Shinagawa City, Tokyo, Starts Partnership with "Oikura" for Unwanted Item Reuse Project, 13th Introduction in Tokyo's 23 Wards

Market Enterprise Co., Ltd. (Chuo-ku, Tokyo; Representative Director and President: Yasushi Kobayashi; TSE Standard: Securities Code 3135; hereinafter "Market Enterprise") and Shinagawa City, Tokyo (Mayor: Kyoko Morisawa), have signed an agreement regarding a reuse project aimed at solving community issues, and will commence their collaboration on May 1, 2026 (Friday). By utilizing "Oikura," a reuse platform operated by Market Enterprise, a system will be established to reuse unwanted items instead of discarding them, with the goal of reducing waste in Shinagawa City and forming a circular economy.

■ Background and History
Shinagawa City has been actively promoting reuse activities, such as publishing information on the transfer of unwanted items and consignment sales of unwanted items, aiming to reduce bulky waste by approximately 18.7 tons in FY2025. However, the city felt it was a challenge that many reusable items were included in discarded waste, and was considering introducing new reuse measures to raise awareness and promote reuse activities among residents. On the other hand, Market Enterprise has developed internet-based businesses primarily focused on reuse, and has consistently focused on SDGs initiatives transcending public and private sectors, such as participating in the "Local Revitalization SDGs Public-Private Partnership Platform" and continuing activities as a member of the "Musical Instrument Donation Furusato Nozei" Executive Committee, under the vision of "an optimized trading company that realizes a sustainable society." Amidst this, Market Enterprise approached Shinagawa City, and their mutual needs to "aim for the formation of a circular economy through the promotion of reuse activities" converged, leading to the realization of this initiative using "Oikura" *1.

*1 What is "Oikura"?
Oikura is a reuse platform developed by Market Enterprise. When individuals who want to sell unwanted items request an assessment through "Oikura," a collective assessment request is sent to affiliated reuse shops nationwide, allowing users to compare purchase prices, dates, methods, and reviews. Its ease of use, allowing users to compare assessment results for unwanted items and sell them with just one request, has been well-received, and approximately 1.68 million people (as of the end of February 2026) have used the service to date.

■ Shinagawa City's Challenges and Solutions by "Oikura"
Shinagawa City collects bulky waste for a fee through pre-booked individual collection or self-delivery to the Shinagawa City Resource Recycling Center. However, residents are generally required to carry large or heavy items out of their homes. "Oikura" offers an on-site purchase service where, if desired, they will visit the home and handle the removal of items, making it easy to sell large or heavy items. In addition, products subject to the Home Appliance Recycling Law, such as refrigerators and washing machines, may also be purchased if they are still usable. By requesting a purchase through "Oikura," it is possible to sell and hand over unwanted items as early as the same day. Furthermore, there is no cost to residents for using the service, nor is there any financial burden on the city.

■ Future Outlook
Information about "Oikura" will be posted on the Shinagawa City website
(https://www.city.shinagawa.tokyo.jp/PC/kankyo/kankyo-gomi/gomi-sodai/20240807165625.html) on May 1st (Friday) at 3:30 PM (posting time may vary), enabling direct bulk assessment requests for unwanted items. The collaboration between Shinagawa City and "Oikura" is expected to further revitalize secondary circulation, realize a circular economy, reduce unwanted items across society, and contribute to reducing the amount and cost of waste processing for local governments. Furthermore, by making residents aware that they can easily reuse unwanted items through sales via this initiative, the option to "reuse instead of discard" will increase, meeting diversifying needs for unwanted item disposal. This will also lead to a change in residents' awareness of reuse and promote the formation of a circular society. Through this public-private initiative, we aim to solve both the social and economic challenges related to forming a circular economy.

■ Shinagawa City, Tokyo
Shinagawa City is composed of a waterfront area facing Tokyo Bay and a plateau connected to the Yamanote area. It has prospered as a hub for transportation and trade since ancient times and possesses numerous historical sites, including the "Omori Shell Mounds," known as the birthplace of archaeology. During the Edo period, it flourished as "Shinagawa-shuku," the first post town on the Tokaido road, and since the Meiji era, it has developed as the birthplace of the Keihin Industrial Area. In modern times, against the backdrop of the internationalization of Haneda Airport and the development of long-distance bus networks, it plays an important role as a gateway to Tokyo, an international city. In addition to the development of the waterfront area utilizing its waterscape, it is also planned to be the starting station for the Chuo Shinkansen Maglev line in the future.
