We all know Japan's urban centers have a penchant for innovative, if kooky, residential designs that bend our notions of what home looks like. Designed by Kubo Tsushima Architects, this public restroom is the logical next step in Japanese architects' steady moves toward a more inventive design solutions for the built environment. Set in the parking lot of a local temple in Nakanojo, Japan, this corrugated metal public toilet has a sinuous form that calls to mind expensive homes and high-end cultural institutions rather than a loo. That's what the designers wanted. "We were asked to create a toilet that could be a symbol of the town, and at the same time, a toilet that is not dismal like ordinary public toilets in Japan," they told Dezeen.
