Tokyo

Tokyo, officially Tokyo Metropolis is one of the 47 prefectures of Japan and is located on the eastern side of the main island Honshū. Tokyo's government also administers the twenty-three special wards of Tokyo, each governed as a city, that cover the area that was once the city of Tokyo in the eastern part of the prefecture. The population of the special wards is over 8 million people, with the total population of the prefecture exceeding 12 million. The prefecture is the center of the Greater Tokyo Area, the world's most populous metropolitan area with 35 to 39 million people (depending on definition) and the world's largest metropolitan economy with a GDP of US$1.479 trillion at purchasing power parity in 2008. Tokyo was described by Saskia Sassen as one of the three "command centers" for the world economy, along with London and New York City.[4] This city is considered an alpha+ world city, listed by the GaWC's 2008 inventory[5] and ranked fourth among global cities by Foreign Policy's 2008 Global Cities Index. In 2009 Tokyo was named the world's most expensive city for expatriate employees, according to the Mercer and Economist Intelligence Unit cost-of-living surveys [6] and named the third Most Liveable City and the Worlds Most Livable Megalopolis by the magazine Monocle.[7] Tokyo is the seat of the Japanese government and the Imperial Palace, and the home of the Japanese Imperial Family.
