Japan’s hot springs, or onsen, are a beloved part of its culture and a must-experience for travelers. Whether you’re seeking relaxation after a long day of sightseeing or a traditional cultural experience, visiting an onsen offers both. But to fully enjoy this unique Japanese tradition, it’s important to understand the etiquette and know the best spots to visit. In this guide, we’ll walk you through essential onsen manners and introduce some of the top hot springs across Japan.
What is an Onsen?
An onsen is a natural hot spring bath, often located in scenic areas rich with volcanic activity. The mineral-rich waters are said to have therapeutic properties, promoting relaxation and health benefits. Onsen can be found indoors or outdoors (rotenburo), with some offering stunning views of mountains, forests, or even the ocean.
Onsen Etiquette: What You Need to Know Before You Go
Experiencing an onsen is not just about soaking in hot water—it’s also about respecting customs that have been followed for centuries.
1. Wash Thoroughly Before Entering the Bath
Cleanliness is paramount. Before stepping into the communal bath, use the provided showers or wash stations to thoroughly clean your body. This ensures the water remains clean for everyone.
2. No Swimsuits Allowed
Onsens are traditionally enjoyed naked. Swimwear is generally prohibited, so prepare to bathe without clothing. Most facilities have separate areas for men and women.
3. Towels are for Outside the Bath Only
Use your small towel to cover yourself while walking to the bath but do not bring it into the water. Instead, leave it on the side or place it on your head.
4. Avoid Splashing or Swimming
Onsens are for relaxing, not for vigorous activity. Keep noise levels down and respect other bathers’ peace.
5. Be Mindful of Tattoos
Some onsens ban guests with tattoos due to their association with the yakuza (Japanese organized crime). However, many places are becoming more tattoo-friendly or offer private baths.
6. Hydrate After Your Bath
Soaking in hot water can dehydrate you. Drink water afterward to stay refreshed.
