June 16-Sept. 13

The National Museum of Modern Art, Tokyo, asks the question, "What is an art museum?"

It doesn't matter if you're an art beginner or an expert, this exhibition has been designed to appeal to all. A total of 170 works have been categorized into 36 themes organized in alphabetical order. "A," for example, is for "artist," while "F" is for frame and "O" is for original. In this way artworks can be considered from varied perspectives.

Exhibits include major works, such as Marcel Duchamp's "Fontana," August Rodin's "The Thinker" and Henri Rousseau's "Liberty Inviting Artists to Take Part in the 22nd Exhibition of the Societe des Artistes," as well as other objects and documents that help viewers rethink not only the value of art but where it is displayed.
