Osaka Expo 'Grand Ring' a symbol of unity – architect
ITS creator says that a towering wooden «Grand Ring» built for Expo 2025 in Osaka pays homage to Japan's architectural history and is a symbol of unity despite criticism over costs. The 2-kilometer (1.2-mile) circumference of Sou Fujimoto's striking structure will surround dozens of national pavilions at the six-monthlong event from April.
