Tokyo (東京, Tōkyō, "Eastern Capital") (Japanese: [toːkjoː], English /ˈtoʊki.oʊ/), officially Tokyo Metropolis (東京都, Tōkyō-to), is one of the 47 prefectures of Japan, and is both the capital and most populous city of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world. It is the seat of the Emperor of Japan and the Japanese government. Tokyo is in the Kantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. Formerly known as Edo, it has been the de facto seat of government since 1603 when Shogun Tokugawa Ieyasu made the city his headquarters. It officially became the capital after Emperor Meiji moved his seat to the city from the old capital of Kyoto in 1868; at that time Edo was renamed Tokyo. Tokyo Metropolis was formed in 1943 from the merger of the former Tokyo Prefecture (東京府, Tōkyō-fu) and the city of Tokyo (東京市, Tōkyō-shi).

Tokyo is often referred to as a city, but is officially known and governed as a "metropolitan prefecture", which differs from and combines elements of both a city and a prefecture, a characteristic unique to Tokyo. The Tokyo metropolitan government administers the 23 Special Wards of Tokyo (each governed as an individual city), which cover the area that was formerly the City of Tokyo before it merged and became the subsequent metropolitan prefecture in 1943. The metropolitan government also administers 39 municipalities in the western part of the prefecture and the two outlying island chains. The population of the special wards is over 9 million people, with the total population of the prefecture exceeding 13 million. The prefecture is part of the world's most populous metropolitan area with upwards of 37.8 million people and the world's largest urban agglomeration economy. The city hosts 51 of the Fortune Global 500 companies, the highest number of any city in the world. Tokyo ranked third in the International Financial Centres Development IndexEdit. The city is also home to various television networks like Fuji TV, Tokyo MX, TV Tokyo, TV Asahi, Nippon Television, NHK and the Tokyo Broadcasting System.

Tokyo ranked fifth in the Global Economic Power Index and fourth in the Global Cities Index. The city is considered an alpha+ world city – as listed by the GaWC's 2008 inventory – and in 2014, Tokyo was ranked first in the "Best overall experience" category of TripAdvisor's World City Survey (the city also ranked first in the following categories: "helpfulness of locals", "nightlife", "shopping", "local public transportation" and "cleanliness of streets"). In 2015, Tokyo was ranked as the 11th most expensive city for expatriates, according to the Mercer consulting firm, and also the world's 11th most expensive city, according to the Economist Intelligence Unit's cost-of-living survey. In 2015, Tokyo was named the Most Liveable City in the world by the magazine Monocle. The Michelin Guide has awarded Tokyo by far the most Michelin stars of any city in the world. Tokyo ranked first in the world in the Safe Cities Index. The 2016 edition of QS Best Student Cities ranked Tokyo as the 3rd-best city in the world to be a university student. Tokyo hosted the 1964 Summer Olympics, the 1979 G-7 summit, the 1986 G-7 summit, and the 1993 G-7 summit, and will host the 2020 Summer Olympics and the 2020 Summer Paralympics.

Etymology

Tokyo was originally known as Edo (江戸), which means "estuary". Its name was changed to Tokyo (東京 Tōkyō; 東 tō "east", and 京 kyō "capital") when it became the imperial capital with the arrival of Emperor Meiji in 1868, in line with the East Asian tradition of including the word capital (京) in the name of the capital city. During the early Meiji period, the city was also called "Tōkei", an alternative pronunciation for the same Chinese characters representing "Tokyo", making it a kanji homograph. Some surviving official English documents use the spelling "Tokei". However, this pronunciation is now obsolete.

The name Tokyo was first suggested in 1813 in the book Kondō Hisaku (Secret Plan of Commingling), written by Satō Nobuhiro. When Ōkubo Toshimichi proposed the renaming to the government during the Meiji Restoration, according to Oda Kanshi (織田完之), he got the idea from that book.

