Tokyo Metropolitan Government Building


The Tokyo Metropolitan Government Building, also referred to as Tochō for short, houses the headquarters of the Tokyo Metropolitan Government, which governs the special wards, cities, towns and villages that constitutes the whole Tokyo Metropolis.
Located in Shinjuku, the building was designed by architect Kenzo Tange. It consists of a complex of three structures, each taking up a city block. The tallest of the three is Tokyo Metropolitan Main building No.1, a tower 48 stories tall that splits into two sections at the 33rd floor. The building also has three levels below ground. The design of the building was meant to resemble an integrated circuit, while also evoking the look of a Gothic cathedral.
The other two buildings in the complex are the eight-story Tokyo Metropolitan Assembly Building and Tokyo Metropolitan Main Building No.2, which has 37 stories including three below ground.
The two panoramic observation decks, one in each tower on floor 45
, are free of charge to the public and contain gift shops and cafes. The observation decks are open between 9:30 – 23:00, but the two observation decks alternate the dates they are open.
