KITTE Marunouchi is a shopping mall that preserves the exterior of the former Tokyo Post Office, located about 100 meters across one street from Tokyo Station. Shops run along a triangular hall from the first to the sixth floor, with souvenir shops and select stores to browse. From the outdoor observation deck on the sixth floor, visitors look down on Tokyo Station and the surrounding high-rise buildings. At night, the view of Tokyo Station includes passing trains.
