Onsen Etiquette Basics: Learn the Steps and Never Be Lost

For people visiting a Japanese onsen for the first time, the biggest worry is probably, “How am I supposed to bathe?” Where do you undress? Where do you put your towel? What order should you wash in? — entering without knowing can be confusing.
But the core of onsen etiquette is very simple. Keep the shared bath clean, and make sure others can enjoy it quietly and comfortably. That is all. Every detailed rule flows naturally from those two ideas. In this article, we’ll walk through the process from before you enter to when you leave.
Basic bathing flow
First, understand the overall order so you won’t get lost.
| Step | What to do | Why |
|---|---|---|
| 1 | Undress in the changing room | Only a small towel goes into the bathing area |
| 2 | Pour hot water over your body first | Helps prevent sudden blood pressure changes from temperature shock |
| 3 | Wash yourself while seated at the washing area | Keeps the shared bath clean |
| 4 | Soak in the tub | Do not put towels or hair into the water |
| 5 | Wipe off before returning to the changing room | Avoids wetting the floor and changing room |
Undress in the changing room
At an onsen, you undress in the changing room before entering the bathing area. Leave large bath towels and your change of clothes there, and only take a small towel into the bath area. It helps to remember: “The changing room is for preparing, the bathing area is for bathing.”
Do not enter the tub without washing first
This is the most important rule. The biggest etiquette violation at an onsen is getting into the tub without washing your body first. In some countries, it is normal to bathe without showering, but in Japan’s shared baths, this is something to avoid. Once you enter the bathing area, head to the washing stations first.
Before that, pour hot water over your body. Start from your feet and move upward to help your body adjust to the temperature. If you enter very hot water all at once, your blood pressure can change suddenly, causing dizziness or overheating. Japan’s Consumer Affairs Agency also recommends avoiding sudden temperature changes and adjusting your body with hot water first. For more on washing before bathing, see How to Wash Before the Tub.
Etiquette in the tub
In the tub, do not put towels in the water. This helps keep the bath clean. Place your towel on your head or on the edge of the tub. If you have long hair, tie it up so it does not touch the water.
The tub is also a place to be quiet. Avoid loud conversations or swimming-like behavior. In Japanese onsens, the people around you are also quietly enjoying their own time. For conversation etiquette, see How to Keep Conversation Quiet at an Onsen.
Photography, tattoos, and changing-room cautions
Because the bathing area is a space where people are nude, bringing in smartphones or cameras and taking photos is prohibited. This is to protect privacy, and some facilities also ban photography in the changing room (Onsen Photo Etiquette).
If you have tattoos, some facilities will refuse entry, while others may allow you with cover stickers or a private bath. Checking in advance is safest (Tattoos and Onsen: What to Check Before Booking).
When leaving, wipe your body lightly before going back to the changing room. This is a courtesy to avoid wetting the floor and changing room. If you are unsure about the detailed bathing process, see Basic Steps from the Changing Room to the Tub.

Summary
Onsen etiquette is based on two principles: keep the shared bath clean, and let others enjoy it quietly. If you remember the order undress → pour hot water → wash → soak → wipe off, you won’t get lost even on your first visit. It is not about complicated rules; it is simply consideration for a shared space, and once you see it that way, it comes naturally.
