Yayoi Kusama Museum

Officially opened on October 1, the world's first museum dedicated entirely to bewigged contemporary artist Yayoi Kusama hosts two exhibitions annually, focusing on Kusama's entire repertoire, including her ‘Infinity Net’ paintings, phallic sculptures and, yes, those legendary red polka dots. Note that entry is by time slot (four per day; the museum is open Thursday though Sunday) and that buying tickets in advance is essential - they're not sold on the door. Reserve yours through the museum's website.
