This architectural marvel designed by Rafael Viñoly houses a convention and arts centre, with eight auditoriums and a spacious courtyard in which concerts and events are held. The eastern wing looks like a glass ship plying the urban waters; you can access the catwalks from the 7th floor (take the lift).
Also visit for the twice-monthly Ōedo Antique Market, and the food trucks serving bargain meals and drinks to local office workers at lunch Monday to Friday.
