Osaka Expo 2025 Japan Pavilion, Expressed as a Living Organism
Nendo’s Nikken Sekkei and Oki Sato have unveiled their design for the Japan Pavilion at Osaka Expo 2025. The building is a self-supporting structure that embodies the idea of continuous transformation and reuse.Conceived as a living organism, the pavilion has a monumental ring-like shape formed by layers of cross-laminated timber arranged in translucent forms . This rhythmic façade encompasses multiple entrances and exits, with gaps providing glimpses into the biodegradable energy system and exhibition spaces within, suggesting an understanding of what’s “in between.” This is a specific principle of the structure’s theme of eternal connectivity, with no beginning or end.The pavilion’s commitment to event and sustainability continues to evolve by introducing a modular system using panels that can be easily disassembled and reused in buildings across Japan after the event period has ended.

Sato Oki and Nikken Seikei Develop Reusable Modular Wood Structures
Composed of three interconnected zones, the pavilion’s circular path reveals different aspects of the circular theme, allowing for a slightly different experience each time you visit. First, by prioritizing reuse, environmental impact, and experiential storytelling, Oki Sato and Nikken Design present an approach that allows this temporary structure to expand beyond its original use, adapting to new contexts and continuing its life cycle after the end of Osaka Expo 2025.
Rethinking traditional, static exhibition spaces , the architects envisioned a “living” pavilion as a biogas plant that processes waste generated from the expo site itself. The installation explores the process by which microorganisms break down organic waste to create biogas that powers the structure, and is expressed in an interactive installation that encourages active participation .
