Higashihidaka Onsen
A sodium-calcium sulfate hot spring drawn from nearby Higashihidaka Onsen, with low-tonicity and alkaline properties. The source temperature is 36°C, so it is heated and circulated, but with a pH of 9.55 it has a smooth, silky feel on the skin. It is said to help with neuralgia, muscle pain, joint pain, and sensitivity to cold, and its warmth lasts long after you leave the bath. You can enjoy this water in a variety of settings, including the open-air bath overlooking the giant serpent sculpture on the roof, as well as the shrine-style wooden bath and the mystical rock bath.
