Osaka · Kansai Expo Japan Pavilion

Basic Concept and Theme
• The Japan Pavilion (also known as the Japan Government Pavilion) is a key pavilion at the 2025 Osaka Kansai Expo (EXPO 2025) and serves as a flagship showcase for host country Japan to the world.
• The theme, "Inochito, Inochino, Aidan" ("Between Life and Life"), emphasizes the concept of "circularity"—the continuous flow and interconnectedness of all things as they shift roles and forms.
• The Japan Pavilion aims to encourage audiences to consider the possibility of a "circular society" by showcasing Japan's practices and vision in environmental protection, resource utilization, and technological innovation.

Structure and Architectural Features
• The building's exterior features a circular structure, with multiple wooden panels arranged in a circular pattern, creating a sense of "encirclement" and "intertwining" spaces.
• Constructed using 560 CLT (Cross-Laminated Timber) panels, the pavilion is designed to balance aesthetics with the potential for reuse after disassembly.
• The pavilion was built with the goal of future reuse and disassembly (after closing), resulting in a sustainable design approach in its structure and material selection.
• The gaps between the panels allow for a subtle sense of light, sound, and people inside and outside the pavilion, creating a "blurred boundary" experience.

Exhibition Content and Experience Areas

The Japan Pavilion's exhibitions are divided into three thematic areas, showcasing the transformation from waste to resources through a circular process:
1. Plant Area
The processing and decomposition stage. This exhibit showcases how waste generated at the venue is decomposed by microorganisms to generate resources such as water and gas.
2. Farm Area

The production stages of algae, plants, and materials. This exhibit showcases the process of transforming water and trace resources into usable materials and substances.
3. Factory Area

The finished product and application stages. Based on traditional Japanese crafts and innovative technologies, this exhibit showcases how these materials are used in design, manufacturing, and everyday life.

Through these three areas, visitors can understand the cycle of "waste → water → materials → objects" and reflect on their own roles and responsibilities within this cycle.

In addition, the Japan Pavilion has three entrances and exits, allowing visitors to experience different "storylines" depending on their experience.

The pavilion also features special exhibits, such as the "Martian Meteorite," which is being shown for the first time, connecting technology and nature.
