United States Pavilion, Japan World Exposition, Osaka EXPO '70
EXPO ’70 Osaka—Asia’s first-ever Category One World’s Fair—was meant to shine a global spotlight on modern Japan 25 years after World War II. But US EXPO planners were encumbered at home by the growing costs of the Viet Nam war. In 1967, USIA’s Jack Masey organized a competition in which leading American architects and designers were invited to form teams to produce design concepts for an American Pavilion in Osaka. The winning concept—an air-inflatable pavilion—was submitted by the design team of Davis, Brody, Chermayeff, Geismar & de Harak, and structural engineer David Geiger. Twice forced to scrap its plans by Congressional funding cuts, the team’s third and final design was a low-slung air-supported roof of space-age fabric and steel cables above an earthen berm. Constructed in collaboration with Japanese master-builders Ohbayashi-Gumi Ltd., the US Pavilion in Osaka cost $4.50 per sq. ft. and was the largest, lightest clear-span air-supported structure ever built. A moon rock retrieved during the Apollo 11 lunar landing mission attracted 16.2 million visitors to the US Pavilion and was the most popular exhibit at the Osaka EXPO.
