[[Japan]] is divided into 47 [[prefecture]]s ({{nihongo2|都道府県}}, {{lang|ja-latn|todōfuken}}, {{IPA|ja|todoːɸɯ̥ꜜkeɴ||TomJ-Prefectures.ogg}}), which rank immediately below the national government and form the country's first level of [[jurisdiction]] and [[Administrative divisions of Japan|administrative division]]. They include 43  prefectures proper ({{nihongo2 |県}}, ''[[#Ken|ken]]''), two [[Fu (administrative division)|urban prefectures]] ({{nihongo2 |府}}, ''[[#Fu|fu]]'': [[Osaka Prefecture|Osaka]] and [[Kyoto Prefecture|Kyoto]]), one regional prefecture ({{nihongo2 |道}}, ''[[#Dō|dō]]'': [[Hokkaido|Hokkaidō]]) and one metropolis ({{nihongo2 |都}}, ''[[#To|to]]'': [[Tokyo]]). <!--The following already implicit?: Prefectures are {{clarify span|governmental bodies}} larger than [[Cities of Japan|cities]], [[Towns of Japan|towns]], and [[Villages of Japan|villages]].-->
In 1868, the [[Meiji Restoration|Meiji]] ''[[Fuhanken sanchisei]]'' administration created the first prefectures (urban ''fu'' and rural ''ken'') to replace the urban and rural administrators (''[[bugyō]]'', ''[[daikan]]'', etc.) in the [[Tenryō|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 domain|Aizu]]/[[Aizuwakamatsu|Wakamatsu]]. In 1871, all remaining feudal domains ''([[Han system|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]].<ref name="nussbaum780">[[Louis-Frédéric|Nussbaum, Louis-Frédéric]], 2002: [https://books.google.com/books?id=p2QnPijAEmEC&pg=PA780 "Provinces and prefectures"] in ''Japan encyclopedia'', p.&nbsp;780.</ref>

Each prefecture's chief executive is a [[Direct election|directly elected]] {{nihongo|[[Governor (Japan)|governor]]|知事|chiji}}. [[Local ordinance|Ordinance]]s and budgets are enacted by a [[unicameral]] {{nihongo|assembly|議会|gikai}} whose members are elected for four-year terms.

Under a set of 1888–1890 laws on local government<ref>{{nihongo|{{ill|prefectural code|ja|府県制}}|府県制|fukensei}}, {{nihongo|{{ill|district code|ja|郡制}}|郡制|gunsei}}, {{nihongo|{{ill|City code (Japan)|ja|市制|lt=city code}}|市制|shisei}}, {{nihongo|{{ill|town and village code|ja|町村制}}|町村制|chōsonsei}}</ref> until the 1920s, each prefecture (then only 3 ''-fu'' and 42 ''-ken''; ''Hokkaidō'' and ''Okinawa-ken'' were subject to different laws until the 20th century) was subdivided into {{nihongo|cities|市|shi}} and {{nihongo|districts|郡|gun}} and each district into {{nihongo|towns|町|chō/machi}} and {{nihongo|villages|村|son/mura}}. [[Hokkaido|Hokkaidō]] has 14 [[Subprefectures of Hokkaido|subprefectures]] that act as  {{nihongo|General Subprefectural Bureaus|総合振興局|sōgō-shinkō-kyoku, "Comprehensive Promotion Bureau"}} and {{nihongo|Subprefectural Bureaus|振興局|shinkō-kyoku, "Promotion Bureau"}} of the prefecture. Some other prefectures also have branch offices that carry out prefectural administrative functions outside the capital. [[Tokyo]], the [[capital of Japan]], is a merged city-prefecture; a metropolis, it has features of both cities and prefectures.

Each prefecture has its own [[Mon (emblem)|mon]] for identification, the equivalent of a coat of arms in the West.

== Background ==
{{Administrative divisions of Japan}}

The West's use of "prefecture" to label these Japanese regions stems from 16th-century Portuguese explorers and [[Nanban trade|traders]] use of "prefeitura" to describe the [[fief]]doms they encountered there.{{citation needed|date=February 2021}} Its original sense in Portuguese, however, was closer to "[[Municipalities of Portugal|municipality]]" than "[[Provinces of Portugal|province]]". Today, in turn, Japan uses its word ''ken'' ({{lang|ja|県}}), meaning "prefecture", to identify [[Districts of Portugal|Portuguese districts]] while in Brazil the word "Prefeitura" is used to refer to a [[city hall]].

