How to Use a Japanese Onsen (2026 Guide for First-Time Visitors)
Thinking About Visiting an Onsen?
A Japanese onsen (hot spring) is one of the most relaxing experiences you can have during your trip. If it’s your first visit, you might be unsure about the rules—but don’t worry. Once you know the basics, using an onsen is simple and enjoyable.
What Is an Onsen?
An onsen is a natural hot spring filled with mineral-rich water from underground. You’ll find onsen at traditional ryokan, hotels, and hot spring resorts throughout Japan.
Before You Enter
- Remove your shoes before entering the changing room.
- Most onsen have separate bathing areas for men and women.
- Store your clothes and belongings in a locker or basket before entering the bathing area.
Do You Wear a Swimsuit?
No.
In almost all traditional Japanese onsen, guests bathe completely nude. Swimsuits are generally not allowed unless the facility clearly says otherwise.
Although it may feel unusual at first, it’s completely normal in Japan.
Wash Before Entering the Bath
This is the most important rule.
Before entering the hot spring, wash your body thoroughly at one of the shower stations. Shampoo, conditioner, and body soap are usually provided.
Make sure to rinse off completely before getting into the bath.
Onsen Etiquette
To help everyone enjoy a relaxing atmosphere:
- Enter the bath slowly, as the water is usually very hot.
- Keep your small towel out of the water.
- Speak quietly.
- Do not swim or splash in the bath.
- Dry off with your towel before returning to the changing room.
- Do not use phones or cameras inside the bathing or changing areas.
Babies and Diapers
Most public onsen do not allow babies wearing diapers, including swim diapers, to enter the communal bath.
If you’re traveling with a baby, check the facility’s policy in advance or consider booking a private family bath (kashikiri onsen), which can be a great option for families.
What If You Have Tattoos?
Some onsen welcome guests with tattoos, while others do not. Policies vary by facility, so it’s always best to check before your visit.
If you have tattoos, consider choosing a tattoo-friendly onsen or booking a private bath.

Common Mistakes to Avoid
- Entering the bath without washing first
- Wearing a swimsuit in a traditional onsen
- Putting your towel in the water
- Speaking loudly
- Using your phone in the bathing area
- Bringing babies wearing diapers into the communal bath
If it’s your first onsen experience, consider visiting one at a hotel or a modern tourist-friendly facility. They usually provide English guidance and are a little easier for beginners.
Many onsen also provide towels and toiletries, so you usually don’t need to bring anything except a change of clothes.
Final Thoughts
Visiting an onsen is one of Japan’s most memorable cultural experiences. Once you understand the basic etiquette, it’s easy to relax and enjoy the peaceful atmosphere.
Take your time, follow the simple rules, and enjoy one of Japan’s most treasured traditions.
