[[ThirtySecondsOverTokyo Contrary to]] [[TokyoIsTheCenterOfTheUniverse popular belief]], Japan is not only UsefulNotes/{{Tokyo}}. There are 46 other prefectures that the country is divided into, which are in turn (for the most part) divided further into cities and districts; districts are further subdivided into towns and villages. Prefectures are largely dependent on the national government in Tokyo for financial support and their organization is defined by the Local Autonomy Law, which went into effect in 1947. Prefectures, however, elect their own governors and do get some autonomy in their policy-making. If you're familiar with how the American government is set up, an oft-used analogy is the relationship between [[UsefulNotes/AmericanPoliticalSystem the county and the state it's part of]].

The current prefectural system was developed out of the UsefulNotes/MeijiRestoration in 1868; prior to that Japan was divided into provinces, which weren't legally the fiefdoms the local daimyo ruled over as feudal lords but for administrative purposes ended up as the same thing. Technically, the provinces of Japan were never abolished (what was abolished was the ''-han'' fiefdom system that the local daimyo actually ruled, which ran concurrent to the provinces - the current prefectures came from a couple rounds of consolidating some 300 ''han'') but nowadays are chiefly used for local-branding purposes. There's a good deal of overlap between the boundaries in both systems, though - if you compare a map of Japan's feudal provinces with a map of its modern prefectures, their borders don't deviate all that much from each other (the big exception is the Tohoku region, where two provinces are now six prefectures).

A note about titles - there's not one single title used in Japanese for all 47 of them. The Western standard of calling Japan's subdivisions "prefectures" is from Portuguese contact in the 15th Century, who called the fiefdoms ruled by the various daimyo ''prefeitura''. Japan currently has four different designations for its first-level political subdivisions, the titles borrowed from Imperial Chinese administration organization. After the Meiji Restoration each type of prefecture had their own set of administrative powers, though since WorldWarTwo the differences have largely become inconsequential:

* Tokyo is a -''to'' (都). Tōkyō-to is usually translated as "Tokyo Metropolis", reflecting the fact that it has grown even higher than its erstwhile peers in Osaka and Kyoto in terms of importance.
* Hokkaido is a -"dō" (道), which translates as "circuit". It is a remainder from the Asuka ([[NeonGenesisEvangelion no, not that one]]) Period (538-710 AD), when Japan was divided into Gokishichidō: five provinces centered around the Imperial capital Nara and later Kyoto (Kinai), and seven circuits based on the roads that connected them to those five central provinces. (Hokkaido was not one of those original seven circuits - it's basically a -''dō'' because the Meiji Government didn't know what else to call it as it wasn't developed enough to be a -''ken''.)
* Osaka and Kyoto Prefectures are titled with -''fu'' (府). In Imperial China, it implied the subdivision in question was an urban center of national importance - given that for most of Japanese history Kyoto was where the Emperor resided and Osaka was the largest trading center in the country (especially for rice), it seems justified. After the Meiji Restoration Tokyo was also a -''fu'' until the national government made it a ''-to'' in 1943 in order to retain more control over the largest urban area in the country when WorldWarTwo was turning against them.
* The other 43 prefectures are officially called -''ken'' (県). Prefectures being styled with this implies that the prefecture is a more rural area.

All 47 prefectural governments are sometimes collectively referred to as ''to-dō-fu-ken'' (都道府県).

Prefectures are organized by region[[note]]Regions have no legal standing in Japan - they just developed out of customarily-used groups of prefectures among businesses and government organizations[[/note]] and are numbered in order of ISO ordering. Listed populations are estimates as of October 1, 2011.

[[folder:Hokkaido (北海道)]]

1. '''Hokkaido (北海道)'''
->Capital: Sapporo (札幌)
->Other cities of note: Asahikawa (旭川), Hakodate (函館)
->Population: 5,485,952 (8th)

Literally translates as "Northern Sea Circuit". Hokkaido is physically the northernmost of the four main islands. As mentioned above, the "-do" indicates the type of prefecture it is, so "Hokkaido Prefecture" is technically redundant unless you want to distinguish between the island and the political entity. The prefecture also includes several small islands around it (including, officially, [[http://en.wikipedia.org/wiki/Kuril_Islands_dispute four that were seized by the Soviet Union]] at the end of WorldWarTwo and are a major reason why Japan and Russia do not currently have a formal peace treaty). Due to its late development and relatively large size with many sparsely-populated areas, rather than cities and districts Hokkaido is subdivided into subprefectures which handle the local administrative work.

Historically called Ezo (蝦夷)[[note]]"Ezo" and "Hokkaido" don't always refer to the same place - "Ezo" refers to lands north of traditional Japanese settlement and may mean as far as the Kuril Islands and Sakhalin[[/note]], the island was for most of its history inhabited by Ainu - the cold, snowy winters discouraged large-scale Japanese settlement beyond the southern tip through most of Feudal Japan's history, and for the most part whatever shogunate was in power was content to let the Matsumae clan have feudal domain over the Ainu and retain a monopoly on trade with them. It wasn't until after Commodore Perry's black ships arrived and the shogunate began modernization efforts did control of Hokkaido tighten, mainly to stop the Russians from taking it for themselves for their own Far East expansion.