History

Pre-1869 (Edo Period)

Tokyo was originally a small fishing village named Edo, in what was formerly part of the old Musashi Province. Edo was first fortified by the Edo clan, in the late twelfth century. In 1457, Ōta Dōkan built Edo Castle. In 1590, Tokugawa Ieyasu made Edo his base. When he became shogun in 1603, the town became the center of his nationwide military government. During the subsequent Edo period, Edo grew into one of the largest cities in the world with a population topping one million by the 18th century. Edo became the de facto capital of Japan even while the emperor lived in Kyoto, the imperial capital. During this time, the city enjoyed a prolonged period of peace known as the Pax Tokugawa, and in the presence of such peace, Edo adopted a stringent policy of seclusion, which helped to perpetuate the lack of any serious military threat to the city. The absence of war-inflicted devastation allowed Edo to devote the majority of its resources to rebuilding in the wake of the consistent fires, earthquakes, and other devastating natural disasters that plagued the city. However, this prolonged period of seclusion came to an end with the arrival of American Commodore, Matthew C. Perry in 1853. Commodore Perry negotiated the opening of the ports of Shimoda and Hakodate, leading to an increase in the demand for new foreign goods and subsequently a severe rise in inflation. Social unrest mounted in the wake of these higher prices and culminated in widespread rebellions and demonstrations, especially in the form of the "smashing" of rice establishments. Meanwhile, supporters of the Meiji Emperor leveraged the disruption that these widespread rebellious demonstrations were causing to further consolidate power by overthrowing the last Tokugawa shogun, Yoshinobu, in 1867. After about 263 years, the Pax Tokugawa came to an end.

1869–1943

Main articles: Tokyo City and Tokyo Prefecture

In 1869, the 17-year-old Emperor Meiji moved to Edo, and in accordance the city was renamed Tokyo (meaning Eastern Capital). Tokyo was already the nation's political and cultural center, and the emperor's residence made it a de facto imperial capital as well, with the former Edo Castle becoming the Imperial Palace. The city of Tokyo was officially established on May 1, 1889.

Central Tokyo, like Osaka, has been designed since about 1900 to be centered on major railway stations in a high-density fashion, so suburban railways were built relatively cheaply at street level and with their own right-of-way. This differs from many cities in the United States that are low-density and automobile-centric. Though expressways have been built in Tokyo, the basic design has not changed.

Tokyo went on to suffer two major catastrophes in the 20th century: the 1923 Great Kantō earthquake, which left 140,000 dead or missing; and World War II.

1943–present

In 1943, the city of Tokyo merged with the "Metropolitan Prefecture" of Tokyo. Since then, the Tokyo metropolitan government served as both the prefecture government for Tokyo, as well as administering the Special wards of Tokyo, for what had previously been Tokyo City. World War II wrought widespread destruction of most of the city due to the persistent Allied air raids on Japan and the use of incendiary bombs. The bombing of Tokyo in 1944 and 1945 is estimated to have killed between 75,000 and 200,000 civilians and left more than half of the city destroyed. The deadliest night of the war came on March 9–10, 1945, as nearly 700,000 incendiary bombs rained on the eastern half of the city, mainly in heavily residential wards. Two-fifths of the city were completely burned, more than 276,000 buildings were demolished, 100,000 civilians were killed, and 110,000 more were injured. Between 1940 and 1945, the population of Japan's capital city dwindled from 6,700,000 to less than 2,800,000, with the majority of those who lost their lives living in "ramshackle, makeshift huts".

After the war, Tokyo was completely rebuilt, and was showcased to the world during the 1964 Summer Olympics. The 1970s brought new high-rise developments such as Sunshine 60, a new and controversial airport at Narita in 1978 (some distance outside city limits), and a population increase to about 11 million (in the metropolitan area).

Tokyo's subway and commuter rail network became one of the busiest in the world as more and more people moved to the area. In the 1980s, real estate prices skyrocketed during a real estate and debt bubble. The bubble burst in the early 1990s, and many companies, banks, and individuals were caught with mortgage backed debts while real estate was shrinking in value. A major recession followed, making the 1990s Japan's "Lost Decade" from which it is now slowly recovering.

Tokyo still sees new urban developments on large lots of less profitable land. Recent projects include Ebisu Garden Place, Tennozu Isle, Shiodome, Roppongi Hills, Shinagawa (now also a Shinkansen station), and the Marunouchi side of Tokyo Station. Buildings of significance are demolished for more up-to-date shopping facilities such as Omotesando Hills.

