Japan Pavilion at Expo 2025 Osaka: The Poetic Cycle of Life in Wood

2025年大阪世博会以“设计未来社会，创造美好生活”为主题，吸引了全球的目光。作为东道国，日本馆以“生命之间——Between Lives”为核心理念，通过独特的设计和创新的技术，生动诠释了未来可持续发展的蓝图，成为世博会上的一大亮点。

The Expo 2025 Osaka, with its theme “Designing Future Society for Our Lives”, is in full swing, focusing on building a blueprint for future living. As the host country, Japan’s pavilion, titled “Between Lives”, carries the significant responsibility of exemplifying and vividly interpreting this theme.  

设计理念：循环与流转的象征

Design Philosophy: Symbolizing Cycle and Flow  

日本馆位于世博主轴“大环”外侧，以圆形为设计主体，采用成排交叉层压木材（CLT）构建圆环状结构。这一设计不仅美观，更象征着生命的循环与流转。木板之间的间隙让参观者能够从内外不同的视角感受建筑的连续性与间隙感，完美呼应了“生命之间”的主题。展馆通过建筑语言回答了“生命之间是什么？”的哲学命题，展现了自然世界中微小循环与相互关联的动力。

Located outside the main “Grand Ring” building of the expo site, the Japan Pavilion adopts a circular design as its main structure, constructed with cross-laminated timber (CLT) arranged in rows to form a ring-shaped framework. This design symbolizes the cycle and flow of life. The gaps between the wooden panels allow glimpses into the interior, enabling visitors to deeply experience the pavilion’s theme of “Between Lives” through the continuity and intervals between the building's inside and outside.   

可持续实践：从能源到建筑的全循环

Sustainable Practices: A Full Cycle from Energy to Architecture  

日本馆将“循环”理念贯穿于每一个细节。展馆内设有微生物分解系统，能够将世博会现场产生的食品垃圾转化为沼气发电，实现能源的自给自足。参观路径被设计为一条螺旋上升的环形走廊，沿途通过多媒体装置、藻类培育展示及互动艺术，向游客展示“循环”的多元维度。更值得一提的是，世博会结束后，建筑构件将被拆解并用于日本各地的公共项目，真正践行了“从临时到永恒”的可持续理念。

The concept of “cycle” is thoroughly embodied in the Japan Pavilion’s design. The pavilion features a microbial decomposition system that converts food waste generated at the expo into biogas for electricity, achieving self-sufficient energy circulation. The visitor path is designed as a spiraling circular corridor, where multimedia installations, algae cultivation displays, and interactive art gradually reveal the multiple dimensions of “cycle”. Additionally, after the expo concludes, the building components will be dismantled and repurposed for public projects across Japan, putting the sustainable philosophy of “from temporary to eternal” into practice.
