Hot Spring & Bath Information

Bath

TypeNatural Hot Spring

Flow-through

A very rare natural hot spring in Hokkaido that is true source flow-through, with no added water and no circulation filtration at all. The sodium chloride strong saline spring, with its high salt content, leaves salt on the skin when you soak, helping prevent sweat from evaporating and giving it outstanding heat-retention effects to the point that it is called a hot bath. In addition, the tea-brown water contains molasses ingredients associated with skin-beautifying effects and minerals that help keep the skin healthy. It generously fills the newly built spacious open-air bath and the variety of indoor baths, gently warming and loosening the body from deep within.
