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
Tattoos must be covered with a patch in the main baths.

How it scores
Every onsen on this site is scored on the same five things.
The baths
Indoor bath
A conventional nude onsen bathhouse on the 2nd floor, plus a swimsuit-worn 'health bathing room', heated pools, a rooftop pool and a water slide. The swimsuit zone is what makes this facility unusual.

Why Agoda for Japan: it lists a lot of ryokan and small inns that the Western booking sites never picked up, and it usually prices Japanese properties in yen, so you are not paying a conversion spread on top of the room rate. Worth comparing before you book — the difference on a ryokan is often larger than you would expect.
About the day-pass link: Asoview is the main place day-use onsen in Japan sell entry tickets and discount coupons in advance. It is a Japanese-only site, so use your browser’s translation — you show the ticket on your phone at the door.
