One ring. Endless perspectives. ✨
The Grand Ring takes its place among the iF DESIGN AWARD 2026 Gold winners, becoming the defining architectural symbol of Expo 2025 Osaka and a powerful expression of “Unity in Diversity.”
Built using a fusion of modern construction methods and traditional Japanese Nuki joints, the structure draws inspiration from the craftsmanship of shrines and temples. At the same time, it creates a contemporary space designed for gathering, movement and connection.
Designed as the main circulation route across the Expo site, the elevated ring opens up sweeping views of the pavilions below while offering shelter from wind, rain and sunlight. Its CLT construction and demountable detailing reflect a thoughtful approach to circular architecture and temporary design with lasting impact.
An architecture that brings people, cultures and ideas into one continuous connection.