Land reclamation projects in Tokyo have also been going on for centuries. The most prominent is the Odaiba area, now a major shopping and entertainment center. Various plans have been proposed for transferring national government functions from Tokyo to secondary capitals in other regions of Japan, in order to slow down rapid development in Tokyo and revitalize economically lagging areas of the country. These plans have been controversial within Japan and have yet to be realized.

The 2011 Tōhoku earthquake and tsunami that devastated much of the northeastern coast of Honshu was felt in Tokyo. However, due to Tokyo's earthquake-resistant infrastructure, damage in Tokyo was very minor compared to areas directly hit by the tsunami, although activity in the city was largely halted. The subsequent nuclear crisis caused by the tsunami has also largely left Tokyo unaffected, despite occasional spikes in radiation levels.

On September 7, 2013, the IOC selected Tokyo to host the 2020 Summer Olympics. Tokyo will be the first Asian city to host the Olympic Games twice.

Geography and administrative divisions

Tokyo Metropolitan Government Building

The mainland portion of Tokyo lies northwest of Tokyo Bay and measures about 90 km (56 mi) east to west and 25 km (16 mi) north to south. The average elevation in Tokyo is 40 m (131 ft). Chiba Prefecture borders it to the east, Yamanashi to the west, Kanagawa to the south, and Saitama to the north. Mainland Tokyo is further subdivided into the special wards (occupying the eastern half) and the Tama area (多摩地域) stretching westwards.

Also within the administrative boundaries of Tokyo Metropolis are two island chains in the Pacific Ocean directly south: the Izu Islands, and the Ogasawara Islands, which stretch more than 1,000 km (620 mi) away from the mainland. Because of these islands and the mountainous regions to the west, Tokyo's overall population density figures far underrepresent the real figures for the urban and suburban regions of Tokyo.

Under Japanese law, Tokyo is designated as a to (都), translated as metropolis. Its administrative structure is similar to that of Japan's other prefectures. The 23 special wards (特別区 -ku), which until 1943 constituted the city of Tokyo, are now separate, self-governing municipalities, each having a mayor, a council, and the status of a city.

In addition to these 23 special wards, Tokyo also includes 26 more cities (市 -shi), five towns (町 -chō or machi), and eight villages (村 -son or -mura), each of which has a local government. The Tokyo Metropolitan Government, which administers the whole metropolis, is headed by a publicly elected governor and metropolitan assembly. Its headquarters are located in Shinjuku Ward.

Special wards

A map of Tokyo's 23 Special wards

The special wards (特別区, tokubetsu-ku) of Tokyo comprise the area formerly incorporated as Tokyo City. On July 1, 1943, Tokyo City was merged with Tokyo Prefecture (東京府, Tōkyō-fu) forming the current "metropolitan prefecture". As a result, unlike other city wards in Japan, these wards are not conterminous with a larger incorporated city. While falling under the jurisdiction of Tokyo Metropolitan Government, each ward is also a borough with its own elected leader and council, like other cities of Japan. The special wards use the word "city" in their official English name (e.g. Chiyoda City).

The wards differ from other cities in having a unique administrative relationship with the prefectural government. Certain municipal functions, such as waterworks, sewerage, and fire-fighting, are handled by the Tokyo Metropolitan Government. To pay for the added administrative costs, the prefecture collects municipal taxes, which would usually be levied by the city.

The special wards of Tokyo are:

• Adachi
• Arakawa
• Bunkyo
• Chiyoda

• Chūō
• Edogawa
• Itabashi
• Katsushika

• Kita
• Kōtō
• Meguro
• Minato

• Nakano
• Nerima
• Ōta
• Setagaya

• Shibuya
• Shinagawa
• Shinjuku
• Suginami

• Sumida
• Taitō
• Toshima

The "three central wards" of Tokyo – Chiyoda, Chūō and Minato – are the business core of the city, with a daytime population more than seven times higher than their nighttime population. Chiyoda Ward is unique in that it is in the very heart of the former Tokyo City, yet is one of the least populated wards. It is occupied by many major Japanese companies, and is also the seat of the national government, and the Japanese emperor. It is often called the "political center" of the country. Akihabara, known for being an otaku cultural center and a shopping district for computer goods, is also located in Chiyoda.

