Hotels With Spa in Nagano Prefecture, Japan

I changed rooms because my first room smelled strongly like someone's body odor, but the second room also smelled, just less. So I didn't bother to change again. I've never had this issue elsewhere in Japan and I've stayed at a lot of different hotels in Japan, weird... Breakfast has varieties but tasted so so... I was woken up once by people talking in the hallway. Door sound proof isn't great. So if you're a light sleeper, maybe use ear plugs. Good service and amenities otherwise.

Traveling with two others, we booked the West Wing for its convenient location. It's a cabin in the woods, and the scenery is absolutely breathtaking. Waking up in the forest, with few people around and fresh air, felt like having the whole beautiful landscape to ourselves – truly amazing! However, the bathroom facilities are quite old, and showering wasn't very convenient. If you're visiting in winter, definitely book a room with air conditioning; just having heating might not be enough, as it could still get cold. For getting around, the hotel offers a shuttle bus with three routes: one to the outlet mall, one that goes back and forth between the cabins and the main hotel building, and another route that I haven't tried yet (haha). If you're unsure about anything, you can always ask the front desk. I would definitely consider staying here again on my next trip to Karuizawa!

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.

This place is ~5mins walk from Zenkoji temple. neighborhood is peaceful at night. Shoes to be removed outside the accommodation. Rooms are on the 2nd floor so you'll have to carry your luggage up (there's no lift). Room (with window) is huge. You'll have to head downstairs to use the shared toilet and shared onsen (no toilet inside the room). We were only allowed 30mins of onsen time for 2 pax - couples weren't allowed to use the onsen concurrently so we had to go one after another (i'm not sure if the instructions got lost in translation..). Felt very rushed so i didnt really get to enjoy the onsen experience, but overall was nice and clean. Interesting 6.30am tour around the area and within the temple itself, followed by a simple vegetarian breakfast (porridge with omakase-styled sides with miso soup) back at the accommodation. The morning tour lasted from 6.30am - 8.30am. The accommodation provided a fleece blanket to each pax to bring to Zenkoji temple to keep us warm during the morning praying ceremony. We went on 30 Dec and it was SO COLD. Overall interesting experience but accommodation price is pretty steep IMO.

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.

The hotel is brand new. The room is lovely and so spacious! The bed was huge and it was comfortable, we all slept well every night. Staff were courteous and attentive. We really enjoyed our stay here. The hotel location is also perfect, right on old karuizawa ginza street with many food and shopping options nearby during the day. The breakfast options were very limited and the food was the same every day, so I found it a challenge to feed my toddler. Basic food items like cereal and slice bread were not available. The fruit options were also limited and not the most child friendly e.g. pineapple, grapefruit and grapes. Also, the rooms are not made every day but you can request for the staff to clean and make the room. Overall we still had a great stay and hope to visit again soon.

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.

My stay at Hotel Indigo Karuizawa was incredibly comfortable and relaxing. It offered a completely different vibe compared to hotels in central Tokyo. The moment I arrived, I felt like I was on vacation. The design is unique and tasteful, not at all ostentatious, blending beautifully with Karuizawa's natural surroundings. The room was more spacious than I expected, and the balcony offered a great view; waking up and opening the curtains in the morning really brightened my mood. The bedding was very comfortable, and it was quiet at night, leading to excellent sleep quality. The onsen (hot spring) and public areas were also a big plus; after exploring Old Karuizawa, a soak there completely unwound me. The staff provided natural and unobtrusive service, yet they were always there to help when needed. Overall, it's a perfect place to slow down and enjoy the pace of Karuizawa for a night or two. If I come back, this hotel will definitely be my first choice again.

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.
