Tokyo, Japan

Tokyo  is one of the 47 prefectures of Japan. It is located in theKantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. 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 the capital of Japan, the center of the Greater Tokyo Area, and the largest metropolitan area of Japan. It is the seat of the Japanese government and theImperial Palace, and the home of the Japanese Imperial Family.

The Tokyo Metropolitan government administers the twenty-three special wards of Tokyo (each governed as a city), which cover the area that was the city of Tokyo, as well as 39 municipalities in the western part of the prefecture and the two outlying island chains. The population of the special wards is over 8 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 35 million people and the world's largest metropolitan economy with a GDP of US$1.479 trillion at purchasing power parity in 2008, ahead of New York City, which ranks second on the list. The city hosts 47 of the Fortune Global 500 companies.

Tokyo has been described as one of the three "command centers" for the world economy, along with New York City and London. This city is considered an alpha+ world city, listed by the GaWC's 2008 inventory and ranked third among global cities by Foreign Policy's 2010 Global Cities Index. In 2010 Tokyo was named the second most expensive city for expatriate employees, according to the Mercer and Economist Intelligence Unit cost-of-living surveys, and named the fourth Most Liveable City and the World’s Most Livable Megalopolis by the magazine Monocle. 

The Michelin Guide has awarded Tokyo by far the most Michelin stars of any city in the world. Tokyo hosted the 1964 Summer Olympics and is currently bidding to host the 2020 Summer Olympics.
