Onsen (hot springs) are one of the most magical experiences in Japan. Volcanic waters, mountain views, and a culture of relaxation that dates back thousands of years. But onsen come with a clear set of rules — and following them is essential.
These rules exist for hygiene and respect. Once you know them, they're easy to follow — and you'll feel completely comfortable.
Before Entering the Bath
1. Wash Your Body Thoroughly First
This is the most important rule. Before entering any shared bath, you must wash your entire body at the shower stations provided. Use soap and shampoo. Rinse completely. The bath water is shared by everyone — entering without washing is the biggest taboo.
2. Shower Stations
You'll find a row of low stools and handheld showers. Sit on the stool, wash thoroughly, and rinse off all soap before heading to the bath. Keep water spray directed downward to avoid splashing neighbors.
In the Bath
3. No Towels in the Water
Never put your towel in the bath water. This is a strict rule. Most people fold their small towel and place it on top of their head, or set it on the edge of the bath. The large towel stays in the changing room.
4. Enter Slowly and Quietly
Don't jump or splash. Lower yourself in gently. Onsen is a place of quiet relaxation — keep your voice low and avoid loud conversations. Many Japanese visitors come to onsen for meditative silence.
5. No Swimming
The bath is for soaking, not swimming. Stay relatively still and enjoy the warmth.

Leaving the Bath
6. Dry Off Before the Changing Room
Before returning to the changing room, wipe your body with your small towel. Don't walk back dripping wet — the changing room floor should stay dry for everyone. Ring out your towel and pat yourself down.
Sauna Rules
Many onsen facilities include a sauna. The rules are similar:
- Wipe your body before entering — don't bring bath water into the sauna
- Sit on your towel — never directly on the wooden bench
- Keep quiet — sauna is a meditative space
- Rinse off before returning to the bath after using the sauna
Other Important Rules
- Tattoos — Many traditional onsen prohibit tattoos. Look for "tattoo-friendly" onsen, or use private baths (kashikiri). See our tattoo-friendly onsen guide →
- No swimsuits — Onsen are entered naked (except mixed-gender baths where wraps may be provided)
- No phones or cameras — Photography is strictly prohibited in bathing areas
- Tie up long hair — Hair should not touch the bath water
- Don't drink alcohol before bathing — Hot water + alcohol is dangerous
Frequently Asked Questions
Can I go to an onsen with tattoos?
Many traditional onsen still prohibit tattoos, but the number of tattoo-friendly facilities is growing — especially in Kyushu. Private baths (kashikiri) are always an option, typically costing ¥2,000-5,000 per hour. Ask our team for tattoo-friendly recommendations along your route.
What should I bring to an onsen?
Most onsen provide body wash and shampoo. Bring a small towel (or rent one for ¥100-200). Some onsen charge ¥500-1,000 for entry. VanTripJapan campervans include bath towels and a Kyushu onsen guide map.
Do I need to be naked in an onsen?
Yes, onsen are entered without clothing in the bathing areas. Gender-separated baths are standard. Mixed-gender baths (konyoku) are rare and usually provide wraps. If you're uncomfortable, look for onsen with private baths.
Is it okay to put my towel in the onsen water?
No. Never submerge your towel in the bath water. Fold it and place it on your head or on the edge of the bath. This keeps the shared water clean for everyone.
