Famous architect Kisho Kurokawa designed this groovy building for a world’s fair in Osaka called EXPO ’70–the first to be held in Japan. Kurokawa took a great interest in philosophy and idealized, himself, that every culture has two traditions: the visible and the invisible. He focused the majority of his work on Japan’s “invisible” traditions, including the impermanence of structures in the country due to destruction by weather and war. Designing a building for a world’s fair is the height of impermanence since most of those built for these events did not last. The modular design of this particular work speaks to the idea of impermanence since modular structures are meant to recall ideas of an endlessly possible cycle of deconstruction and rebuilding.
