Hot Springs Hotels in Nagano Prefecture, Japan

Absolutely stunning! The hotel itself is a resort. It's beautiful, clean, and the service is excellent. We rented bicycles at the hotel and cycled to Old Karuizawa, the wealthy villa district, and a park with a pond (I can't recall the name). After that, we hit up the outlet mall, which is super close by. So many brands and great deals – it was a shopping paradise! They even have my favorite coffee shop and a sashimi spot there. We had such a blast, I definitely want to go back in the autumn.

The room was incredibly spacious, offering exceptional value for the price. The hotel maintains a peaceful and quiet atmosphere, which I truly appreciated. While the furniture and carpets show some slight signs of age, the overall comfort remains high. I was impressed by their Zero Waste policy; instead of plastic bottles in the room, they provide glassware and a convenient water dispenser located right by the elevator. Please note that for a two-night stay, there is no housekeeping service, which aligns with their eco-friendly initiative. The amenities were comprehensive, and the service was outstanding—truly upholding the high standards of the Mercure brand. Parking is plentiful and hassle-free. Lastly, the view is a hidden gem; on a clear day, you get an unobstructed, breathtaking panorama of the mountain range without any buildings blocking the sight. I highly recommend it for a relaxing getaway!

The hotel is very close to the station, with a 7/11 downstairs. The area is lively, a hub for restaurants and malls, yet surprisingly quiet – a peaceful oasis amidst the bustle. The room size is generous for a Japanese hotel, and the facilities are modern and well-maintained. On the 11th floor, there's an open-air onsen with complimentary Yakult and cold drinks, and free ramen is offered in the evenings. I had a very satisfying stay and highly recommend it.

The room was spacious and clean. Located by the lake, it was convenient for walks. The hotel's large public bath and the private onsen in the room were very relaxing. The kaiseki dinner was also delicious. The flavors were subtly delightful, which I really enjoyed. Overall, a wonderful travel experience.

This is our first time to ski Japan.  This hotel was located perfectly with great access to some super beginning facilities.  Good enough about skiing, the hotel is perfect and the staff is amazing. The food and amenities are excellent. We had a private hot spring every evening really added to the enjoyment.  My wife and I and eight year-old daughter had a great time  you so much for the great experience and all the hospitality  Perfect Stay. 100%!!!

The hotel looks old and isn't particularly striking from the street. However, the Japanese are incredibly meticulous with cleaning, so it's impeccably clean inside. The location is also super convenient (there's a great ramen place in the next building). You'll even find some retro features, like a two-handle faucet and an old TV – very authentic. My only minor complaint is that I couldn't get the air conditioning to cool, only to heat.

This is the best choice if the kids want to ski and the adults want a place to wander around! We can relax in the hot springs, stroll around the outlets, and the kids can ski to their hearts' content. We can also drive to the Karuizawa shopping street for a leisurely walk. It's an effortless trip, perfect!

The location is great, just have to cross a bridge from the train station. And there were many food options around the train station area. The room was clean and just the right size for a single traveller. There was even a microwave oven in the room! The hotel is quite strict on its check in timings, its not really a downside, just a heads up for people who might try their luck for early check ins.

We stayed for 3 nights with meals included. The buffet offered slight variations each day, especially with the tempura and sushi ingredients, soups, and cake selections. Everything was delicious, and we never got bored. Since we opted out of daily cleaning for our multi-night stay, we received a 1000 yen voucher for the hotel shop each time, which was a nice bonus during the busy season. The hotel layout was compact and well-organized. It was easy to get around from the ski locker to the public bath, restaurant, and front desk, making for a very comfortable stay. The only minor issue was the towels. We only received exactly enough bath and face towels for the number of guests. If you use one as a hand towel, you quickly run out, especially on a multi-night stay. I wish they had provided a few extra.

I stayed in a twin room on September 1, 2025. It was very busy with tourists, and the front desk was congested. The food buffet was more about quantity than quality, so I ended up overeating. I could hear the movement of guests on the floor above me and the sound of water leaking from the drain pipes. Water was leaking from the floor of the unit bathroom. The toilet was child-sized, and the hot water was a little hot, but I would definitely stay here again.
