Kada Awashima Onsen is a hot spring town in Wakayama, Japan. The water leaves the ground at 25.5°C, cool enough that the baths here are usually reheated. Officially the water is classed as chloride spring and bicarbonate spring.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Smooth, slightly slippery water. Often nicknamed bihada-no-yu, the water for beautiful skin.
Figures from the town's Japanese Wikipedia article.
