Itsuko Hasegawa designed the Fruit Museum in the Yamanashi Prefecture near Mount Fuji in Japan. It was completed in 1997. The three shell-shaped buildings symbolize the "fruits" of spiritual sensuality, intelligence and lust.

As an expression of contextual ecology, white light shines through screened structure in a paradisaical greenhouse. Arup did the engineering for this project, quite a feat of curved exoskeleton structure.

In a general sense, the buildings are trees producing fruits of creativity in the visitors who themselves will spread a sensitivity to our frail environment, and hopefully produce green buildings themselves.
