Construction is well underway on a massive circular wooden structure off the coast of Japan in preparation for Expo 2025 Osaka. Designed by renowned architect Sou Fujimoto, the structure will have a diameter of 700 meters and will enclose the site of the upcoming World Expo on the artificial island Yumeshima in Osaka Bay.
This architectural marvel, spanning 60,000 square meters, aims to symbolize the unity of all nations by creating a connection through “one sky.” Developed by Sou Fujimoto Architects in collaboration with Tohata Architects & Engineers and Azusa Sekkei, the structure is set to become a major attraction during the six-month-long Expo, scheduled to open on April 13, 2025.
Fujimoto drew inspiration from traditional Japanese timber construction, particularly the iconic Kiyomizu-dera temple in Kyoto, when designing the wooden ring. In addition to serving as the main circulation route for the masterplan, the structure will also provide shelter from the elements, including rain and intense sun. It will feature walkways and a rooftop observation deck adorned with seasonal landscaping.
Inside the wooden circle, visitors will find a spectacle of pavilions created by architects from participating nations. Divided into three zones known as Pavilion World, Water World, and Green World, the Expo 2025 Osaka site will also include several plazas to host various events.
One of the pavilions to be showcased at the Expo has already been revealed on Dezeen. Designed by Shigeru Ban, the pavilion will have an undulating form and will be constructed using paper tubes, bamboo, and carbon-fiber-reinforced plastic.
Expo 2025 Osaka is part of the World Expo series, which takes place every five years. The previous edition, Expo 2020 Dubai, had to be postponed to 2021 due to the global pandemic. The event featured pavilions designed by renowned architects such as Santiago Calatrava and Foster + Partners.
As construction progresses on this awe-inspiring wooden structure, Expo 2025 Osaka is set to become a must-visit destination for architecture enthusiasts and global citizens alike.
