Kanno Onsen is a hot spring town in Hokkaido, Japan. The water leaves the ground at 35–86°C, hot enough that it has to be cooled before anyone can get in. Officially the water is classed as chloride spring, bicarbonate spring, sulfate spring and iron spring. 1 inns take visitors here.
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.
Clear water with a faintly bitter taste. Known for holding heat.
Turns reddish brown as the iron meets air. The water is clear at the source.
