湯谷温泉 is a hot spring town in Aichi, Japan. The water leaves the ground at 19.5°C, cool enough that the baths here are usually reheated. Officially the water is classed as chloride spring. 9 inns take visitors here.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Figures from the town's Japanese Wikipedia article.
