① Used Stainless Steel Vacuum Flask Collection Service
Since May 2023, the company has been operating a collection service at its directly managed stores to recycle used stainless steel vacuum flasks, targeting bottles, tumblers, cups, and soup jars with a stainless steel vacuum flask structure. In fiscal 2025, collection points were expanded to sports facilities operated by partner professional sports teams and home game venues. This resulted in an annual collection volume of approximately 2,200 kg, bringing the cumulative collection volume since the service started to approximately 3,900 kg. The company will continue its efforts towards a circular economy together with customers and partners.

[Results]
■ Cumulative collection volume of used stainless steel vacuum flasks: Approx. 3,900 kg (equivalent to approx. 18,000 vacuum-insulated portable mugs *1)
■ Collection period: May 2023 – May 2026
■ Collection locations (*2): Thermos directly managed stores (Thermos Styling Store: 4 stores, Thermos Store: 18 stores), sports game venues (Kawasaki Frontale home games, Alvark Tokyo home games), other event venues, sports facilities, etc.
■ Target products: Used bottles, tumblers, cups, and soup jars with a stainless steel vacuum flask structure (vacuum insulation structure), including those from other companies.

② Full-scale Introduction of a Drink Container Reuse Service
In October 2025, the company fully launched a drink container reuse service. This service aims to reduce disposable containers at home game venues by lending out reusable "vacuum-insulated tumblers" free of charge. It was fully introduced at the home games of "Alvark Tokyo" at their new home arena (TOYOTA ARENA TOKYO), and the number of service users per game increased as the season progressed. Customers have praised not only the environmental consideration but also the ability to keep drinks cold during the game thanks to the vacuum insulation effect. The return rate for reusable containers in the 2025-26 season was approximately 99%, marking the first step towards establishing a continuously used service.

[Results]
■ Cumulative number of loans (disposable containers reduced): Approx. 3,100 units
■ Total number of users: Approx. 1,800 people (Period: October 2025 – April 2026, implemented at home games)
