3. Types of Onsen Experiences

  • Rotenburo (Outdoor Baths): Soaking in an outdoor bath with a view of nature is one of the most popular onsen experiences. Many ryokans offer rotenburo with scenic views of mountains, rivers, or forests.

  • Ryokan Onsen: Traditional inns often feature private or shared onsen baths. Staying at a ryokan provides an authentic Japanese experience, complete with tatami rooms and kaiseki (multi-course) meals.

  • Public Onsen: Many onsen towns offer public baths where visitors can experience the local culture. These are often cheaper than ryokan stays and provide an opportunity to interact with locals.

  • Mixed-Gender Onsen: While most onsen are separated by gender, some onsen allow mixed-gender bathing, though this is becoming less common. Make sure to check before visiting if you're interested in this experience.


4. Best Time to Visit Onsen

The onsen experience changes with the seasons, and each season offers its own unique charm.


  • Winter (December to February): Winter is perhaps the most magical time to visit onsen, especially those with rotenburo. Soaking in a hot spring while surrounded by snow is an unforgettable experience. Winter is also the peak season for onsen, so early reservations are recommended.

  • Summer (June to August): Although summer may not seem like the best time for hot baths, onsen in mountainous areas offer a refreshing escape from the heat. Plus, after hiking or exploring, a soak in the onsen is perfect for tired muscles.


  • Autumn (September to November): Autumn is one of the best times to visit onsen, thanks to the beautiful fall foliage. The combination of vibrant leaves and hot springs creates a stunning and serene atmosphere.

5. Onsen Etiquette for First-Time Visitors

Experiencing onsen is a great way to immerse yourself in Japanese culture, but there are some key points of etiquette to be aware of:


  • Shower First: Always wash and rinse your body thoroughly before entering the onsen.

  • Towels: Bring a small towel into the bath area, but don’t let it touch the water. Place it on your head or leave it outside the bath.

  • No Swimming: Onsen baths are for soaking, not swimming. Be mindful of others and avoid splashing.

  • Tattoos: Some onsen have restrictions on visible tattoos, so check ahead or consider onsen that allows tattoos.


6. Where to Stay

For the full onsen experience, staying at a ryokan is highly recommended. Ryokan inns offer not only access to the onsen but also traditional meals and beautiful tatami mat rooms. Many onsen towns also have budget-friendly hotels or hostels for those seeking a less expensive option.


7. Food to Try in Onsen Towns

No onsen trip is complete without indulging in local cuisine. Here are some foods you should try during your onsen getaway:

  • Onsen Tamago: A soft-boiled egg cooked in the hot springs, with a creamy, delicate texture.
