Ofuro Café Karinnoyu, the hot spring and sauna facility located within THE FARM Farm Resort in Katori, Chiba, is celebrating its 4th anniversary on April 28, 2026. The highlight of the occasion is the expansion of the men's outdoor cold baths from 2 to 4 units, along with a series of special events and campaigns running throughout April.
4th Anniversary Highlight: Men's Outdoor Cold Baths Expanded to 4
The standout addition for the 4th anniversary is the expansion of the men's outdoor cold baths from 2 to 4 units. Two of the four cold baths will be designed for full submersion, allowing guests to submerge completely, including their heads. The upgrade aims to create a smoother transition from sauna to cooldown to outdoor relaxation, enhancing the quality of the "totonou" recovery experience for sauna-focused visitors.
