Arima Onsen

The water here
Chloride spring
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Bicarbonate spring
Smooth, slightly slippery water. Often nicknamed bihada-no-yu, the water for beautiful skin.
Iron spring
Turns reddish brown as the iron meets air. The water is clear at the source.
Radioactive spring
Contains trace radon that leaves the water quickly. Also called radium or radon springs.
