Your First Onsen in Japan: The Steps, Tattoo Rules, Private Baths

Japan Travel, Labeled · No. 03 — Your First Onsen in Japan: The Steps, Tattoo Rules, Private Baths

You are standing in a changing room at a hot spring, towel in hand, unsure what happens next — and whether your tattoo ends the visit at the door.

This guide gives the order of an onsen visit — wash first, towel out of the water, hair up — and states the tattoo rules plainly, with the options that remain when a facility says no.

What's inside

• What legally counts as an onsen, and how a day trip differs from staying at a ryokan
• What to bring and what is provided, at a ryokan and at a day-trip facility
• The bathing steps in order: 9 steps from the entrance curtain to drying off
• 7 standing rules in the water, and the one shared-water principle behind them
• Tattoo policies as documented: the official 2015 survey of 581 facilities (about 56% refused, 31% no restriction, 13% conditional)
• Private baths (kashikiri): how they work, how long you get, and which problems they solve
• General health cautions from the official bathing guidelines

FAQ

Q: I have a tattoo. Can I use an onsen?

A: There is no law and no national rule — each facility decides. Your options, in order: check the facility's website, ask the property directly, cover a small tattoo with a sticker, or book a private bath.

Q: Can I wear a swimsuit in the bath?

A: No — shared baths are nude, and swimwear stays out. If that is a barrier, a private bath (kashikiri-buro) gives you the same water with your group only.
