Pine Create Co., Ltd. (Headquarters: Chuo-ku, Osaka), the developer of the sauna brand 'Go Relax,' will release the second installment of its collaboration items with 'Kerorin,' a beloved symbol of Japanese public baths across generations, starting this April. The items will be available at the official online shop and select retailers nationwide.
During the first release, the design of 'Mamoru-san' relaxing in a sauna against a vibrant yellow background became a hot topic on social media, gaining significant support from sauna and public bath enthusiasts. This second collection includes highly requested items such as baskets and carabiners, offering an even more comprehensive lineup.
### Background of the Collaboration
'Go Relax,' which aims to 'bring the world of sauna into daily life,' joins forces with 'Kerorin,' a long-time icon of Japanese public baths.
