaries of prefectures
In these two cases, the relevant municipalities/prefectures will apply through the decisions of the respective parliament and will be determined by the Minister of Internal Affairs and Communications (Article 7 paragraph 3).
- When the area that did not belong to the area of the local government was transferred to the area of the municipality
This is because the change is due to the change in the area of the municipality, like the change of the boundary of the municipality.
Change of prefecture
Even when the whole municipality or county is transferred to another prefecture, it is a boundary change between prefectures and is subject to the law (as of September 25, 9).
Union of municipalities that span prefectures
When a municipality belonging to a different prefecture is abolished and a municipality is established in that area, the relevant municipality/prefecture applies for each through a vote of the Parliament and is determined by the Minister of Internal Affairs and Communications (Article 7, paragraph 3). ).
Conventionally, the unification of municipalities that cross the boundaries of prefectures (abolishing multiple municipalities and establishing new municipalities in that area) is also subject to the newly enacted law under Article 6 Clause 1. It was supposed to be (No. 28 of own departure from June 6, 29).
For that reason, 2005(Heisei(17) The merger of Yamaguchi Village in Nagano Prefecture and Nakatsugawa City in Gifu Prefecture will take the form of transfer to Nakatsugawa City. Taking this as an opportunity, it was decided that the amendment under Law No. 16 in 57 would be similar to the procedure for changing the boundaries of municipalities across prefecture boundaries.
Area where division theory exists
1876In some prefectures where a large-scale merger was carried out (Meiji 9), there are some prefectures that were divided again due to the division movement. 1888(Meiji 21) At the endKagawa EhimeNo division of prefectures has been implemented since it was separated from.
However, even now, there are voices calling for the division of prefectures, such as the mayors, prefectural governors, and online. Here, we list the prefectures where the mayor or prefectural governor suggests division or separation of prefectures.

As is clear from the table (location and county of government office when the prefecture was established), the principle of prefecture name is the location of the government office. However, if the place name on which the prefecture name is based falls under the following, the prefecture name does not match the current city name of the residence.
- When it is "county name" instead of "city name" of the location of the government building (prefectures in which the "country county" column is colored blue in the table, except for the two prefectures whose city names have been changed later).
- If it is not the current location of the government building (Tochigi-Gunma-Saitama-Mie）.
- If it does not exist as a "city" due to a city merger (Tokyo-Kanagawa-Hyogo).
- If neither "city name" nor "county name" (Hokkaido-Ehime-Okinawa）.
