Tokyo Metropolitan Government



It is located on a 10-minute walk from the West exit of JR Shinjuku Station. The Tokyo Metropolitan Government started its operation in the unique and impressive building in 1991. Within the premises of approximately 42,940 square meters, the 243-meter-tall Main Building No.1, the Main Building No.2, and the Tokyo Metropolitan Assembly Building are located, and visitors can tour the premises without a prior appointment. The observation deck at a height of 202 meters above ground on the 45th floor of the Main Building No.1 is particularly popular as a sightseeing spot in Tokyo. You can enjoy the view of Mt. Fuji on a fine winter day and a panoramic view of the city glistening with illumination in the evening. Admission is free. In addition, the Tokyo Tourist Information Center and Japanese prefectural tourism promotion booths on the premises are very useful for people traveling not only in Tokyo but also to other areas in Japan. Also, 38 pieces of artwork, including sculptures and reliefs, are displayed in the buildings. Visitors can appreciate works of famous modern art artists in and out of the country as well as the works publicly solicited from the general public or young artists. Dining facilities, cafes, and kiosks are available on the premises, so it is a convenient place to have a break during sightseeing in Tokyo.
