First time? You'll be fine. A gentle guide to bathing and its etiquette.
An onsen (natural hot spring) or a sento (neighborhood bathhouse) is a uniquely Japanese place to unwind. It's also where travelers hesitate most — but once you know the flow, you'll be at ease. The core idea is simple: clean yourself first, then share the bath with everyone.
Before you go in
Baths are separated by gender. You tell them apart by the color and characters on the noren curtain at the entrance. Often red tends to be women's and blue men's, but always check the sign. Undress in the changing room and leave your large towel there — you bring only a small towel inside.
First, rinse off
Before entering the tub, wash at the shower stations. Use a shower or a bucket to rinse your body first. Many people wash thoroughly with soap here. Cleaning yourself before you soak is an important courtesy.
In the tub
The tub is for soaking. Don't put your towel in the water — rest it on your head or the edge. If your hair is long, tie it up so it stays out of the water. Don't swim or speak loudly; just warm up quietly.
About tattoos
Some facilities may ask guests with tattoos to refrain from bathing. Others let you cover a small one with a waterproof patch, welcome tattoos openly, or offer private baths. If you're unsure, checking with the facility in advance puts your mind at ease.
After your bath
When you get out, pat yourself dry a little before stepping into the changing room. Drink some water and rest. A cool drink afterward, or the breeze on your warm skin, is a reward all its own.
More than the fine rules, it's the care for those around you and the simple pleasure of getting warm that matter most. That's the best etiquette there is.
