Many traditional onsens still have strict 'no-tattoo' policies. If you have visible tattoos, look for 'tattoo-friendly' facilities or use adhesive bandages to cover smaller ink.

Can I wear a swimsuit?

No. Unless you are at a mixed-gender 'konyoku' facility that specifically provides or requires bathing suits, you must be naked.

What if I feel lightheaded?

Drink plenty of water before and after, and limit your soak to 10-15 minutes at a time. If you feel dizzy, exit immediately and sit in a cool area.

Onsen Etiquette: A Step-by-Step Guide for Japanese Hot Springs

Proper onsen etiquette centers on total cleanliness before entering the water and complete nudity while inside. You must wash thoroughly at the shower stations and keep your towel out of the bathwater at all times to maintain hygiene.

Remove your shoes. Leave your footwear in the locker or cubby at the entrance. Never wear shoes, slippers, or socks beyond this point.
Strip down completely. Onsens are strictly nudity-only zones. You will be given a small modesty towel; keep this in your hand, but it must never touch the hot spring water.
Wash thoroughly before entering. Sit on the provided stool at the washing station. Scrub your entire body with soap and rinse off every bit of lather before getting into the bath. If you have long hair, tie it up so it does not touch the water.
Enter the water slowly. The water is often very hot (40-42°C/104-108°F). Enter slowly to let your body adjust and avoid startling others.
Keep your towel out of the water. Place your small towel on your head or on the edge of the tub. It is considered unhygienic to let the towel touch the bathwater.
