Osaka Expo resources reused across Japan

The Japan Association for the 2025 World Exposition is preparing to send materials and assets from the Osaka-Kansai Expo to new users across Japan after the event closes on October 13. The effort is part of the association’s sustainability program, which says the Expo should extend the life of pavilion materials and equipment instead of treating them as one-time installations. The plan has been presented as part of the Expo’s broader “Green Expo” framework and its legacy planning. The Japan Times reported the latest details on May 20, citing association officials. ### Which Expo materials are supposed to be reused? The association’s official reuse project covers buildings, art, building materials, equipment, furniture and fixtures left after the Expo closes. On its website, the association says the program is meant to “effectively utiliz[e] resources” that remain after the event and connect them with outside demand. The matching system is called “EXPO CIRCULAR MARKET MYAKU-ICHI!,” and the association says it is designed to circulate those assets rather than discard them. The platform was introduced as part of the Expo’s sustainability push and is intended to match suppliers and recipients for post-Expo reuse. ### How does this fit into the Expo’s sustainability plan? Expo 2025 Osaka’s official sustainability materials say the event is being run under an Event Sustainability Management System and a broader action plan tied to environmental and social impacts. (expo2025.or.jp) The association says the Expo aims to use resources effectively through reduce, reuse and recycle measures and to create a legacy from the funds and materials committed to the event. The “Green Expo” section of the official site says organizers will try to reduce, reuse and recycle waste generated during and after the Expo. That places post-event reuse alongside decarbonization and renewable-energy measures as part of the event’s public sustainability agenda. ### Is this a new idea or something planned in advance? The reuse scheme predates the May 20 report. The association’s reuse matching project page was already live in 2025, and outside coverage in 2024 described the platform as a way to relocate facilities, building materials, equipment and furnishings after the Expo. (expo2025.or.jp) The official sustainability action plan also makes clear that legacy planning was built into Expo preparations years before the event opened. (expo2025.or.jp) The document says the association formulated the plan to return value to the public and society and to manage the long-term effects of a large international event. ### What does “reuse across Japan” mean in practice? (expo2025.or.jp) The association has framed the project as a national matching system rather than a single Osaka clean-up operation. Its reuse page says the goal is to connect remaining Expo resources with people and organizations that can use them after the event, which points to schools, municipalities, companies and other institutions as likely recipients, though the page does not list final destinations item by item. (expo2025.or.jp) A later Yomiuri report on post-Expo disposal and reuse said the association’s Green Vision set a target tied to the reuse of more than 17.5 pavilions, counting full relocations and partial material reuse under a scoring method. That report was published after the Expo, but it indicates organizers were measuring reuse in concrete terms rather than only as a general principle. ### What happens next after the Expo closes? (expo2025.or.jp) October 13 is the closing date for Expo 2025 Osaka, and that date is the trigger for the association’s post-event reuse phase. After closure, materials listed through the reuse matching project are expected to move through the “MYAKU-ICHI!” system to new users, while the broader Green Expo program continues to govern disposal, recycling and preservation decisions.

Assets that are not reused are also meant to be handled under recycling and waste-reduction targets set out in the Expo’s sustainability framework. (expo2025.or.jp 1) (expo2025.or.jp 2)
