Mikawa Onsen is a hot spring town in Niigata, Japan. The water leaves the ground at 40–43°C, hot. Officially the water is classed as chloride spring and sulfate spring. Its sources put out around 349 litres a minute. 6 inns take visitors here with room for about 247 guests. About 2,049 people a year come to bathe.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Sulfate spring 硫酸塩泉
Clear water with a faintly bitter taste. Known for holding heat.
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.
