An auditorium that looks like it was designed by traditional Japanese craftsmen. I Land Hall hosts a number of concerts, fashion events, and other gatherings in the Shinjuku area. Its form is completely circular, like a massive architectural barrel. About a quarter of the way up the exterior are two rows of windows, and there are other bands farther up. The building's simple design makes maximum use of what little space is available to it. The round shape on a triangular plot allows it to serve its purpose while also creating public spaces for crowds to gather and disperse before and after events.
