Susobanakyō Onsen is a hot spring town in Nagano, Japan. The water leaves the ground at 44.3°C, hot. It measures pH 7.2 — close to neutral. Officially the water is classed as chloride spring. Its sources put out around 1,500 litres a minute. 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.
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.