Those fiefs were headed by a local warlord or family. Though the fiefs have long since been dismantled, merged, and reorganized multiple times, and been granted legislative governance and oversight, the rough translation stuck.

The [[Government of Meiji Japan|Meiji government]] established the current system in July 1871 with the [[abolition of the han system]] and establishment of the {{Nihongo|prefecture system|廃藩置県|haihan-chiken}}. Although there were initially over 300 prefectures, many of them being former [[Han (administrative division)|han]] territories, this number was reduced to 72 in the latter part of 1871, and 47 in 1888. The [[Local Autonomy Law]] of 1947 gave more political power to prefectures, and installed prefectural governors and parliaments.

In 2003, [[Prime Minister of Japan|Prime Minister]] [[Junichiro Koizumi]] proposed that the government [[Merger and dissolution of municipalities of Japan|consolidates the current prefectures]] into about 10 regional states (so-called ''[[dōshūsei]]''). The plan called for each region to have greater autonomy than existing prefectures. This process would reduce the number of subprefecture administrative regions and cut administrative costs.<ref>Mabuchi, Masaru, [http://siteresources.worldbank.org/WBI/Resources/wbi37175.pdf "Municipal Amalgamation in Japan"] {{Webarchive|url=https://web.archive.org/web/20151106103204/http://siteresources.worldbank.org/WBI/Resources/wbi37175.pdf |date=2015-11-06 }}, World Bank, 2001.</ref> The Japanese government also considered a plan to merge several groups of prefectures, creating a subnational administrative division system consisting of between nine and 13 states, and giving these states more local autonomy than the prefectures currently enjoy.<ref>[http://www.nira.go.jp/publ/seiken/ev18n10/ev18n10-s.html "''Doshusei'' Regional System"] {{webarchive|url=https://web.archive.org/web/20060926160741/http://www.nira.go.jp/publ/seiken/ev18n10/ev18n10-s.html |date=2006-09-26 }} National Association for Research Advancement.</ref> As of August 2012, this plan was abandoned.

== Powers ==
{{main|Government of Japan#Local government}}
Japan is a [[unitary state]]. The central government delegates many functions (such as [[Education in Japan|education]] and the [[Law enforcement in Japan|police force]]) to the prefectures and [[Municipalities of Japan|municipalities]], but retains the overall right to control them. Although local government expenditure accounts for 70 percent of overall [[government expenditure]], the central government controls local budgets, [[tax rate]]s, and borrowing.<ref>Mochida, "Local Government Organization and Finance: Japan", in {{cite book |title=Local Governance in Industrial Countries |first=Anwar |last=Shah |year=2006 |publisher=World Bank |url=http://web.worldbank.org/WBSITE/EXTERNAL/WBI/WBIPROGRAMS/PSGLP/0,,contentMDK:21215193~pagePK:64156158~piPK:64152884~theSitePK:461606~isCURL:Y,00.html |access-date=2013-12-01 |archive-date=2014-01-08 |archive-url=https://web.archive.org/web/20140108175935/http://web.worldbank.org/WBSITE/EXTERNAL/WBI/WBIPROGRAMS/PSGLP/0,,contentMDK:21215193~pagePK:64156158~piPK:64152884~theSitePK:461606~isCURL:Y,00.html |url-status=live }}</ref>

Prefectural government functions include the organization of the prefectural police force, the supervision of schools and the maintenance of prefectural schools (mainly high schools), prefectural hospitals, [[prefectural road]]s, the supervision of prefectural waterways and regional urban planning. Their responsibilities include tasks delegated to them by the national government such as maintaining most ordinary national roads (except in designated major cities), and prefectures coordinate and support their municipalities in their functions. De facto, prefectures as well as municipalities have often been less autonomous than the formal extent of the local autonomy law suggests, because of national funding and policies. Most of municipalities depend heavily on central government funding – a dependency recently further exacerbated in many regions by the declining population which hits rural areas harder and earlier (cities can offset it partly through migration from the countryside). In many policy areas, the basic framework is set tightly by national laws, and prefectures and municipalities are only autonomous within that framework.

== Types of prefecture ==
Historically, during the [[Edo period]], the [[Tokugawa shogunate]] established {{Nihongo|''bugyō''-ruled zones|奉行支配地}} around the nine largest cities in Japan, and 302 {{Nihongo|township-ruled zones|郡代支配地}} elsewhere. When the Meiji government began to create the prefectural system in 1868, the nine bugyō-ruled zones became {{Nihongo|''fu''|府}}, while the township-ruled zones and the rest of the bugyō-ruled zones became {{Nihongo|''ken''|県}}. Later, in 1871, the government designated [[Tokyo]], [[Osaka Prefecture|Osaka]], and [[Kyoto Prefecture|Kyoto]] as ''fu'', and relegated the other ''fu'' to the status of ''ken.'' During [[World War II]], in 1943, Tokyo became a ''to,'' a new type of pseudo-prefecture.

