OSAKA: The grand roof of the 2025 World Exposition venue in Osaka has officially been recognised as the world’s largest wooden architectural structure by Guinness World Records. The massive structure, known as the Grand Ring, symbolises unity and connection at the upcoming global event, set to begin on April 13.

Spanning an area of over 61,000 square metres, the roof was designed to reflect the Expo’s theme of “Unity in Diversity.” Architect Sosuke Fujimoto, speaking at the award ceremony, expressed his hope that the landmark structure would inspire a sense of connection in a world facing increasing divisions.

Completed on February 27, the architectural marvel stands up to 20 metres high, with a circumference of approximately 2 kilometres. It was constructed using around 27,000 cubic metres of timber, including Japanese cypress, cedar, and European red pines. The structure is a testament to sustainable architecture and traditional craftsmanship, blended with modern engineering.

With the Osaka Expo expected to draw millions of visitors, the Grand Ring serves as a powerful symbol of innovation and environmental consciousness. It highlights Japan’s commitment to sustainability while showcasing the beauty and versatility of wood in large-scale construction.

The six-month-long Expo will bring together nations from around the world to share ideas and technologies for a better future, and this record-breaking structure sets the tone for an event focused on progress and global unity.
