Visiting a Japanese onsen (hot spring) is one of the most unique and relaxing experiences you can enjoy in Japan. But for first-timers, the customs and etiquette can feel intimidating. Don’t worry! This guide will walk you through everything you need to know — from what to bring to how to behave — so you can soak like a local.
🌸 What Is an Onsen?
An onsen is a bath filled with natural hot spring water, often found in mountain regions, traditional ryokan inns, or public bathhouses. The minerals in the water are believed to have health benefits, and the experience is deeply embedded in Japanese culture.
🎒 What to Bring
- A small towel (for washing and modesty)
- A larger towel (to dry off afterward)
- Hair ties (if you have long hair)
- No need for swimsuits — they are not allowed
✅ Most onsen facilities provide towels for rent or sale.
⏺ Step-by-Step: How to Use a Japanese Onsen
1. Remove Your Shoes
Take off your shoes before entering the onsen facility and place them in a locker or shelf.
2. Undress Completely
Enter the changing room, find a locker or basket, and undress fully. Yes — no swimsuits or underwear.
🔸 Onsen bathing is done naked, but no one will stare — it’s totally normal here!
3. Wash Before Entering
Before entering the bath, head to the shower area:
- Sit on the small stool provided
- Wash your entire body and rinse thoroughly
- Use shampoo and soap (provided at most places)
✅ This is the most important rule. Entering the bath without washing is considered very rude.
4. Enter the Bath Slowly
Step in gently, keeping your small towel out of the water. You can place it on your head or the bath’s edge.
5. Relax and Enjoy
Soak quietly and peacefully. Avoid splashing, swimming, or chatting loudly. Most locals enjoy the silence.
6. Dry Off Before Leaving
Use your small towel to pat dry before entering the locker room. Nobody wants puddles on the floor!
❌ Onsen Etiquette & Rules
| ✅ DO | ❌ DON’T |
|---|---|
| Wash before entering | Enter the bath dirty |
| Keep towel out of the water | Put towel into the bath |
| Tie up long hair | Leave hair floating in water |
| Stay quiet | Shout or splash |
| Respect others’ space | Stare or take photos |
❓ Tattoos in Onsen
Many traditional onsens do not allow tattoos, as they are historically associated with crime in Japan.
However, some modern onsens are tattoo-friendly or allow tattoos if covered with a patch. Check in advance.
