Kitsuregawa Onsen is a hot spring town in Tochigi, Japan. The water leaves the ground at 50°C, hot. Officially the water is classed as chloride spring and sulfur spring. Its sources put out around 268 litres a minute. 2 inns take visitors here.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Sulfur spring 硫黄泉
The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.

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.
