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.

The reason onsen fans take the train out of Tokyo into flat suburban Saitama. The source gushes out at 57 degrees and 490 litres a minute: an iodine-bearing, strongly salty sodium chloride spring (hypertonic, pH 7.5), and the tubs are filled straight from it without recirculation. Expect a heavy, salty soak that some find too strong. The setting is a residential suburb with nothing else to do nearby, but it is 3 minutes from the station.

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.

The baths

Open-air bath

Open-air bath, a second 'fine-weather' open-air bath and a lie-down bath.

Open to day visitors

Indoor bath

Indoor bath, carbonated bath and sauna.

Open to day visitors

Private (kashikiri) bath

Five private bath rooms, 5,400 yen per room for 3 hours (minimum 2 people on weekdays, 3 at weekends). The tattoo ban covers the whole facility, so they are not an option for tattooed guests.

Open to day visitors

A private bath means nobody else is in the water with you — often the practical answer if the shared baths are closed to tattooed guests.

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.

Why not the train: the last leg to an onsen is usually a local bus with nowhere to put a suitcase. A fixed-price car is booked in English and quoted before you travel, tolls and fuel included.
