Art from from both Japan and overseas since 1945 is the focus of this museum, and with three floors devoted to temporary exhibits and two floors showcasing its own collection, it's the largest modern and contemporary art museum in Japan. Changing exhibits have ranged from contemporary Spanish and Latin American art to a retrospective on Jasper Johns, while the museum's own collection covers everything from anti-artistic trends and pop art in the 1960s to cutting-edge contemporary works, with about 100 pieces on display on a rotating basis. Depending on your interest, you'll spend anywhere from 1 to 2 hours here, and since it's out of the way, you might want to combine it with a trip to the Fukagawa Edo Museum, which you'll pass on the way.
