Hot Springs Hotels in Nagano Prefecture, Japan

Genuinely the favorite hotel I’ve ever stayed at in Japan. The overall level of comfort is exceptional. The room is a good size, everything is well maintained and fully functional, and the baths are fantastic. There are also so many complimentary services and thoughtful little details throughout the hotel that really make the stay special. The food is decent, although not the highlight for me. What I really loved is that this place feels genuinely Japanese and is clearly popular with locals. During our stay, we only saw one or two Western tourists. It doesn’t feel like a typical tourist-oriented hotel at all. If you want to experience a truly authentic Japanese onsen hotel, don’t miss this place. Highly recommended.

It's quite convenient for Tateyama Kurobe, about a ten-minute drive. It offers good value for money, though the room was a bit small, making it difficult to fully open my suitcase. The cleaning was a bit perfunctory; I noticed hair on the walls and in the corner of the bathroom. The hot spring was a nice touch. However, they barely refilled the breakfast items in the last hour.

A very pleasant experience! Very close to the bus terminal! It felt very homey... The beef dinner was plentiful and delicious. The landlady is incredibly spry and speaks excellent English! 👍 She also prepared breakfast at my request (others didn't have it), and the price was very reasonable... very attentive... considering I'm over 50 and traveling alone... excellent service! 👍 The outdoor hot spring is quite 'primitive'... but authentic! Others (hikers) only need to pay 500 yen to enjoy it... If you don't mind the guesthouse feel... you could go again.

Located in the heart of Shibu Onsen, Kokuya is a traditional Japanese inn that has been operating for over 400 years. It's the only inn in the area with its own six different 100% natural hot spring baths, featuring eight public baths and ten rooms with open-air hot springs. It has been passed down through 16 generations. Furthermore, the central area of ​​Shibu Onsen boasts a 1300-year-old hot spring town with nine public onsen (hot spring baths) for hotel guests and residents. The ninth onsen is the largest, featuring a golden bath and a sauna. Next to it is a hot spring shrine and foot bath, right next to Kokuya. Kokuya's hot springs are rich in minerals, beneficial for improving muscle, joint, and skin problems. A free shuttle bus (approximately 3km) takes guests to Jigokudani (Hell Valley) to see snow monkeys and enjoy the hot springs. A free shuttle bus connects to the train station, and freshly cooked onsen eggs (100 yen each) are available at the inn's entrance. The hotel boasts a clean and elegant interior with maze-like corridors and wooden staircases. There are dedicated luggage handlers (three floors in total), creating a perfect setting for a period drama, reminiscent of Yubaba's old house in Spirited Away… The hotel also offers traditional Japanese kaiseki dinners with over nine dishes. Ingredients are freshly delivered from Nagano. The menu changes monthly according to the season. Vegetarian options are also available (please inform us in advance). All guest rooms are designed in a traditional Japanese style, featuring Japanese-style bedding and a bathroom with a sink, TV, safe, refrigerator, towels, and yukata. Ten guest rooms have private outdoor baths. The hotel is surrounded by several temples of varying sizes and different springs nestled in the mountains. The water temperatures of these springs vary, with the highest reaching 56°C. Municipal water supplies are provided to each household. Several bridges connect the two sides of the river in front, including a red-painted bridge that resembles a scene from Spirited Away. I suspect that Miyazaki Toshiro may have drawn inspiration from this place… A very nice hotel and hot springs; the staff are polite and attentive.

This ryokan is the furthest from Main Street. But I love the hospitality from the owner and the authenticity of this place. There is a private onsen available in the ryokan, just need to pre register. They provide access to shibu onsen as well. Recommended to book your dinner with them. Restaurants in shibu onsen either close very early or not open regularly. We missed our dinner, but the owner is kind enough to prepare a simple oyakudon for us. Though this place is at the beginning of forest trail to snow monkey park. But it is close during winter. Just take note.

📍 Hotel Keigetsu 信州昼神温泉郷 日長庵 桂月 @ Hirugami Onsen, Nagano 🇯🇵 We stayed 3D2N from 13 November 2025 at Hotel Keigetsu (日長庵 桂月), and it turned out to be one of the best choices for our Nakasendo trip. The ryokan sits in a peaceful corner of Hirugami Onsen, surrounded by nature and traditional Japanese charm. There is a designated parking area exclusively for guests, accommodating around 15-20 cars of all sizes, making it very convenient for self-drive travellers. We chose a Japanese-style room with a private bathroom, and the highlight was the beautiful wooden bathtub — perfect for a relaxing soak in complete privacy. In the mornings, the view from our room was calm and peaceful, with gentle bird chirping adding to the serene atmosphere. Our stay included breakfast and dinner, and both meals were exceptional. Each dish was beautifully prepared using seasonal ingredients, and the servers were patient and friendly, taking time to explain each course and share stories about local flavours. Their warm hospitality truly enhanced the dining experience. The ryokan is within walking distance to the Morning Market, just about 10 minutes away, making it an enjoyable little morning stroll. There is also a FamilyMart right beside the ryokan, just a short walk away — extremely convenient for drinks, snacks, or last-minute essentials during your stay. The staff also introduced several nearby activities and hiking trails, and the routes are super visitor-friendly, making this ryokan an ideal base for exploring the Nakasendo area. The onsen baths were another highlight — soothing, clean, and filled with Hirugami’s famously smooth, skin-friendly hot spring water. Perfect for unwinding every evening. Overall, Hotel Keigetsu offers excellent food, warm service, relaxing onsen, comfortable rooms, and unbeatable convenience, whether you’re here for onsen relaxation or the Nakasendo trail. Highly recommended for a peaceful, authentic, and memorable ryokan stay in Nagano. ♨️🍁🌿✨