Hakodate was the LastStand of the Tokugawa Shogunate following the Meiji Restoration in 1868 - a bunch of shogunate loyalists took over the fort there and held out until they were crushed the following May. The Meiji government took up the task of developing Hokkaido and brought in help from American advisors - the effects can be seen today in much of Hokkaido's historical architecture, which look more like something you'd see in the American Midwest, and the Western grid-pattern street layout of Sapporo (the only other Japanese cities to have such a layout are Kyoto and Nara).

Today, it's probably most well-known for its tourism opportunities, whether it's being able to escape the monsoon rains that drench the rest of Japan in the humid months of June and July, or the skiing opportunites in the winter (Sapporo hosted the 1972 Winter Olympics), or the many hot springs and natural landmarks all over the island. It's also known for its diverse array of agricultural products - Hokkaido has about a quarter of all the arable land in Japan.

[[/folder]]

[[folder:Tōhoku (東北)]]

In the northeastern part of Honshū, north of the Kanto Plain lies the Tohoku Region; "Tōhoku" literally translates as [[ExactlyWhatItSaysOnTheTin "east-north"]]. Historically this is a less-developed region, as it was settled by Japanese centuries after the center of its civilization developed to the south. The mountainous geography of the area, the rather harsh winters, and the relative lack of easy transport access (by road or by sea - the rivers generally aren't suitable for boats and there aren't many harbors) further slowed settlement. Despite the relatively short growing season, the region is now known as an agricultural center, as a disproportionate amount of the nation's rice is grown here as similar populated areas in the south went for industrialization first. This combination of factors is likely why someone with a TohokuRegionalAccent gets stereotyped as a backwoods hillbilly.

During the age of the Shogun, this whole region of six current prefectures was made up of just two provinces (Dewa and Mutsu) because of its relative lack of development, and the comparitive remoteness from the rest of Japanese civilization meant the local clans (most notably the [[UsefulNotes/DateMasamune Date]] family) always maintained some distance and autonomy from the center of power in Kyoto or Edo.

This is the region that was devastated the most by the March 2011 earthquake and ensuing tsunami and nuclear reactor meltdown - the epicenter of the earthquake was about 72 kilometers[[note]]about 45 miles[[/note]] off the coast of Miyagi Prefecture.

[[folder:Kantō (関東)]]

"Kanto" literally translates as "East of the Barrier" - the "Barrier" in question was the Hakone (箱根) Checkpoint, a town located at the very western edge of present-day Kanagawa Prefecture and marked the point at which Tokugawa Shogunate officials would stop and check travelers from points west in order to enforce restrictions on the movement of women and weapons. The area itself has the Kanto Plain, which makes up about half the region and is the single largest plain in Japan. The plain is fed by many rivers that flow through it - this combined with the fact that arable land is at premium in a country that is 90% mountain made it a very lucrative location for Tokugawa Ieyasu to establish his center of power in 1603.

The Kanto region was the heart of feudal Japan's power during the Kamakura Period (1185-1333), partly thanks to the resident Hojo clan who helped the Minamoto clan establish a shogunate over the rest of Japan and later seized control of the shogunate with some slick backroom politics. In the UsefulNotes/SengokuJidai, an unrelated line of daimyo took the Hojo name and seized power in the region, ruling from Odawara. Kanto became the seat of shogunate power again during the Edo Period (1603-1867), remaining so after the Meiji Restoration with the Emperor physically moving from Kyoto to the now-renamed Tokyo. Tokyo and Yokohama were major industrial centers that attracted large numbers of migrants, even with the Great Kanto Earthquake of 1923 resulting in over 100,000 dead.

With about 1/3 of Japan's entire population (and Tokyo's metropolitan area still growing in a country whose national population is starting to decline), as well as the modern center of the nation's politics, business, and culture, this will most certainly remain the most prominent region of Japan for the foreseeable future.

8. '''Ibaraki (茨城)'''
-> Capital: Mito (水戸)
-> Population: 2,957,706 (11th)

Historically known as Hitachi Province. Yes, as in the Hitachi company that might have made your TV or air conditioner - the company was founded in the namesake town located in the prefecture in 1910.

[[folder:Chūbu (中部)]]

This is a fairly diverse group of prefectures encompassing the general area between the Kanto and Kansai regions. It's often subdivided into three subregions:

!!Hokuriku (北陸地)
These four prefectures lie on the coast of the Sea of Japan. During the winter air from Siberia picks up moisture travelling across the Sea of Japan before it is forced upward by the Japanese Alps and causing it to dump its precipitation, making this area among the snowiest places on Earth.

