Pal System Consumers' Cooperative Union (Headquarters: Shinjuku-ku, Tokyo; Chairperson: Atsuyuki Shibusawa) participated in the "Shinjuku Future Map EXPO 2026" held on June 29, 2026 (Sun) at Obirin University Shinjuku Campus in Shinjuku-ku, Tokyo. Children who visited were encouraged to think about environmental issues starting with the plastics they encounter in their daily lives. Finding plastic fragments in beach sand At the Pal System booth, children learned about plastics familiar in their lives and about marine pollution caused by plastics. Through quizzes, the characteristics of plastics were introduced, explaining that they are indispensable to human life. It was then conveyed that plastics not reused, such as those carelessly discarded, reach the ocean and affect various living organisms. Finally, using sand actually collected from a beach, the children were asked to find microplastics broken down to the size of sand grains. The children seemed surprised to discover fragments of plastic bottle caps and artificial turf mixed in, imagining their original forms from the color and shape of the particles. First-ever project planned by students for children "Shinjuku Future Map EXPO" is an experiential event aimed at enabling children in the Shinjuku area to draw their own "future maps" in collaboration with the community, university, companies, and organizations.
