The Grand Ring is the symbol of Expo 2025 Osaka, Kansai, Japan and expresses the concept of “Unity in Diversity.”
It is constructed using a fusion of modern construction methods and traditional Nuki joints, such as those used in the construction of Japanese shrines and temples.
It will serve as the main route of visitor traffic around the Expo site, enabling smooth movement around the site and offering visitors a comfortable space sheltered from the wind, rain, and sunlight.
