Tokyo city in Japan

Tokyo, officially Tokyo Metropolis is one of the 47 prefectures of Japan. It is located on the eastern 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 and the city of Tokyo. 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 the Imperial Palace, and the home of the Family. The Tokyo Metropolitan government administers the twenty-three special wards of Tokyo, each governed as a city, that 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. 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 and named the third Most Liveable City and the World’s Most Livable Megalopolis by the magazine Monocle.
