Funagoya Onsen
Fukuoka · 船小屋温泉
Funagoya Onsen is a hot spring town in Fukuoka, Japan. The water leaves the ground at 19°C, cool enough that the baths here are usually reheated. Officially the water is classed as carbon dioxide spring and iron spring.

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.
