An astonishing beautifying bath with a pH of 10.0, and a forest sauna where you can enjoy self-löyly
Hokkaido Urahoro Town
"Urahoro Rushin Onsen" is a secluded inn nestled in a quiet forest in Urahoro, Hokkaido. Its biggest draw is its highly alkaline spring water, boasting a pH of 10.0, among the highest in Hokkaido. Known locally as a beautifying bath that removes dead skin cells and leaves the skin smooth, it is deeply loved by locals as well. The sauna area features a convection-style dry sauna that allows self-löyly. Though compact, it offers an authentic wave of heat, and once you step out of the sauna room, forest-fresh outdoor air bathing awaits. By alternating between the cool cold plunge bath using underground water and the strongly alkaline sulfur spring, you can enjoy a refreshing experience that leaves both body and mind feeling silky smooth.
