Yunoami Onsen is a hot spring town in Ibaraki, Japan. The water leaves the ground at 13.6°C, cool enough that the baths here are usually reheated. Officially the water is classed as chloride spring, bicarbonate 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.
Bicarbonate spring 炭酸水素塩泉
Smooth, slightly slippery water. Often nicknamed bihada-no-yu, the water for beautiful skin.
Iron spring 含鉄泉
Turns reddish brown as the iron meets air. The water is clear at the source.
With tattoos
Many public baths still turn away visible tattoos, and the rule is set by each bath, not by the town. The reliable way round it is to bathe privately: a room with its own open-air bath, or an inn with a private bath you can book for yourselves.
