Osaka Expo 2025 – Sou Fujimoto
The Grand Ring, designed by Sou Fujimoto Architects for Expo 2025 Osaka, is the world’s largest wooden architectural structure at 61,035 square metres, as recognized by Guinness World Records. It encircles the Expo with a 2-kilometre circumference and a 700-metre diameter, symbolizing global unity. Built using traditional Japanese joinery like Nuki joints, the modular, dismantlable structure incorporates 70% domestically sourced cedar and cypress, with the rest being Scots pine. The elevated Ring Skywalk, rising 12 metres, includes upper and lower levels for panoramic views of Osaka and Osaka Bay, and offers shelter from the elements while serving as the Expo’s main circulation route.
