Hydro Flask Launches Its First Japan-Limited “omomuki collection” with an ATELIER MATCHA Collaboration

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. In collaboration with the matcha cafe “ATELIER MATCHA by yamamasa koyamaen,” operated by TZEN Inc. (Representative Director and CEO: Chitose Nagao; location: Osaki, Shinagawa-ku, Tokyo), original menu items expressing the world of the “omomuki collection” will be offered. During the promotion, Hydro Flask’s cold-retention performance and portability will be paired with ATELIER MATCHA’s premium matcha experience to introduce customers to new ways of drinking matcha and new ways of using Hydro Flask. 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. Both items are available in matcha, akane, and karashi. The brand will also collaborate with ATELIER MATCHA, which aims to lead the third wave of matcha. At the Ginza store, from Friday, May 29 to Friday, June 12, 2026, three collaboration drinks corresponding to the collection’s three colors, karashi, akane, and matcha, will be served. These experiential menu items combine ATELIER MATCHA’s signature layered drinks with syrups inspired by each color, allowing customers to finish the drinks themselves and enjoy a new matcha experience in-store with Hydro Flask. At the Kamakura store, from Saturday, June 13 to Sunday, June 28, 2026, limited collaboration drinks will be offered for visitors strolling through Kamakura during hydrangea season. Drinks will be served in Hydro Flask bottles purchased by customers or in store-provided deposit bottles, creating a takeout-style menu that lets customers experience cold retention and portability while enjoying a new way to carry matcha with Hydro Flask around town. During the campaign, customers who purchase the “omomuki collection” through the official website or participating stores, or who order a collaboration menu item, will receive a Hydro Flask × ATELIER MATCHA collaboration sticker. The sticker reflects the world of the collection and can be used to customize a Hydro Flask. Quantities are limited and the giveaway will end once supplies run out. Hydro Flask® originated in Bend, Oregon, where a culture has taken root of hiking and enjoying coffee with scenic views before work, sharing beer with close friends after work, and camping or fishing on weekends. In 2009, when single-wall stainless-steel bottles and hard plastic bottles dominated the U.S. market, Hydro Flask® began selling insulated bottles capable of keeping drinks cold or hot. Today, the brand holds about 70% of the U.S. stainless-steel insulated bottle market, and the name “Hydro Flask®” is so well known that it is often more recognizable than the category term “insulated bottle.” All Hydro Flask® bottle products use TempShield™, a double-wall vacuum insulation technology that maintains temperature. The interior uses 18/8 pro-grade stainless steel, which resists rust and minimizes flavor transfer. The Color Last™ coating creates a distinctive texture that fits comfortably even in wet hands. A patented technology hidden in the base improves vacuum performance, reducing the need for a heavy lid and helping make the bottle lighter. The bottles also include user- and environmentally friendly features such as wide mouths and BPA-free materials. ATELIER MATCHA is a matcha cafe built around the concept of the “third wave of MATCHA,” offering an authentic matcha taste in a casual format. It was founded by Chitose Nagao, a producer involved in promoting traditional Japanese culture overseas and an associate professor of the Urasenke school of tea ceremony, together with Masayuki Koyama, a director of Yamamasa Koyamaen, the long-established tea wholesaler in Uji, Kyoto. The cafe was born from their shared desire to offer a matcha experience where people can enjoy the true taste and culture of matcha born in Japan. The event is titled “Carry omomuki with you.” Hydro Flask® “omomuki collection” × ATELIER MATCHA. The ATELIER MATCHA Ginza store event runs from Friday, May 29 to Friday, June 12, 2026, from 9:00 to 18:00. The ATELIER MATCHA Kamakura store event runs from Saturday, June 13 to Sunday, June 28, 2026, from 10:00 to 18:00. Collaboration drinks will be available only during the dates listed for each store.
