The water here

Chloride spring 塩化物泉

Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.

Sulfate spring 硫酸塩泉

Clear water with a faintly bitter taste. Known for holding heat.

Sulfur spring 硫黄泉

The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.
