Tokyo

Tokyo (東京 ,Tōkyō?), officially Tokyo Metropolis (東京都 ,Tōkyō-to?),[2] is one of the 47 prefectures of Japan and located on the eastern side of the main island Honshū. The twenty-three special wards of Tokyo, each governed as a city, cover the area that was once the city of Tokyo in the eastern part of the prefecture, and total over 8 million people. The population of the prefecture exceeds 12 million. The prefecture is the center of the Greater Tokyo Area, the world's most populous metropolitan area with 35 million people and the world's largest metropolitan economy with a GDP of US$1.191 trillion at purchasing power parity in 2005.

Tokyo is the seat of the Japanese government and the Imperial Palace, and the home of the Japanese Imperial Family.
Tokyo was originally a small fishing village named Edo. In 1457, Ōta Dōkan built Edo Castle. In 1590, Tokugawa Ieyasu made Edo his base and 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.[6] It became the de facto capital of Japan[7] even while the emperor lived in Kyoto, the imperial capital. After about 263 years, the shogunate was overthrown under the banner of restoring imperial rule. In 1869, the 17-year-old Emperor Meiji moved to Edo. Tokyo was already the nation's political and cultural center,[8] 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 established, and continued to be the capital until it was abolished as a municipality in 1943 and merged with the "Metropolitan Prefecture" of Tokyo.

Central Tokyo, like Osaka, has been designed since about the turn of the century (1900) to be centered around major train stations in a high-density fashion[citation needed], so suburban railways were built relatively cheaply at street level and with their own right-of-way. This differs from cities in the United States, such as Los Angeles, 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, but it recovered from both. One was the 1923 Great Kantō earthquake, and the other was World War II. The bombing of Tokyo in 1945, with 75,000 to 200,000 killed and half of the city destroyed, were almost as devastating as the atomic bombs of Hiroshima and Nagasaki combined.[9] After the war, Tokyo was completely rebuilt, and showcased to the world during the 1964 Summer Olympics. The 1970s brought new high-rise developments such as Sunshine 60, a new and controversial[10] 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,[11] 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"[12] from which it is 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[13] 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[14] within Japan and have yet to be realized.
The mainland portion of Tokyo lies northwest of Tokyo Bay and measures about 90 km east to west and 25 km north to south. 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 away from mainland Japan. Because of these islands and mountainous regions to the west, Tokyo's overall population density figures far underrepresent the real figures for urban and suburban regions of Tokyo.

Under Japanese law, Tokyo is designated as a to (都), translated as metropolis.[15] Its administrative structure is similar to that of Japan's other prefectures. Within Tokyo lie dozens of smaller entities, most of them conventionally[citation needed] referred to as cities. It includes twenty-three special wards (特別区 -ku) which until 1943 comprised the city of Tokyo but are now separate, self-governing municipalities, each with a mayor and a council, and having the status of a city. In addition to these 23 municipalities, Tokyo also encompasses 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 is headed by a publicly elected governor and metropolitan assembly. Its headquarters are in the ward of Shinjuku. They govern all of Tokyo, including lakes, rivers, dams, farms, remote islands, and national parks in addition to its famous neon jungle, skyscrapers and crowded subways.
Tokyo is one of the three world finance "command centres", along with New York City and London. Tokyo has the largest metropolitan economy in the world. According to a study conducted by PricewaterhouseCoopers, the Tokyo urban area (35.2 million people) had a total GDP of US$1.191 trillion in 2005 (at purchasing power parity), ranking again as the largest urban agglomeration GDP in the world.[26] As of 2008, 47 of the companies listed on the Global 500 are based in Tokyo, almost twice that of the second-placed city (Paris).[27]

Tokyo is a major international finance center,[28] 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, and broadcasting industries. During the centralized 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.[29] This analysis is for living a Western corporate executive lifestyle, with items like a detached house and several automobiles.

The Tokyo Stock Exchange is Japan's largest stock exchange, and second 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.[30]

Tokyo had 8,460 ha (20,900 acres) of agricultural land as of 2003,[31] 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. Japanese leaf spinach and spinach are the most important vegetables; as of 2000, Tokyo supplied 32.5% of the Japanese leaf spinach 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 lumber, 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. Presently, 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.