Despite the differences in terminology, there is little functional difference between the four types of local governments. The subnational governments are sometimes collectively referred to as {{nihongo|''todōfuken''|[[wikt:都道府県|都道府県]]||{{IPA|ja|todoːɸɯ̥ꜜkeɴ|}}}} in Japanese, which is a combination of the four terms.

===''To''===
[[Tokyo]], [[capital city]] of Japan is referred to as {{Nihongo|''to''|都||{{IPA|ja|toꜜ|}}}}, which is often translated as "metropolis". The Japanese government translates {{Nihongo|''Tōkyō-to''|東京都||{{IPA|ja|toːkʲoꜜːto|}}}} as "Tokyo Metropolis" in almost all cases, and the government is officially called the "Tokyo Metropolitan Government".

Following the capitulation of the [[Tokugawa shogunate]] in 1868, ''Tōkyō-fu'' (an urban prefecture like Kyoto and Osaka) was set up and encompassed the former city area of Edo under the [[Fuhanken sanchisei]]. After the [[abolition of the han system]] in the first wave of prefectural mergers in 1871/72, several surrounding areas (parts of [[Urawa prefecture|Urawa]], [[Kosuge prefecture|Kosuge]], [[Shinagawa prefecture|Shinagawa]] and [[Hikone domain|Hikone prefecture]]s) were merged into Tokyo, and under the system of (numbered) "large districts and small districts" ''(daiku-shōku)'', it was subdivided into eleven large districts further subdivided into 103 small districts, six of the large districts (97 small districts) covered the former city area of Edo.<ref>National Archives of Japan: [http://www.archives.go.jp/exhibition/digital/henbou/contents/11.html 『明治東京全図』] {{Webarchive|url=https://web.archive.org/web/20230102061207/https://www.archives.go.jp/exhibition/digital/henbou/contents/11.html |date=2023-01-02 }}</ref> When the ancient ritsuryō districts were reactivated as administrative units in 1878, Tokyo was subdivided into 15 [urban] districts ''(-[[Cities of Japan (1878–1889)|ku]])'' and initially six [rural] districts (''-[[Districts of Japan|gun]]''; nine after the [[Western Tokyo|Tama transfer]] from [[Kanagawa prefecture|Kanagawa]] in 1893, eight after the merger of [[Higashitama district, Tokyo|East Tama]] and [[Minamitoshima district, Tokyo|South Toshima]] into [[Toyotama district, Tokyo|Toyotama]] in 1896). Both urban and rural districts, like everywhere in the country, were further subdivided into urban units/towns/neighbourhoods ''(-chō/-machi)'' and rural units/villages ''(-mura/-son)''. The yet unincorporated communities on the Izu (previously part of [[Shizuoka prefecture|Shizuoka]]) and Ogasawara (previously directly Home Ministry-administrated) island groups became also part of Tokyo in the 19th century. When the modern municipalities – [district-independent] cities and [rural] districts containing towns and villages – were introduced under the [[Yamagata Aritomo|Yamagata]]-[[Albert Mosse|Mosse]] laws on local government and the simultaneous Great Meiji merger was performed in 1889, the 15 ''-ku'' became wards of [[Tokyo City]], initially Tokyo's only independent city ''(-shi)'', the six rural districts of Tokyo were consolidated in 85 towns and villages.<ref>Tokyo Metropolitan Archives: [http://www.soumu.metro.tokyo.jp/01soumu/archives/0714tokyo_ku.htm 大東京35区物語～15区から23区へ～東京23区の歴史] {{Webarchive|url=https://web.archive.org/web/20071117143917/http://www.soumu.metro.tokyo.jp/01soumu/archives/0714tokyo_ku.htm |date=2007-11-17 }}</ref> In 1893, the three Tama districts and their 91 towns and villages became part of Tokyo. As Tokyo city's suburbs grew rapidly in the early 20th century, many towns and villages in Tokyo were merged or promoted over the years. In 1932, five complete districts with their 82 towns and villages were merged into Tokyo City and organised in 20 new wards. Also, by 1940, there were two more cities in Tokyo: [[Hachiōji, Tokyo|Hachiōji City]] and [[Tachikawa, Tokyo|Tachikawa City]].

