If you’re visiting the Chita Peninsula, trying out a Japanese onsen (hot spring) is something you shouldn’t miss.
It’s not only a great way to warm up and relax, but also a wonderful chance to enjoy Japanese culture and beautiful scenery.
Many onsen in Chita are located near the sea, and the open-air baths (rotenburo) with views of the ocean or sunset are simply amazing.
However, Japanese onsen come with a unique set of rules and etiquette, which may be confusing if you’re not familiar with them.
You might wonder things like: “Do I really have to bathe naked?” or “Is it true I have to wash before entering the bath?”
To help you feel more comfortable, we’ve put together a list of useful tips for first-time onsen visitors.
We hope this guide helps you enjoy your onsen experience smoothly and with confidence.
Basic Rules to Know Before Entering an Onsen
Let’s go over the basic etiquette step by step.
It may feel unfamiliar at first, but once you understand the rules, it becomes part of the fun and charm of Japanese culture.
You’re expected to bathe completely naked
In most Japanese onsen, wearing swimwear or underwear is not allowed.
Everyone bathes naked, and while it might feel awkward at first, you’ll quickly get used to it—everyone is in the same situation.
Note: Some onsen allow swimwear, but they are the exception. Most require full nudity.
Don’t bring your towel into the bath
You can bring a small towel with you to use for washing, but do not put it into the water.
Many people place it on their head or leave it on the side of the tub.
Wash your body before entering the bath
It’s important to thoroughly wash and rinse your body before soaking in the bath.
Use soap and shampoo at the shower area to make sure you’re clean.
There are also small buckets for rinsing (called kakeyu), but they are not a substitute—proper washing is expected.
Keep your hair out of the water
If you have long hair, tie it up with a hair tie or clip so it doesn’t touch the water.
Hair in the bath can make other bathers uncomfortable.
Keep your voice down
Onsen are places for quiet relaxation.
It’s okay to chat with your friends, but please do so in a calm, low voice to respect others’ peaceful time.
No photography or filming allowed
Cameras and smartphones are strictly prohibited in most onsen areas.
This is to protect the privacy of all guests—do not take photos or videos in the changing room or bathing area.
Be aware of tattoo restrictions
In Japan, tattoos can still be associated with criminal groups, so some onsen may not allow guests with visible tattoos.
However, more places are becoming flexible—some allow tattoos if they’re covered with a seal or patch, so check in advance when possible.
Dry off before entering the changing area
After soaking, use your towel to dry off completely inside the bathing area.
Walking into the changing room soaking wet is considered bad manners.
Many onsen also have saunas and cold baths
At many facilities, you’ll find saunas and cold-water baths in addition to the hot spring.
The “sauna → cold bath → rest” routine is popular for improving circulation and refreshing both body and mind.
Take it at your own pace—there’s no need to push yourself.
Most baths are gender-separated, but private baths are available
Japanese onsen are usually separated by gender, so couples and families cannot bathe together.
However, some places offer private or family baths (kashikiri/family onsen) where everyone can enjoy together.
These often require a reservation.
Don’t stay in the hot water too long—start with 5–10 minutes
As a general rule, start with 5 to 10 minutes, especially if it’s your first time.
Take breaks in between to cool down, stay hydrated, and avoid getting lightheaded or dizzy.
In Closing
Japanese onsen can be incredibly soothing and enjoyable—as long as you follow a few basic rules.
It’s a special part of Japanese culture that lets you relax both your body and mind.
Even if it’s your first time, this guide will help you feel prepared.
Enjoy the experience, and don’t hesitate to give Japanese onsen a try during your visit to the Chita Peninsula!