15. '''Niigata (新潟)'''

-> Population: 2,362,158 (14th)

16. '''Toyama (富山)'''

-> Population: 1,166,309 (34th)

18. '''Fukui (福井)'''
-> Capital: Fukui
-> Population: 802,906 (43rd)

!!Kōshin'etsu (甲信)
This region encompasses the most mountainous parts of the Japanese Alps, and most of its population is concentrated in basins scattered throughout. Historically the area was known for its silk production; nowadays more of its population is involve in light manufacturing.

Niigata is sometimes included in this group.

19. '''Yamanashi (山梨)'''
-> Capital: Kōfu (甲府)
-> Population: 857,459 (41st)

Directly to the west of Tokyo, Yamanashi includes the northern slopes of Mount Fuji. Historically known as Kai Province, home of the [[UsefulNotes/TakedaShingen Takeda]] clan.

20. '''Nagano (長野)'''
-> Capital: Nagano
-> Population: 2,142,167 (16th)

The 1998 Winter Olympics were held here.

!!!Gifu

21. '''Gifu (岐阜)'''
-> Capital: Gifu
-> Population: 2,070,908 (17th)

Gifu Prefecture itself is usually not considered a part of any of the three subregions listed on this page. When it does get classified it's often split, with its mountainous northern half (formerly Hida Province) going to the Kōshin'etsu region and the southern plain near Nagoya (formerly Mino Province) grouped into the Tōkai region. The namesake town's central location near the main routes to and from Kyoto made it a key strategic point during the Sengoku Period - as the saying goes, "control Gifu and you control Japan."

!!Tōkai (東海)
The name itself means "east sea", and refers to one of the seven circuits of the Gokishichidō - the Tōkaidō region stretched from the Kansai Plain and ran along the Pacific coast all the way to present-day Ibaraki Prefecture. The Tōkaidō Road, meanwhile, was the road that the Hakone Checkpoint (see the Kanto region) sat on, being the most important road of the Edo Period and today is still the most heavily travelled route in Japan thanks to all the industry that it served by it.

Mie Prefecture (listed here under Kansai) and the southern half of Gifu Prefecture are often considered part of this subregion. The Chūkyō (中京) Metropolitan Area (Shizuoka, Aichi, and Mie) centered around Nagoya are especially close economically.

22. '''Shizuoka (静岡)'''
-> Capital: Shizuoka
-> Population: 3,749,274 (10th)

Includes the southern slopes of Mount Fuji as well as the hilly Izu Peninusula, popular for its hot springs.

23. '''Aichi (愛知)'''
-> Capital: Nagoya (名古屋)
-> Population: 7,416,336 (4th)

[[folder:Kansai (関西)]]
"West of the Barrier", though the barrier in this case was the Osaka Tollgate on the border of present-day Kyoto and Shiga Prefectures. This is the historical center of Japanese civilization and today remains the biggest counterpart to Tokyo and the Kanto region. The Kinki (近畿) region is more or less synonymous with Kansai, though it generally excludes Mie.

24. '''Mie (三重)'''
-> Capital: Tsu (津)
-> Population: 1,847,223 (22nd)

25. '''Shiga (滋賀)'''

Centered around Lake Biwa, the largest inland body of water in Japan.

26. '''Kyōto (京都)'''
-> Capital: Kyōto
-> Population: 2,631,671 (13th)

The historical heart of Japan, partly thanks to being the Imperial seat from 794 until the Emperor Meiji moved it to Tokyo in 1868. The Emperor may not have had much meaningful political power for most of Japan's history, but its contribution to traditional Japanese culture today is immensive - ''Literature/TheTaleOfGenji'' (sometimes considered the world's first modern novel), noh and kabuki theater, around 2000 temples, highly-regarded kimonos, sake production, etc. The city largely escaped aerial bombing by YanksWithTanks during WorldWarTwo; it was on the list of potential atomic bomb targets but Secretary of War Henry L. Stimson got the city removed from the list because he had fond memories from his honeymoon there (it was replaced by Nagasaki).

The combination of all these factors meant that Kyoto emerged post-war with probably the highest concentration of traditional Japanese architechture such as ''machiya'' in the country. However, with all the historic and cultural prizes the city has don't think that the city is stuck in the past - modernization is quickly replacing old buildings with newer archtecture (case in point: the new Kyoto Station) and information technology is a major part of the economy. Oh, and {{Creator/Nintendo}} is based here, too.

Fun urban-planning fact - until Sapporo developed Kyoto and Nara were the only Japanese cities with a grid pattern for its streets. While Sapporo's grid was a result of its development being advised by Americans, Kyoto's was the result of Chinese feng-shui philosophy which also oriented the streets so that the old Imperial Palace faced south. Pretty much every other city in Japan has streets that cross and meet each other at irregular angles, mainly to confuse rival daimyo who might try to take over their turf.

Though the name "Chūgoku" literally means mid-country (and also happens to be the Japanese word for China), the region occupies the western part of Honshu. The region can be split in half down its mountainous middle, with the San'in (山陰) region bordering the Sea of Japan and the San'yō (山陽) region bordering the Inland Sea. (Portions of Hyōgo and Kyōto prefectures were historically also part of the San'in and San'yō regions.)