Tama Area (Western Tokyo)

A map of cities in western part of Tokyo. They border on the three westernmost special wards in the map above

To the west of the special wards, Tokyo Metropolis consists of cities, towns and villages that enjoy the same legal status as those elsewhere in Japan.

While serving as "bed towns" for those working in central Tokyo, some of them also have a local commercial and industrial base. Collectively, these are often known as the Tama Area or Western Tokyo.

Cities

Twenty-six cities lie within the western part of Tokyo:

• Akiruno
• Akishima
• Chōfu
• Fuchū
• Fussa

• Hachiōji
• Hamura
• Higashikurume
• Higashimurayama
• Higashiyamato

• Hino
• Inagi
• Kiyose
• Kodaira
• Koganei

• Kokubunji
• Komae
• Kunitachi
• Machida
• Mitaka

• Musashimurayama
• Musashino
• Nishitōkyō
• Ōme
• Tachikawa
• Tama

The Tokyo Metropolitan Government has designated Hachiōji, Tachikawa, Machida, Ōme and Tama New Town as regional centers of the Tama area, as part of its plans to disperse urban functions away from central Tokyo.

Nishi-Tama District

Map of Nishi-Tama District in green

The far west is occupied by the district (gun) of Nishi-Tama. Much of this area is mountainous and unsuitable for urbanization. The highest mountain in Tokyo, Mount Kumotori, is 2,017 m (6,617 ft) high; other mountains in Tokyo include Takasu (1,737 m (5,699 ft)), Odake (1,266 m (4,154 ft)), and Mitake (929 m (3,048 ft)). Lake Okutama, on the Tama River near Yamanashi Prefecture, is Tokyo's largest lake. The district is composed of three towns (Hinode, Mizuho and Okutama) and one village (Hinohara).

Islands

Map of the Ogasawara Islands in black labels

Tokyo has numerous outlying islands, which extend as far as 1,850 km (1,150 mi) from central Tokyo. Because of the islands' distance from the administrative headquarters of the metropolitan government in Shinjuku, local offices administer them.

The Izu Islands are a group of volcanic islands and form part of the Fuji-Hakone-Izu National Park. The islands in order from closest to Tokyo are Izu Ōshima, Toshima, Nii-jima, Shikine-jima, Kōzu-shima, Miyake-jima, Mikurajima, Hachijō-jima, and Aogashima. The Izu Islands are grouped into three subprefectures. Izu Ōshima and Hachijojima are towns. The remaining islands are six villages, with Niijima and Shikinejima forming one village.

The Ogasawara Islands include, from north to south, Chichi-jima, Nishinoshima, Haha-jima, Kita Iwo Jima, Iwo Jima, and Minami Iwo Jima. Ogasawara also administers two tiny outlying islands: Minami Torishima, the easternmost point in Japan and at 1,850 km (1,150 mi) the most distant island from central Tokyo, and Okinotorishima, the southernmost point in Japan. Japan's claim on an exclusive economic zone (EEZ) surrounding Okinotorishima is contested by China and South Korea as they regard Okinotorishima as uninhabitable rocks which have no EEZ. The Iwo chain and the outlying islands have no permanent population, but host Japanese Self-Defense Forces personnel. Local populations are only found on Chichi-jima and Haha-jima. The islands form both Ogasawara Subprefecture and the village of Ogasawara, Tokyo.

National parks

Fuji-Hakone-Izu National Park

Ogasawara National Park, a UNESCO World Natural Heritage site

As of March 31, 2008, 36% of the total land area of the prefecture was designated as Natural Parks (second only to Shiga Prefecture), namely the Chichibu Tama Kai, Fuji-Hakone-Izu, and Ogasawara National Parks (the last a UNESCO World Heritage Site); Meiji no Mori Takao Quasi-National Park; and Akikawa Kyūryō, Hamura Kusabana Kyūryō, Sayama, Takao Jinba, Takiyama, and Tama Kyūryō Prefectural Natural Parks.

