Ōiso Onsen

Kanagawa · 大磯温泉

Ōiso Onsen is a hot spring town in Kanagawa, Japan. The water leaves the ground at 30°C, cool enough that the baths here are usually reheated. Officially the water is classed as chloride spring.

The water here

Chloride spring 塩化物泉

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.
