In September 2023, construction images of the wooden ring roof in Japan by architect Sou Fujimoto had surfaced for the very first time. Designed as the master plan for the highly-anticipated Expo 2025 Osaka, the proposal reveals a 60,000 sqm green-filled structure that will serve as the international fair’s main circulation path. As we inch closer to the event, which will be held between April 13 – October 13, 2025, the Japanese architect shares new pictures showing the impressive progress happening on the ground.

Structurally, the wooden ring roof for Expo 2025 Osaka varies between 12 meters and 22 meters in height, spans about 600 meters in diameter, and stretches for two kilometers around. Construction is held jointly with  Tohata Architects & Engineers and Azusa Sekkei. Taking to Instagram, Sou Fujimoto writes: ‘This timber construction roof is part of the main circulation of the Expo master plan, providing spectacular experiences, while protecting visitors from rain and strong sunlight. People can go up to the top of the roof where is the observatory deck, can enjoy the view to the sea and sunset. This roof is covered by greens and flowers, changing its impression season by season.’
