Nozawa Onsen has been a beloved mountain retreat for centuries. Long before it gained international fame for its powdery slopes, it was a haven for travellers from Tokyo, drawn by the healing power of its natural hot springs. This quaint mountain village is so abundant with hot springs or onsens that its name, Nozawa Onsen, literally means “Hot Springs in the Wilderness”.
Today, you can still feel the essence of Japan’s ancient traditions as you stroll through the charming streets and admire the Edo-era architecture all around. Nozawa Onsen is a place where you can enjoy adventure, culture, gastronomy, and relaxation all together. But if what you’re really after is the amazing hot spring experience, then allow us to help you out with this all-in-one guide to onsen-hopping in Nozawa Onsen, Japan.
A Dip into History and Onsen Etiquette
Soaking in an onsen is more than just a relaxing bath; it’s a cultural experience deeply rooted in Japanese history. Samurais and soldiers used to bathe in onsens to heal their wounds after battle. The waters in the hot springs were considered sacred and were believed to have healing properties.
So before you head to your first onsen, remember the golden rule: Respect the local customs. Here they are in more detail:
- Bring your modesty (and a small towel): Onsens are traditionally enjoyed in the nude, so be prepared to share the room with others. You can bring your own towel, soap, and shampoo, or pick up an onsen basket at the local shops.
- Shoes off, please: Once you enter the onsen, slip off your shoes and clothes and place them in the designated locker area. It’s important to take them off before stepping onto the raised wooden area.
- Wash before you soak: It’s crucial to wash your body thoroughly with soap before entering the onsen. This ensures the water stays clean for everyone. You can even sit by the tap and pour some hot spring water over yourself before stepping into the bath.
- No drinking or eating: Enjoy a delicious meal or a refreshing drink before or after your onsen experience, but leave the food and beverages outside the bath.
- Dry yourself after: Use a small towel to dry yourself after your soak before stepping on to the wood.
- Follow the locals: If you’re unsure about something, just observe the locals. They are incredibly welcoming and will be happy to guide you.
The Shu-in Stamp Trail
Nozawa Onsen is a wonderland of 13 public onsens (and more private ones), each with its unique charm and therapeutic benefits. To experience the full glory of Nozawa Onsen’s hot springs, embark on the Shu-in Stamp Trail! This scavenger hunt-like activity lets you discover each onsen at your own pace, collecting a unique stamp at each one.
We recommend purchasing a Shu-in-cho stamp booklet from the Hot Spring Sightseeing Information Center or the Ryokan Society before starting your onsen-crawl. Each onsen has a special wooden stand outside, featuring a unique design and a number that matches a page in your stamp booklet. When you visit an onsen, locate the corresponding page in the booklet. Then, use the wooden stick attached to the stand to rub over the page, revealing a beautiful imprint of the onsen’s “stamp.”
Collect at least 10 of these unique stamps, show it to Nozawa Onsen’s tourism association and you’ll be rewarded with a special Nozawa Onsen bath towel as a memento of your hot spring adventure!
The 13 Onsens on the Shu-in Stamp Trail
All of these onsens are free to the public. However, they do accept donations to help maintain the establishments.
1. O-yu Onsen
The heart and soul of Nozawa Onsen, O-yu is a grand Edo-style bathhouse right on the main street, Oyu-dori. This onsen is a popular spot for locals and visitors alike, so if you want to soak in a lively atmosphere, this is the place for you. However, if you prefer it to be more quiet, avoid visiting during peak hours in the afternoon.
The onsen water is fed from a simple sulfur spring, known for its ability to alleviate rheumatism, gastrointestinal issues, and even gynaecological ailments. Be prepared for a hotter soak, as O-yu’s water temperature can reach close to 60°C (140°F)!

Its unique greenish water, rich in minerals, is believed to have particularly healing properties. Taki-no-yu’s water, sourced from a sulfur spring with calcium sodium-chloride, can reach a scorching 78°C (172°F)!
