Onsen Etiquette: How to Soak the Japanese Way

First time visiting an onsen? It’s natural to feel unsure about what to do, what to wear — or not wear — and how to behave. Onsens are a cherished part of Japanese culture, and following a few simple rules will help you feel comfortable and show respect to the people around you.

Tattoos

Tattoos have traditionally been forbidden in onsens because of their association with organized crime. While some facilities in international resorts like Niseko are more relaxed today, there is no single rule that applies everywhere. Some onsens may welcome tattooed guests, while others still deny entry. It’s always best to check the policy before visiting, and be prepared that rules can change without notice.

Shower First

Cleanliness is central to the onsen experience. Before stepping into the bath, you must shower thoroughly at the washing stations provided. Sit on the stool, use the soap and bucket, and rinse yourself completely. The idea is to enter the shared mineral water perfectly clean, so that everyone can enjoy it.

What to Wear (and Not Wear)

Traditional onsens do not allow clothing or swimsuits in the baths. The only item you’ll carry is a small towel for modesty while walking between the changing room and the pool. Once you’re in the water, place the towel on your head or leave it outside the bath. Letting it touch the water is considered unhygienic. In some mixed-gender baths, special bathing wear may be provided, but otherwise, simplicity is the rule.

How to wear your hair?

If you have long hair, tie it up before soaking. Hair should never trail in the bathwater, both for hygiene and out of respect for fellow bathers. Many locals bring a hair tie or use a small towel to keep it neatly out of the way.

Keep Quiet – So Everyone Can Unwind

Onsens are about relaxation, so quiet conversation is fine, but shouting or boisterous behavior isn’t. This is especially true in the sauna, where silence is part of the ritual. Think of the atmosphere as more like a library than a swimming pool.

No Food, Drink, or Phones

Eating and drinking are not permitted in the bathing areas, and phones are absolutely off-limits in public onsens. Taking photos is completely prohibited, and electronics don’t mix well with steam anyway. If you’ve booked a private onsen, of course, you’re free to relax however you like.

Dry Off Before Changing

When you’re ready to leave, take a moment to dry yourself with your towel before stepping back into the changing room. This small act of courtesy keeps the space clean and comfortable for everyone.

Final Thoughts

Onsen etiquette may seem like a lot to take in, but once you understand the basics, it becomes second nature. At its heart, the ritual is about respect — for the water, the space, and the people sharing it with you. Don’t stress too much about getting everything perfect. Relax, breathe deeply, and let the mineral-rich waters do what they’ve done for centuries: restore body and mind.
