Hotels With Spa 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!

I brought my own snowboard to Karuizawa. It's a 70-minute Shinkansen ride from Tokyo Station to JR Karuizawa Station. The Shinkansen luggage racks have straps to secure snowboards. After exiting the station, head to the hotel service center (open until 7 PM) located on the far right of the 7/11 convenience store at the South Exit (Pic 7). You can drop off your luggage there and then explore the Plaza unencumbered. Take the brown hotel shuttle bus to B21, where The Prince is located, every hour on the hour and half-hour. Your luggage will already be in your room, but snowboards are not allowed inside. Each day, I'd take my own snowboard on the brown bus to the gondola at the East Building. You can buy ski passes and rent equipment there. Ski pass prices are shown in Pic 6. Only guests staying in the East Building can use the hotel's lockers for ski equipment. The West Building also has a gondola, but it requires a short walk. You can't enter the hotel wearing ski boots, but the Makibi restaurant seems to be an exception. After skiing, take the green bus back to the hotel. Of the two onsen, Hongye Bisen has newer facilities and better views from the outdoor bath. All Prince Hotel restaurants require reservations made via QR code. Pics 4 and 5 show the breakfast at the main building, which is high quality and delicious. From 10 AM to 8 PM, you can enjoy unlimited soft drinks in the bar area. Finally, use the luggage delivery service when checking out. I think The Prince offers the best value for money.

I stayed at this hotel for one night, and overall, it was quite a pleasant experience. I really liked my room — it was clean, modern, and comfortable. The only thing that surprised me was that the window to the balcony didn’t open, though I suppose it was designed that way. The onsen was absolutely wonderful — spacious, relaxing, and with a beautiful view of a mountain river. Definitely one of the highlights of my stay. The hotel also offers many different areas for leisure and entertainment. You can play table tennis, relax in cozy rest zones, visit small cafés and shops — there’s a lot to explore without even leaving the building. Both breakfast and dinner were delicious, with a wide variety of food to choose from. However, due to the number of guests, it was a bit challenging for the staff to manage everything smoothly. On two occasions, someone almost took my table, even though I had already placed the reservation card on it to show it was taken. That said, the staff overall were very pleasant, friendly, and helpful, and I appreciated their attitude throughout my stay. This hotel is clearly family-oriented, with many families staying with young children. There are rooms with child-friendly designs and dedicated play areas, so if you’re looking for a quiet, adult-only atmosphere, this might not be the best fit. That said, I genuinely enjoyed my stay and would consider coming back.

This is a popular hotel that is always fully booked. The breakfast buffet has a wide variety of dishes and is delicious. And although the bath isn't particularly large, I love the panoramic view from the top floor!

Very decent hotel with good services from the hotel staff. Come with onsen & spa facilities as well as large size rooms and bathrooms. Less than 10 minutes car ride from the Karuizawa station, ski centre and the Prince Shopping Plaza. Hotel also provides free shuttle bus services through and forth to the Karuizawa station which conveniently accessible to the ski centre (free shuttle bus services outside the South exit of the Karuizawa station) and the Prince Shopping Plaza (stone throw from Karuizawa station).

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!

I booked two rooms for two nights, but due to a system glitch, one of the rooms wasn't successfully booked. Trip.com customer service then recommended another hotel. However, the next day when we arrived at the new hotel, we still couldn't check in. All payments for both rooms had been made by 10:30 AM, so they should have been reserved for us. Yet, the hotel again cited a system error and said our rooms hadn't been held. They then told us to return to the first hotel, and it was already around 11 PM at that point. I was utterly frustrated by the whole situation. Despite all this, Trip.com's customer service was very responsive and helpful, thumbs up to them.

This was my first time in Karuizawa, and I booked this hotel without knowing anything about it. To my surprise, it felt more luxurious than I expected, especially since it was a family trip abroad that we planned about a year ago, so the price wasn't overly expensive either. The hotel's design and the breakfast, which exceeded my expectations in terms of quality, made me want to stay here again if I visit Karuizawa next summer!

Onyado was a joy to stay in. Im sad I have to leave the hotel. It is so thoughtful with all the kind amenities! I really love that shoes are not allowed indoors. The breakfast spread is also with good variety and extremely delicious Japanese style breakfast. The rooms itself are spacious compared to the ones in Tokyo. I was able to enjoy the tatami floors! The onsen is not large but is reasonable and never too crowded. The ambiance is also nice and it comes with a sauna. The tv contains congestion information so you can check it in advance! Everything to love about this hotel, I think it’s one of the best I’ve stayed in Japan. Really super recommend. would love to stay here again if I can.