Ueno Park is well known for its museums: Tokyo National Museum, National Museum of Nature and Science, Shitamachi Museum and National Museum for Western Art, among others. There are also art works and statues at several places in the park. There is also a zoo in the park, and the park is a popular destination to view cherry blossoms.

Seismicity

Tokyo was hit by powerful earthquakes in 1703, 1782, 1812, 1855, 1923, and 2011. The 1923 earthquake, with an estimated magnitude of 8.3, killed 142,000 people. Tokyo is near the boundary of three plates.

Climate

The former city of Tokyo and the majority of mainland Tokyo lie in the humid subtropical climate zone (Köppen climate classification Cfa), with hot humid summers and generally mild winters with cool spells. The region, like much of Japan, experiences a one-month seasonal lag, with the warmest month being August, which averages 26.4 °C (79.5 °F), and the coolest month being January, averaging 5.2 °C (41.4 °F). The record low temperature is −9.2 °C (15.4 °F), and the record high is 39.5 °C (103.1 °F), though there was once an unofficial reading of 42.7 °C (108.9 °F) at the Primary School Station. Annual rainfall averages nearly 1,530 millimetres (60.2 in), with a wetter summer and a drier winter. Snowfall is sporadic, but does occur almost annually. Tokyo also often sees typhoons every year, though few are strong. The last one to hit was Fitow in 2007, while the most rainy month since records began in 1876 has been October 2004 with 780 millimetres (30 in) of rain, including 270.5 millimetres (10.6 in) on the ninth of that month.

Tokyo's easternmost territory, the island of Minamitorishima (Marcus Island) in Ogasawara village, is in the tropical savanna climate zone (Köppen classification Aw). Tokyo's Izu and Ogasawara islands are affected by an average of 5.4 typhoons a year, compared to 3.1 in mainland Kantō.

Cityscape

Architecture in Tokyo has largely been shaped by Tokyo's history. Twice in recent history has the metropolis been left in ruins: first in the 1923 Great Kantō earthquake and later after extensive firebombing in World War II. Because of this, Tokyo's urban landscape consists mainly of modern and contemporary architecture, and older buildings are scarce. Tokyo features many internationally famous forms of modern architecture including Tokyo International Forum, Asahi Beer Hall, Mode Gakuen Cocoon Tower, NTT Docomo Yoyogi Building and Rainbow Bridge. Tokyo also features two distinctive towers: Tokyo Tower and the new Tokyo Skytree which is the tallest tower in Japan and the second tallest structure in the world after the Burj Khalifa in Dubai.

Tokyo also contains numerous parks and gardens. There are four national parks in Tokyo Prefecture, including the Fuji-Hakone-Izu National Park, which includes all of the Izu Islands.

Environment

Tokyo has enacted a measure to cut greenhouse gases. Governor Shintaro Ishihara created Japan's first emissions cap system, aiming to reduce greenhouse gas emission by a total of 25% by 2020 from the 2000 level. Tokyo is an example of an urban heat island, and the phenomenon is especially serious in its special wards. According to the Tokyo Metropolitan Government, the annual mean temperature has increased by about 3 °C (5.4 °F) over the past 100 years. Tokyo has been cited as a "convincing example of the relationship between urban growth and climate."

In 2006, Tokyo enacted the "10 Year Project for Green Tokyo" to be realised by 2016. It set a goal of increasing roadside trees in Tokyo to 1 million (from 480,000), and adding 1,000 ha of green space 88 of which will be a new park named "Umi no Mori" (sea forest) which will be on a reclaimed island in Tokyo Bay which used to be a landfill. From 2007 to 2010 436 ha of the planned 1,000 ha of green space was created and 220,000 trees were planted bringing the total to 700,000. By 2014 road side trees in Tokyo will increase to 950,000 and a further 300 ha of green space will be added.

Demographics

As of October 2012, the official intercensal estimate showed 13.506 million people in Tokyo with 9.214 million living within Tokyo's 23 wards. During the daytime, the population swells by over 2.5 million as workers and students commute from adjacent areas. This effect is even more pronounced in the three central wards of Chiyoda, Chūō, and Minato, whose collective population as of the 2005 National Census was 326,000 at night, but 2.4 million during the day.

