The renovated spa, "Spa Casa Blanca," embraces the concept of "Wa Kei Yo San" (respecting Japanese traditions, praising Western culture), merging the "traditional hospitality" inherited from Japan's oldest established inn with ageless skincare featuring "platinum colloid" derived from cutting-edge technology, "platinum vuvu" (https://vuvu.co.jp/).

After warming the body in the public baths – the "Shiki no Yu" with its magnificent views of Kinugawa River on the first floor, and the "Kodai Hinoki no Yu" scented with two-thousand-year-old cypress (bath times are staggered) – guests can proceed directly to the second-floor treatment area. In two treatment rooms overlooking the Kinugawa valley, guests can experience platinum treatments utilizing the effects of specially processed colloids (microparticles) that have earned patents in 11 countries for their contribution to "mental and skin health."
