Expo '70

The Japan World Exposition, Osaka, 1970 (日本万国博覧会, Nihon Bankoku Hakuran-kai) or Expo '70 was a world's fair held in Suita, Osaka Prefecture, Japan, between 15 March and 13 September 1970. Its theme was "Progress and Harmony for Mankind." In Japanese, Expo '70 is often referred to as Ōsaka Banpaku (大阪万博). It was the first world's fair held in Japan as well as in Asia. The Expo was designed by Japanese architect Kenzō Tange, assisted by 12 other Japanese architects. Bridging the site along a north–south axis was the Symbol Zone. Planned on three levels, it was primarily a social space with a unifying space frame roof. The Expo attracted international attention for the extent to which unusual artworks and designs by Japanese avant-garde artists were incorporated into the overall plan and individual national and corporate pavilions. The most famous of these artworks is artist Tarō Okamoto's iconic Tower of the Sun, which remains on the site.
