Kamakura Sauna "Onari Sauna" to Host Running Event in Collaboration with Swiss Sports Brand "On" on Sunday, July 26, 2026

Onari Sauna (Onari Sauna), produced by GREENING Co., Ltd. (Shibuya-ku, Tokyo, CEO: Masato Sekiguchi) and operated in conjunction with Kayac Inc. (Headquarters: Kamakura City, Kanagawa Prefecture, CEO: Daisuke Yanagisawa, TSE Growth: 3904), will hold a special event combining running and sauna in collaboration with the Swiss-born sports brand "On" on Sunday, July 26, 2026. This event will feature a program that combines a TryOn experience of On's popular running shoe "Cloudmonster 3," a group run of approximately 7km along the Kamakura coast, and a sauna experience at Onari Sauna. Participants can enjoy the exhilaration unique to post-exercise and deep relaxation by seamlessly connecting "running" and "getting into the zone."

After running with On, get deeply into the zone at Onari Sauna.

Sauna indoor bathing area

Onari Sauna offers a "getting into the zone experience" that sets it apart from conventional saunas, with its "steam design" that prevents stuffiness and its unique "human löyly" that creates a deep sense of immersion. The sauna room is equipped with the electric steam generator "MAD ENGINE" and a proprietary intake system. By precisely controlling the flow of steam, it creates a warm environment that is both intensely hot and easy to breathe in. Additionally, a unique "human löyly" is performed, where cold water is poured over the entire body at the moment body temperature and heart rate rise. This temporarily cools the body while remaining in the sauna, allowing for deep warming of the body.

Rooftop terrace

Afterwards, the path from the cold bath to the rooftop outdoor bathing space leads to a state of deep relaxation. In the open rooftop space where a pleasant breeze blows, you can enjoy Onari Sauna's unique "getting into the zone" experience while feeling the sky and the outdoors all over your body.

Experience the run of Cloudmonster 3 while feeling the Kamakura breeze

Cloudmonster 3

The Cloudmonster 3 is the latest model that further evolves the ride feel of the first-generation model, which was supported by many runners, making the feet naturally push forward. Equipped with the proprietary cushioning technology "CloudTec®" updated to a three-layer structure, it achieves excellent repulsion and cushioning. It supports a comfortable running experience with comfortable landings and powerful propulsion. This event offers a "TryOn" experience where you can run approximately 7km along the Kamakura coast while actually wearing the Cloudmonster 3. You can enjoy the light and comfortable running feel unique to On, along with the rich natural scenery of Kamakura.
