21_21 Design Sight is a museum designed by one of Japan's most famous contemporary architects, Tadao Ando. The naturally lit space, of which some 80 percent is underground, is home to Japan's first design museum. The simple lines of the building's steel-and-concrete roof are typically Japanese in their emphasis on modesty. The museum is nestled in a green park, which softens the sharp exterior. Temporary exhibitions typically focus on the role design plays in daily life and how we interact with it. The museum is near the Tokyo Midtown complex in Roppongi, a short walk from Nogizaka Station.