I had a large tatami room with side sitting area and sink as well as an ante-room. I had three delicious Japanese meals at the ryokan that were served with polite elegance. The two in-house onsen baths were a joy to use after a day of skiing. The staff was knowledgeable about how to get around by the buses and suggested the best restaurants for days that I did not eat at the ryokan. Senshinkan Matsuya was situated in the center of.Shibu Onsen town next to three of the public onsen. I could not ask for a better stay!

Although the room rate isn't cheap, I think overall it's a hotel with excellent value for money. Firstly, the hotel environment itself is superb. It's spacious with lots of greenery, including a lake, trees, lawns, and small villas, making it very pleasant for a stroll. Secondly, there are hot springs and a shuttle service. Plus, right next to the hotel is a beautiful and very large outlet mall, offering convenient dining options. The shuttle runs in a loop, taking guests to JR Karuizawa Station and the outlets. Even though it's not a far walk to the outlets anyway. The hot springs ♨️ are free for hotel guests and include outdoor baths and a sauna. The hotel also has a golf course, which we didn't visit, but we saw staff assisting guests with their golf clubs in the morning. The only downside is that the hotel is quite large, and some guest rooms are a bit of a walk from the front desk. The West Wing is closer to the shopping plaza, while the East Wing is closer to the ski resort. It seems the West and East Wings are booked separately. The rooms are not small, and the window views are very pleasant. All in all, it's a hotel I would happily choose to stay at again.

We spent 2 nights in Prince after first 2 nights in Kusatsu onsen town. The hotel looked underwhelming on arrival and the front office service was efficient but cursory compared to the warm hospitality we had in the ryokan stay. It was low season and hotel was very quiet and had a ”cold” atmosphere. I was further disappointed when we were shown our room which was on the lowest floor with a simple garden view. On requesting the check-in staff for a change of room on higher floor and a more scenic view, I was told there is an upgrade charge, which I accepted. The new room was the same size and configuration but on a higher floor with a nice view of Mt Asama. While I was happy to pay the fee, I can't help but compare their practice with all the hotels that I have stayed in all these years, where room changes were complimentary so long as the room type remains the same. Nevertheless, the hotel's facilities delighted me immensely and I enjoyed the overall experience. The highlight of the hotel stay was the fantastic view of Asama in a high ceiling dining room with full glass window. We were able to have different table seatings for both morning breakfast as the hotel occupancy was low, which gave us different perspectives of the scenery. The other highlight of the hotel is the onsen facility which is located in a separate building on higher ground, accessible via a self service automated tram. Aside from Asama view in the outdoor onsens, there is a common lounge which has equally awesome view of Asama. We enjoyed our time soaking in onsen and resting in the lounge. Was I would go back to Prince Asama and experience the scenery during a different season!

We really enjoyed our week long stay at Hoshikawakan in Jan 2026. We have been driving around Hakuba for 4 weeks to visit various ski resorts and spent our last week at Hoshikawakan to visit Shiga Kogen. The room was spacious and clean with a small toilet like most Japanese hotels but there was a large public onsen and 2 smaller private onsens that can be reserved once each day for 30mins so you could always take your shower in the onsens like the locals do especially later at night about 10-11pm where I was the only one in the public onsen. The hotel had a lovely buffet breakfast spread with local soba, Japnese curry, cold minced sashimi fish, grill fish station, fried eggs station that will keep you adequately fed for the day's ski trip - it even has a hot drink station with free oden daily at 3-5.30pm which we enjoyed as a snack after a hard day of skiiing. The service was excellent too with the staff helpfully arranging to ship our ski equipment directly to Hanade Airport, daily clearing of snow off the carpark and new towels provided daily. The location in Yudanaka is great too especially if you drive as it is between Shiga Kogen (25-35mins drive) and Kita Shiga Kogen (15-20mins drive) with many attractions like Shibu Onsen, Yudanaka Brewery and Snow Monkey Park within 10-15 drive. There were also ample dinner options nearby within 10-15 mins walk but you may need to try and make reservations by walking in on your first night. The only downside was that the WiFi network is poor and patchy when overloaded by a lot of guests over the weekend but otherwise it was good.
