Nikken Sekkei’s Projects for Expo 2025 Osaka, Kansai, Japan

Nikken Sekkei envisions Expo 2025 as a key step towards a circular society. Our innovative approaches include sustainable designs for temporary structures to cutting-edge digital design for large-scale landscapes.
Japan Pavilion The design embodies the “cycle of life” through simple details that feature large-format glass panels set into a circular arrangement of domestically produced CLT materials laid out in a staggered pattern. It offered an experience that seamlessly integrated “inside and outside” and “exhibition and architecture.”