In 1943, Tokyo City was abolished, ''Tōkyō-fu'' became ''Tōkyō-to'', and Tokyo-shi's 35 wards remained Tokyo-to's 35 wards, but submunicipal authorities of Tokyo-shi's wards which previously fell directly under the municipality, with the municipality now abolished, fell directly under prefectural or now "Metropolitan" authority. All other cities, towns and villages in Tokyo-fu stayed cities, towns and villages in Tokyo-to. The reorganisation's aim was to consolidate the administration of the area around the capital by eliminating the extra level of authority in Tokyo. Also, the governor was no longer called ''chiji'', but ''chōkan'' (~"head/chief [usually: of a central government agency]") as in Hokkaidō). The central government wanted to have greater control over all local governments due to Japan's deteriorating position in World War II – for example, all mayors in the country became appointive as in the Meiji era – and over Tokyo in particular, due to the possibility of emergency in the metropolis.

After the war, Japan was forced to decentralise Tokyo again, following the general terms of democratisation outlined in the [[Potsdam Declaration]]. Many of Tokyo's special governmental characteristics disappeared during this time, and the wards took on an increasingly municipal status in the decades following the surrender. Administratively, today's special wards are almost indistinguishable from other municipalities.

The postwar reforms also changed the map of Tokyo significantly: In 1947, the 35 wards were reorganised into the [[23 special wards]], because many of its citizens had either died during the war, left the city, or been drafted and did not return.{{citation needed|date=April 2013}} In the occupation reforms, special wards, each with their own elected assemblies (''kugikai'') and mayors (''kuchō''), were intended to be equal to other municipalities even if some restrictions still applied. (For example, there was during the occupation [[Tokyo Metropolitan Police|a dedicated municipal police agency for the 23 special wards/former Tokyo City]], yet the special wards public safety commission was not named by the special ward governments, but by the government of the whole "Metropolis". In 1954, independent municipal police forces were abolished generally in the whole country, and the prefectural/"Metropolitan" police of Tokyo is again responsible for the whole prefecture/"Metropolis" and like all prefectural police forces controlled by the prefectural/"Metropolitan" public safety commission whose members are appointed by the prefectural/"Metropolitan" governor and assembly.) But, as part of the "reverse course" of the 1950s some of these new rights were removed, the most obvious measure being the denial of directly elected mayors. Some of these restrictions were removed again over the decades. But it was not until the year 2000 that the special wards were fully recognised as municipal-level entities.

Independently from these steps, as Tokyo's urban growth again took up pace during the postwar economic miracle and most of the main island part of Tokyo "Metropolis" became increasingly core part of the [[Tokyo metropolitan area]], many of the other municipalities in Tokyo have transferred some of their authority to the Metropolitan government. For example, the [[Tokyo Fire Department]] which was only responsible for the 23 special wards until 1960 has until today taken over the municipal fire departments in almost all of Tokyo. A joint governmental structure for the whole Tokyo metropolitan area (and not only the western suburbs of the special wards which are part of the Tokyo prefecture/Metropolis") as advocated by some politicians such as former Kanagawa governor [[Shigefumi Matsuzawa]]<ref>The Japan Times, 4 December 2003: [http://www.japantimes.co.jp/news/2003/12/04/national/few-warm-to-greater-tokyo-assembly-idea/ Few warm to greater-Tokyo assembly idea.

There are some differences in terminology between Tokyo and other prefectures: police and fire departments are called {{Nihongo|''chō''|庁}} instead of {{Nihongo|''honbu''|本部}}, for instance. But the only functional difference between Tōkyō-to and other prefectures is that Tokyo administers wards as well as cities. Today, since the special wards have almost the same degree of independence as Japanese cities, the difference in administration between Tokyo and other prefectures is fairly minor.

In Osaka, several prominent politicians led by [[Tōru Hashimoto]], then mayor of [[Osaka|Osaka City]] and former governor of [[Osaka Prefecture]], proposed an [[Osaka Metropolis plan]], under which Osaka City, and possibly other neighboring cities, would be replaced by special wards similar to Tokyo's. The plan was narrowly defeated in [[2015 Osaka Metropolis Plan referendum|a 2015 referendum]], and again [[2020 Osaka Metropolis Plan referendum|in 2020]].<ref>{{cite news |title=Osaka metropolis plan rejected by slim margin in 2nd referendum |url=https://english.kyodonews.net/news/2020/11/602c90c5b457-voting-begins-in-2nd-referendum-on-osaka-metropolis-plan.html |access-date=14 July 2021 |agency=Kyodo News |date=2 November 2020 |archive-date=28 July 2021 |archive-url=https://web.archive.org/web/20210728124533/https://english.kyodonews.net/news/2020/11/602c90c5b457-voting-begins-in-2nd-referendum-on-osaka-metropolis-plan.html |url-status=live }}</ref>

