Promoting Activities Through a Three-Way Partnership

The signing ceremony was attended by Gotsu Mayor Ataru Nakamura, HOYA Eye Care Company President Akira Takenaka, and Umi to Nippon Project in Shimane Board Member Hideki Yamazaki.

The Umi to Nippon Project in Shimane promotes local cleanup activities and organizes unique events to achieve "zero marine litter." Approximately 80% of marine debris originates from cities and rivers, with the majority being plastic. As part of its environmental conservation efforts, the project is collaborating on this collection initiative in Gotsu City.

The "eyecity eco project," which began in 2016, uses dedicated collection boxes to gather empty cases, which are then recycled into materials for home appliances, automotive parts, and ballpoint pens.

HOYA Eye Care Company President Akira Takenaka expressed his hopes for the project's expansion, stating, "Through this agreement, we hope to raise awareness among many people and accelerate our activities."

Collection boxes have been placed at the Citizen Life Division on the first floor of Gotsu City Hall to encourage participation from citizens and city staff.

Mayor Nakamura noted, "Gotsu City aims to be a 'Zero Carbon City' where industry and nature harmonize, and this activity contributes to waste reduction and climate change countermeasures."

This is the second such tripartite agreement in Shimane Prefecture, following a similar initiative in Matsue City in 2022.
