The story
One of its halls seats 5,000. In addition to seven other halls, it includes exhibition space, a lobby, restaurants, shops, and other facilities.
Designed by architect Rafael Viñoly and completed in 1996, it features swooping curves of steel truss and glass; the outside is shaped like an elongated boat.
Standing between Tokyo Station and Yūrakuchō Station, its address is in Marunouchi, Chiyoda, on the site formerly occupied by Tokyo City Hall (before it moved to the Tokyo Metropolitan Government Building in 1991).
On the first floor, facing in the direction of Edo Castle (now the Imperial Palace), is a bronze sculpture of Ōta Dōkan.
