Shibuya (渋谷区, Shibuya-ku^?) is one of the 23 special wards of Tokyo, Japan. As of 2008, it has an estimated population of 208,371 and a population density of 13,540 persons per km². The total area is 15.11 km².

The name "Shibuya" is also used to refer to the shopping district which surrounds Shibuya Station, one of Tokyo's busiest railway stations. This area is known as one of the fashion centers of Japan, particularly for young people, and as a major nightlife area.

Following the opening of the Yamanote Line in 1885, Shibuya began to emerge as a railway terminal for southwestern Tokyo and eventually as a major commercial and entertainment center. It was incorporated as a village in Minami-Toshima County (Toyotama County from 1896) in 1889, as a town in 1909, as a ward of Tokyo City in 1932, and as a ward of Tokyo Metropolis in 1943. The present-day special ward was established on March 15, 1947.

One of the most well-known stories concerning Shibuya is the story of Hachikō, a dog who waited on his late master at Shibuya Station every day from 1923 to 1935, eventually becoming a national celebrity for his loyalty. A statue of Hachikō was built adjacent to the station, and the surrounding Hachikō Square is now the most popular meeting point in the area.

Tokyo (東京, Tōkyō^?, "Eastern Capital") [toːkʲoː], English /ˈtoʊki.oʊ/; officially Tokyo Metropolis (東京都, Tōkyō-to^?), is one of the 47 prefectures of Japan. Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the largest metropolitan area of the world. It is the seat of the Japanese government and the Imperial Palace, and the home of the Japanese Imperial Family. Tokyo is in the Kantō 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^?).

The Tokyo Metropolitan government administers the 23 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 urban agglomeration economy with a GDP of US$1.479 trillion at purchasing power parity in 2008, ahead of New York City metropolitan area, which ranks second on the list. The city hosts 47 of the Fortune Global 500 companies, the highest amount of any city.
