Exhibitions are on semi-annual rotation: The current show is a mix of collages, furniture, and oversized polka-dot sculptures created over four decades and runs through January 31; the next exhibition has not yet been announced. As with most Kusama exhibits, you'll need to buy the 1,000 yen ($9) tickets online a month in advance for one of the four 90-minute slots per day."
