The water here

Iron spring 含鉄泉

Turns reddish brown as the iron meets air. The water is clear at the source.

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.
