Greater Tokyo Area

The Greater Tokyo Area is the most populous metropolitan area in the world, consisting of the Kantō region of Japan, including the Tokyo Metropolis, as well as the prefecture of Yamanashi. In Japanese, it is referred to by various terms, the most common of which being National Capital Region (首都圏, Shuto-ken).

A 2014 estimate puts the population at 37,832,892 with more people than the countries of Canada or Iraq. It covers an area of approximately 13,500 km² (5,200 mi²), giving it a population density of 2,642 person/km², which is more than twice the population density of Bangladesh. It is the second largest single metropolitan area in the world in terms of built-up or urban function landmass at 8,547 km² (3,300 mi²), behind only New York City at 11,642 km² (4,495 mi²).

The area has the largest metropolitan economy in the world, with a total GDP (nominal) of approximately US$1.9 trillion (¥165 trillion) in 2008. According to research published by PricewaterhouseCoopers, the agglomeration of Tokyo had a total GDP of US$1.479 trillion in 2008 (at purchasing power parity), ranking again as the largest urban agglomeration GDP in the world.

Metropolitan area

A metropolitan area, sometimes referred to as a metropolitan area, metro area or just metro, is a region consisting of a densely populated urban core and its less-populated surrounding territories, sharing industry, infrastructure, and housing. A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, cities, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include one or more urban areas, as well as satellite cities, towns and intervening rural areas that are socio-economically tied to the urban core, typically measured by commuting patterns.

For urban centres outside metropolitan areas, that generate a similar attraction at smaller scale for their region, the concept of the regiopolis and respectively regiopolitan area or regio was introduced by German professors in 2006.

Tokyo

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 largest 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 City

Tokyo City (東京市, Tōkyō-shi) was a municipality in Japan and part of Tokyo-fu which existed from 1 May 1889 until its merger with its prefecture on 1 July 1943. The historical boundaries of Tokyo City are now occupied by the 23 Special Wards of Tokyo. The new merged government became what is now Tokyo, also known as the Tokyo Metropolis, or, ambiguously, Tokyo Prefecture.

History

In 1868, the medieval city of Edo, seat of the Tokugawa government, was renamed Tokyo, and the offices of Tokyo Prefecture (-fu) were opened. The extent of Tokyo Prefecture was initially limited to the former Edo city, but rapidly augmented to be comparable with the present Tokyo Metropolis. In 1878, the Meiji government's reorganization of local governments subdivided prefectures into counties or districts (gun, further subdivided into towns and villages, later reorganized similar to Prussian districts) and districts or wards (ku) which were in ordinary prefectures cities as a whole, e.g. today's Hiroshima City (-shi) was then Hiroshima-ku; the three major cities of Tokyo, Osaka and Kyoto were each subdivided into several such wards. In Tokyo Prefecture, this created 15 wards (listed below) and six counties/districts.

Summer Olympic Games

The Summer Olympic Games or the Games of the Olympiad (French: Jeux olympiques d'été), first held in 1896, are an international multi-sport event, occurring every four years, organized by the International Olympic Committee. Medals are awarded in each event, with gold medals for first place, silver for second and bronze for third, a tradition that started in 1904. The Winter Olympic Games were also created due to the success of the Summer Olympics.

The Olympics have increased from a 42-event competition with fewer than 250 male competitors from 14 nations to a 300-event sporting celebration with over 10,000 competitors from 205 nations. Organizers for the 2008 Summer Olympics in Beijing expected approximately 10,500 competitors to take part in the 302 events on the program for the games.

Eighteen countries have hosted the Summer Olympics, with Great Britain 2012 being the most recent. The United States has hosted four Summer Olympics (1904, 1932, 1984, and 1996), more than any other nation, and Great Britain has hosted three Summer Olympics (1908, 1948, and 2012), all in London. Three cities have hosted two Summer Olympics: Los Angeles (1932 and 1984), Paris (1900 and 1924), and Athens (1896 and 2004).
