Expo 2025 Osaka has officially opened on April 13, 2025, at Yumeshima, Osaka. Under the overarching theme "Designing Future Society for Our Lives," the Expo set out to explore three pivotal subthemes: Saving Lives, Empowering Lives, and Connecting Lives. These themes aim to unite architectural and design enthusiasts by demonstrating how cutting-edge technology and innovative solutions can address global challenges, foster dialogue inspire collective action.


The Expo will span 184 days, from April 13 to October 13, 2025, transforming Yumeshima, a reclaimed site in Osaka Bay, into a hub of international collaboration and experimental architecture. The master plan, designed by Sou Fujimoto to embrace the natural beauty of the sea and sky, emphasizes "Unity in Diversity." It aims to unite the different sections of the World Expo through the introduction of the main architectural element of the event: the prominent Grand Ring, also designed by Sou Fujimoto, which has now become the largest wooden architectural structure in the world, according to the organizers.
The Grand Ring integrates modern construction techniques with traditional Japanese Nuki joints, creating a blend of innovation and heritage. As the heart of the Expo, it will facilitate intuitive movement across the site, providing a comfortable and accessible experience for all visitors, while sheltering them from the elements.
