Obama Onsen

Nagasaki · 小浜温泉

Obama Onsen is a hot spring town in Nagasaki, Japan. The water leaves the ground at 105°C, hot enough that it has to be cooled before anyone can get in. Officially the water is classed as chloride spring. Its sources put out around 15,000 litres a minute. 16 inns take visitors here.

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.