In 1889, the Ministry of Home Affairs recorded 1,375,937 people in Tokyo City and a total of 1,694,292 people in Tokyo-fu. In the same year, a total of 779 foreign nationals were recorded as residing in Tokyo. The most common nationality was British (209 residents), followed by United States nationals (182) and nationals of the Qing dynasty (137).

Economy

Tokyo has the largest metropolitan economy in the world. According to a study conducted by PricewaterhouseCoopers, the Tokyo urban area (35 million people) had a total GDP of US$1.9 trillion in 2012 (at purchasing power parity), which topped that list. 51 of the companies listed on the Fortune Global 500 are based in Tokyo, almost twice that of the second-placed city (Paris).

Tokyo is a major international finance center, houses the headquarters of several of the world's largest investment banks and insurance companies, and serves as a hub for Japan's transportation, publishing, electronics and broadcasting industries. During the centralised growth of Japan's economy following World War II, many large firms moved their headquarters from cities such as Osaka (the historical commercial capital) to Tokyo, in an attempt to take advantage of better access to the government. This trend has begun to slow due to ongoing population growth in Tokyo and the high cost of living there.

Tokyo was rated by the Economist Intelligence Unit as the most expensive (highest cost-of-living) city in the world for 14 years in a row ending in 2006.

Tokyo has been described as one of the three "command centers" for the world economy, along with New York City and London. The Tokyo Stock Exchange is Japan's largest stock exchange, and third largest in the world by market capitalization and fourth largest by share turnover. In 1990 at the end of the Japanese asset price bubble, it accounted for more than 60% of the world stock market value. Tokyo had 8,460 ha (20,900 acres) of agricultural land as of 2003, according to the Ministry of Agriculture, Forestry and Fisheries, placing it last among the nation's prefectures. The farmland is concentrated in Western Tokyo. Perishables such as vegetables, fruits, and flowers can be conveniently shipped to the markets in the eastern part of the prefecture. Komatsuna and spinach are the most important vegetables; as of 2000, Tokyo supplied 32.5% of the komatsuna sold at its central produce market.

With 36% of its area covered by forest, Tokyo has extensive growths of cryptomeria and Japanese cypress, especially in the mountainous western communities of Akiruno, Ōme, Okutama, Hachiōji, Hinode, and Hinohara. Decreases in the price of timber, increases in the cost of production, and advancing old age among the forestry population have resulted in a decline in Tokyo's output. In addition, pollen, especially from cryptomeria, is a major allergen for the nearby population centers. Tokyo Bay was once a major source of fish. Currently, most of Tokyo's fish production comes from the outer islands, such as Izu Ōshima and Hachijōjima. Skipjack tuna, nori, and aji are among the ocean products.

Tourism in Tokyo is also a contributor to the economy. In 2006, 4.81 million foreigners and 420 million Japanese visits to Tokyo were made; the economic value of these visits totaled 9.4 trillion yen according to the government of Tokyo. Many tourists visit the various downtowns, stores, and entertainment districts throughout the neighbourhoods of the special wards of Tokyo; particularly school children on class trips, a visit to Tokyo Tower is de rigueur. Cultural offerings include both omnipresent Japanese pop culture and associated districts such as Shibuya and Harajuku, subcultural attractions such as Studio Ghibli anime center, as well as museums like the Tokyo National Museum, which houses 37% of the country's artwork national treasures (87/233).

The Tsukiji Fish Market in central Tokyo is the biggest wholesale fish and seafood market in the world and also one of the largest wholesale food markets of any kind. The Tsukiji market holds strong to the traditions of its predecessor, the Nihombashi fish market, and serves some 50,000 buyers and sellers every day. Retailers, whole-sellers, auctioneers, and public citizens alike frequent the market, creating a unique microcosm of organized chaos that still continues to fuel the city and its food supply after over four centuries.

