ARCO Co., Ltd. (head office: Osaka City, Osaka; President and Representative Director: Masahiro Furihata), the exclusive distributor in Japan for the U.S. stainless-steel bottle brand Hydro Flask®, will launch Hydro Flask’s first Japan-limited collection, the “omomuki collection,” on Friday, May 29, 2026. The collection applies nature-inspired colors to the bottle bodies and uses traditional Japanese colors for the caps and logos. The three colors, “akane,” “karashi,” and “matcha,” express Japanese elegance and beauty while retaining Hydro Flask’s signature functionality and pop sensibility, resulting in a new Japanese-Western fusion concept bottle. To commemorate the launch, Hydro Flask will hold an experiential collaboration promotion under the concept “Carry omomuki with you,” themed around matcha, which is widely recognized overseas as a symbol of Japanese culture and aesthetics. For this project, Yamamasa Koyamaen, a long-established tea wholesaler in Uji, Kyoto that dates back to the Edo period (Representative Director: Seigo Koyama; location: Ogura-cho, Uji City, Kyoto), will provide matcha, recipes, and operational know-how.

(Representative Director and CEO: Chitose Nagao; location: Osaki, Shinagawa-ku, Tokyo), original menu items expressing the world of the “omomuki collection” will be offered.

The S26 Limited Edition “omomuki collection” product lineup includes the omomuki 16oz WIDE MOUTH, priced at ¥5,500 including tax, and the omomuki 200ml MICRO HYDRO, priced at ¥4,180 including tax.
