What if I have tattoos?

Many traditional onsens still ban visible tattoos. If you have them, look for 'tattoo-friendly' facilities or use adhesive bandages to cover smaller tattoos before entering.

Can I wear my underwear in the bath?

No. You must be completely nude. Bringing any textiles—including swimsuits or underwear—into the water is considered unhygienic.

Should I bring my own towel from my hotel?

If you are staying at a ryokan, use the towel provided in your room. If visiting a public bath, you can usually rent a towel at the front desk for a nominal fee.

How to Navigate Onsen Etiquette: What to Wear and Not Wear

You wear nothing but your birthday suit in the water. Keep a small modesty towel to cover your front while walking, but never let it touch the water inside the bath.

Dressing in the changing room. Remove all clothing and store it in the provided basket or locker. You are expected to be completely naked; swimsuits are strictly prohibited in the bathing area.
Using the modesty towel. Take the small white hand towel provided by the facility. You may use this to cover your body while walking from the changing room to the bath area. Once you reach the edge of the water, set it aside on a ledge or stack it on your head.
The pre-bath shower. Sit on the provided plastic stool and scrub your body thoroughly with soap before entering the bath. Do not enter the communal water until you are completely clean.
Entering the bath. Slowly step into the water. Ensure your hair is tied up or pinned so that it does not touch the bath water.
