The summer just gets hotter and hotter for visual-art fans in Japan. Following on the heels of Art Fair Tokyo, which attracted 43,000 visitors to Tokyo International Forum last weekend, the nation's largest art event of all, the once-every-three-years Yokohama Triennale, opens Saturday.

Yoko Ono, Damien Hirst, Tadanori Yokoo and Hiroshi Sugimoto lead a star-studded, international lineup of 77 artists and artist units at the event, which will take place at multiple venues throughout Yokohama from Aug. 6 to Nov. 6.

The theme of this year's triennale was chosen prior to the Great East Japan Earthquake of March 11, but it has taken on even greater significance since then: "Our Magic Hour: How Much of the World Can We Know?"