===''Dō''===
[[Hokkaido|Hokkaidō]] is referred to as a {{Nihongo|''dō''|道||{{IPA|ja|doꜜː|}}}} or [[Circuit (administrative division)|circuit]]. This term was originally used to refer to Japanese regions consisting of several [[Provinces of Japan|provinces]] (e.g. the [[Tōkaidō (region)|Tōkaidō]] east-coast region, and [[Saikaido]] west-coast region). This was also a historical usage of the character in China. (In Korea, this historical usage is still used today and was kept during the [[Korea under Japanese rule|period of Japanese rule]].)

{{Nihongo|''Hokkai-dō''|北海道||{{IPA|ja|hokkaꜜidoː|}}}}, the only remaining ''dō'' today, was not one of the original seven ''dō'' (it was known as [[Ezo]] in the pre-modern era). Its current name is believed to originate from [[Matsuura Takeshirō|Matsuura Takeshiro]], an early Japanese explorer of the island. Since Hokkaidō did not fit into the existing ''dō'' classifications, a new ''dō'' was created to cover it.

The Meiji government originally classified Hokkaidō as a {{Nihongo|"Settlement Envoyship"|開拓使|kaitakushi}}, and later divided the island into three prefectures (Sapporo, Hakodate, and Nemuro). These were consolidated into a single {{Nihongo|Hokkaido Department|北海道庁|Hokkaido-chō}} in 1886, at prefectural level but organized more along the lines of a territory. In 1947, the department was dissolved, and Hokkaidō became a full-fledged prefecture. The ''-ken'' suffix was never added to its name, so the ''-dō'' suffix came to be understood to mean "prefecture".

When Hokkaidō was incorporated, transportation on the island was still underdeveloped, so the prefecture was split into several {{Nihongo|"subprefectures"|支庁 |shichō}} that could fulfill administrative duties of the prefectural government and keep tight control over the developing island. These subprefectures still exist today, although they have much less power than they possessed before and during World War II. They now exist primarily to handle paperwork and other bureaucratic functions.

"Hokkaidō Prefecture" is, technically speaking, a redundant term because ''dō'' itself indicates a prefecture, although it is occasionally used to differentiate the government from the island itself. The prefecture's government calls itself the "Hokkaidō Government" rather than the "Hokkaidō Prefectural Government".

===''Fu''===
[[Osaka Prefecture|Osaka]] and [[Kyoto Prefecture|Kyoto]] Prefectures are referred to as {{Nihongo|''fu''|府||pronounced {{IPA|ja|ɸɯꜜ|}} when a separate word, but {{IPA|ja|ꜜɸɯ|}} when part of the full name of a prefecture, e.g. {{IPA|ja|kʲoꜜːto|}} and {{IPA|ja|ɸɯꜜ|}} become {{IPA|ja|kʲoːtoꜜɸɯ|}}}}. The Classical Chinese character from which this is derived implies a core urban zone of national importance. Before World War II, different laws applied to ''fu'' and ''ken,'' but this distinction was abolished after the war, and the two types of prefecture are now functionally the same.

===''Ken''===
43 of the 47 prefectures are referred to as {{Nihongo|''ken''|県||pronounced {{IPA|ja|keꜜɴ|}} when a separate word but {{IPA|ja|ꜜkeɴ|}} when part of the full name of a prefecture, e.g. {{IPA|ja|aꜜitɕi|}} and {{IPA|ja|keꜜɴ|}} become {{IPA|ja|aitɕi̥ꜜkeɴ|}}}}. The Classical Chinese character from which this is derived carries a rural or provincial connotation, and an analogous character is used to refer to the [[counties of China]], [[County (Taiwan)|counties of Taiwan]] and [[District (Vietnam)|districts of Vietnam]].

Before the post-war treaties were to be signed by the ROC and Japan, the ROC government was defeated in the [[Chinese Civil War]] to the [[Chinese Communist Party]] (CCP) and decamped to the island of Taiwan. Japan relinquished the claims to Taiwan and Penghu in the [[Treaty of San Francisco]] on 28 April 1952, but the sovereignty of the islands remained undetermined to this day. Excluding Kinmen and Matsu, which form the rump Fujian Province, Taiwan and Penghu are still today governed by the Republic of China in a post-war capacity recognized by a few states as the sole legitimate government of "China".
