During the 1950s a group of Japanese architects formed the Metabolism movement, which sought to revolutionize the way buildings are designed in relation to expanding cities.

This exhibition provides a 21st-century perspective on the movement, with a focus on half-size models from architects such as Ryue Nishizawa and architecture duo Atelier Bow-Wow. "Tokyo Metabolizing," the 2010 Venice Biennale Japanese pavilion exhibit, will also be on display.

The exhibits not only present Tokyo's individual architectural style, but incorporate architectural innovations designed to foster relationships and communities and help break down the isolated lifestyles that many people now live in the metropolis; till Oct. 2.
