A Monumental Wooden Marvel at Expo 2025
The Grand Ring, unveiled at Expo 2025 in Osaka, Japan, stands as the world’s largest wooden architectural structure. Designed by renowned Japanese architect Sou Fujimoto, this monumental circular walkway spans approximately 2 kilometers (1.2 miles) in circumference and covers an area of 61,035.55 square meters. Its impressive scale has earned it official recognition from Guinness World Records as the largest wooden architectural structure globally.
Engineering Meets Tradition
Constructed on Yumeshima, an artificial island in Osaka Bay, the Grand Ring serves as the central circulation route for Expo 2025. Its design incorporates traditional Japanese “nuki” joinery techniques, often seen in shrine and temple construction, blended seamlessly with advanced modern engineering. This combination celebrates Japan’s cultural heritage while promoting sustainable architecture.
A Walk Above the Future
Elevated 12 meters (about 40 feet) above ground level, the structure features a “Sky Walk” lined with diverse plant life and flowers. This scenic pathway offers visitors panoramic views of the Expo’s pavilions and surrounding landscapes. The design also provides shelter from sun and rain, enhancing visitor comfort and accessibility.
A Symbol of Unity and Innovation
More than just a walkway, the Grand Ring embodies the theme of Expo 2025: “Unity in Diversity.” Its circular design signifies harmony, interconnectedness, and the unbroken flow of ideas and cultures. As both an engineering feat and a cultural icon, the structure represents a global vision of sustainability and creative collaboration.
