The Tottori Prefecture Seibu Administrative Management Union (Managing Director: Ryuji Iki), a partial administrative union composed of municipalities in western Tottori Prefecture, and Market Enterprise Co., Ltd. (Chuo Ward, Tokyo; President and CEO: Yasuji Kobayashi; TSE Standard Market, Securities Code 3135, hereinafter "Market Enterprise") have concluded an agreement on reuse initiatives aimed at addressing regional social challenges, launching their collaboration starting June 29, 2026 (Mon). Utilizing "Oikura," a reuse platform operated by Market Enterprise, the partnership aims to establish a system for reusing unwanted items instead of discarding them, targeting waste reduction and the advancement of a circular society across Yonago City, Sakaiminato City, Higashi-Harima Village, Daisen Town, Nanbu Town, Hoki Town, Hino Town, Hino-cho, and Kohoku Town. ■ Background and Context The Tottori Prefecture Seibu Administrative Management Union has previously implemented initiatives toward achieving the SDGs, such as distributing unwanted items brought to recycling centers to interested recipients through lotteries. However, the Union has recognized several challenges: increasing costs associated with waste disposal, a growing number of residents—especially the elderly—facing difficulties transporting non-combustible waste, and the fact that many discarded items could still be reused. To address these issues, the Union has been exploring new measures to raise awareness and promote reuse activities among residents. Meanwhile, Market Enterprise has been expanding its online-based reuse business, focusing on initiatives that transcend public-private boundaries under its vision of "becoming an optimization trading company that realizes a sustainable society." This includes participation in the "Regional Revitalization SDGs Public-Private Partnership Platform" and serving as a member of the "Musical Instrument Donation Furusato Tax" executive committee.