Transportation

Map of Tokyo Subway system

Tokyo, as the center of the Greater Tokyo Area, is Japan's largest domestic and international hub for rail, ground, and air transportation. Public transportation within Tokyo is dominated by an extensive network of clean and efficient trains and subways run by a variety of operators, with buses, monorails and trams playing a secondary feeder role.

Within Ōta, one of the 23 special wards, Haneda Airport offers domestic and international flights. Outside Tokyo, Narita International Airport, in Chiba Prefecture, is the major gateway for international travelers to Japan. Japan's flag carrier Japan Airlines, as well as All Nippon Airways, Delta Air Lines, and United Airlines all have a hub at this airport.

Various islands governed by Tokyo have their own airports. Hachijō-jima (Hachijojima Airport), Miyakejima (Miyakejima Airport), and Izu Ōshima (Oshima Airport) have services to Tokyo International and other airports.

Rail is the primary mode of transportation in Tokyo, which has the most extensive urban railway network in the world and an equally extensive network of surface lines. JR East operates Tokyo's largest railway network, including the Yamanote Line loop that circles the center of downtown Tokyo. Two different organisations operate the subway network: the private Tokyo Metro and the governmental Tokyo Metropolitan Bureau of Transportation. The metropolitan government and private carriers operate bus routes and one tram route. Local, regional, and national services are available, with major terminals at the giant railroad stations, including Tokyo, Shinagawa, and Shinjuku.

Expressways link the capital to other points in the Greater Tokyo area, the Kantō region, and the islands of Kyushu and Shikoku. In order to build them quickly before the 1964 Summer Olympics, most were constructed above existing roads. Other transportation includes taxis operating in the special wards and the cities and towns. Also long-distance ferries serve the islands of Tokyo and carry passengers and cargo to domestic and foreign ports.

The Sanja Festival in Asakusa

Many different festivals occur throughout Tokyo. Major events include the Sannō at Hie Shrine, the Sanja at Asakusa Shrine, and the biennial Kanda Festivals. The last features a parade with elaborately decorated floats and thousands of people. Annually on the last Saturday of July, an enormous fireworks display over the Sumida River attracts over a million viewers. Once cherry blossoms bloom in spring, many residents gather in Ueno Park, Inokashira Park, and the Shinjuku Gyoen National Garden for picnics under the blossoms.

Harajuku, a neighbourhood in Shibuya, is known internationally for its youth style, fashion and cosplay.

Cuisine in Tokyo is internationally acclaimed. In November 2007, Michelin released their first guide for fine dining in Tokyo, awarding 191 stars in total, or about twice as many as Tokyo's nearest competitor, Paris. Eight establishments were awarded the maximum of three stars (Paris has 10), 25 received two stars, and 117 earned one star. Of the eight top-rated restaurants, three offer traditional Japanese fine dining, two are sushi houses and three serve French cuisine.

With a number of world-class sports venues, Tokyo often hosts national and international sporting events such as tennis tournaments, swim meets, marathons, rugby union and sevens rugby games, football, American football exhibition games, judo, and karate. Tokyo Metropolitan Gymnasium, in Sendagaya, Shibuya, is a large sports complex that includes swimming pools, training rooms, and a large indoor arena. According to Around the Rings, the gymnasium has played host to the October 2011 artistic gymnastics world championships, despite the International Gymnastics Federation's initial doubt in Tokyo's ability to host the championships following the March 11 tsunami. Tokyo was selected to host the 2020 Summer Olympics on September 7, 2013.

In popular culture

Fuji TV headquarters

As the largest population center in Japan and the site of the country's largest broadcasters and studios, Tokyo is frequently the setting for many Japanese movies, television shows, animated series (anime), web comics, and comic books (manga). In the kaiju (monster movie) genre, landmarks of Tokyo are routinely destroyed by giant monsters such as Godzilla and Gamera.

Some Hollywood directors have turned to Tokyo as a backdrop for movies set in Japan. Well-known postwar examples include Tokyo Joe, My Geisha, Tokyo Story and the James Bond film You Only Live Twice; well-known recent examples include Kill Bill, The Fast and the Furious: Tokyo Drift, Lost in Translation, Babel, Inception, and the Paramount and Michael Bay's upcoming film Transformers 5.
