Free-flow from source
Tarumae Onsen
A natural hot spring with a sodium-chloride strong saline spring flowing from 1,500 m underground. With a salt concentration close to seawater, it is expected to have excellent heat-retention and moisturizing effects as a salt film envelops the skin after bathing. In the open-air bath, you can fully enjoy rich, cloudy water straight from the source and spend a deeply restorative moment for both body and mind, together with the spectacular view of Mount Tarumae spread out before you.
