Grand Ring at Expo 2025 Osaka organizes the site through a 2-kilometer circular timber structure that serves as the main circulation route and architectural symbol of the event. Designed by Sou Fujimoto, the elevated walkway connects national and thematic pavilions while integrating traditional Japanese joinery techniques like nuki joints. Its rooftop is landscaped, and the structure’s materiality prioritizes local sourcing and carbon efficiency. #architecture: Sou Fujimoto Architects 📍#Japan #
