Top 10 Ryokans with Private Onsen in Nagano, Perfect for Soaking in Serenity

I still remember my first trip to Nagano. I went to Tangram Ski Circus, a ski resort in Shinano, and stayed at Barton Hotel. After a long day on the slopes, soaking in an onsen was the perfect way to relax. In Nagano, the combination of hot onsen water, crisp air, and surrounding nature makes the experience unforgettable.

It’s not just the onsens that make Nagano special. The region is famous for its snowy mountains, 80 ski resorts, charming rural villages, and breathtaking landscapes. And among these, you’ll find traditional Japanese inns, known as ryokan, that offer the perfect setting for a peaceful getaway. Some ryokans take the experience even further by offering private onsens, where you can enjoy a relaxing soak in complete privacy.

If you’re planning a trip to Nagano and looking for a unique place to stay, this list is for you. Here are the top 10 ryokans in Nagano with private onsens that promise an unforgettable experience.
