This museum boasts one of Japan's largest exhibition spaces, yet it doesn't even have a permanent collection of its own. Rather, it serves as the canvas for Japanese artists' associations, shows organized by its own curators, and joint exhibitions in cooperation with other art institutions and even mass media corporations. As such, its shows are both eclectic and impressive, with past exhibitions including a retrospective of Japanese government-sponsored art exhibitions from the past century; a powerful display of masks, religious idols, and other objects from around the world from Japan's National Museum of Ethnology; a study of California design from 1930 to 1965 with displays of furniture, textiles, fashion, film, architecture, and other objects; and Impressionist and Post-Impressionist art from Washington DC's National Gallery of Art. In other words, you never know what you might see, and in addition to large shows are smaller galleries showing the works of regional and national artists. Many people drop by just to dine in the museum's Brasserie Paul Bocuse Le Musee or browse the museum shop. And of the three museums included in the Art Triangle Roppongi, which includes the nearby Mori Art Museum and Suntory Museum of Art, this is by far the sexiest, with a come-hither undulating facade that would make me want to go there even without knowing what's inside.
