Tattoos not allowed (day visit)

Can you bathe here with a tattoo?

This is the question we built the site around, so we answer it per situation.

Visiting for the day

No — tattooed guests are turned away

Guests with tattoos are refused entry to the facility, so private baths are not an option either.

A day-use bathhouse built for one thing: an open-air bath facing straight out at the Pacific, with a view restaurant serving the local catch above it. The water is what the operator calls ancient fossil seawater, which makes it a heavy salt bath rather than a bland one, though no spring analysis is published. Tattoos are refused at the door, in writing, with no private-bath exemption.

Every onsen on this site is scored against the same written rubric, and every score has been reviewed by the editor. The ones marked Visited were also bathed in personally.
