Tokyo Tower (東京タワー, Tōkyō tawā^?) is a communications and observation tower located in Shiba Park, Minato, Tokyo, Japan. At 332.5 metres (1,091 ft), it is the second tallest artificial structure in Japan. The structure is an Eiffel Tower-inspired lattice tower that is painted white and international orange to comply with air safety regulations.

Built in 1958, the tower's main sources of revenue are tourism and antenna leasing. Over 150 million people have visited the tower since its opening. FootTown, a 4-storey building located directly under the tower, houses museums, restaurants and shops. Departing from here, guests can visit two observation decks. The 2-storey Main Observatory is located at 150 metres (490 ft), while the smaller Special Observatory reaches a height of 250 metres (820 ft).

The tower acts as a support structure for an antenna. Originally intended for television broadcasting, radio antennas were installed in 1961 and the tower is now used to broadcast signals for Japanese media outlets such as NHK, TBS and Fuji TV. Japan's planned digital television transition by July 2011 is problematic, however. Tokyo Tower's current height is not high enough to adequately support complete terrestrial digital broadcasting to the area. A taller digital broadcasting tower, known as Tokyo Skytree, was completed in February, 2012.

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.
