Free-flow from source
Nakashibetsu Onsen
This is 100% free-flowing water from a private source that the hotel drills and manages itself. It is a sodium chloride hot spring (alkaline, hypotonic, high-temperature spring), and its distinctive silky bath feel is beloved as a beauty-enhancing hot spring. It keeps you warm for a long time and is less likely to leave you chilled after bathing. In the open-air rock bath, you can enjoy the crisp Hokkaido air and the grand mountain scenery while savoring blissful bathing time.
