Akaishi Onsen is a hot spring town in Yamanashi, Japan. The water leaves the ground at 12°C, cool enough that the baths here are usually reheated. Officially the water is classed as iron spring and acidic spring. Its sources put out around 5 litres a minute.

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.
