This was our second stay. Since our third son (our beloved dog) joined our family five years ago, we only choose Accommodations where we can stay together, so we’ve stayed at many pet-friendly places around the Kanto area. With new Accommodations opening all the time, there are only a few we’ve ever revisited—but this one is exceptionally satisfying, so we returned during the Obon holiday period. With pet-friendly Accommodations, there’s often something you have to compromise on, but this place is almost perfect. The balcony of our guest Room had an open-air Onsen bath, a sauna, a cold plunge bath, and a relaxation area with a shower—plus an open-air bath for dogs. Inside the Room, there was a theater room with two massage chairs and a dining room where you can enjoy meals in your Room. The French cuisine served there is truly delicious. Recently, more and more Accommodations have excellent Facilities, but I don’t know any other place where you can enjoy food of this quality in your Room with your dog. Once again, everything was absolutely delicious. If you’re looking for the best Accommodation to stay with your dog, I highly recommend giving this place a try.

After enjoying canoeing in Kushiro, we arrived and were immediately impressed by the spacious, beautiful entrance. The lobby, centered around an irori hearth, felt wonderfully open and soothing with its charming design. Every member of the staff was truly welcoming, making our stay relaxing and comfortable. The milk soft-serve and milk were rich and flavorful, and the morning daifuku and ozenzai were also delicious. This is our number one Accommodation we’d love to visit again.

My parents and I had a very comfortable stay. They said they would like to come again, which made me happy as the one who gave them this trip as a gift. All the staff were very courteous and attentive to every detail. We relaxed with coffee in our Room, warmed up to the core in the free-flowing Onsen, and slept soundly. Every dish was delicious. The acqua pazza, in particular, was the best I have ever had.

This was our first stay here. Although we originally planned to come by car and had to switch to the train at short notice, you still picked us up at the scheduled time. The Room was just the right size for two people, and we also appreciated how clean it was. There were plenty of amenities and many complimentary drinks, so we were able to relax and take our time. Each dish was carefully prepared, and combined with dining in a private room, it felt truly luxurious. Everything tasted excellent. We enjoyed the chocolates served at the end of dinner during our morning coffee time. The late-night snack was also refined and delicious. The bath required adjusting the temperature, but that actually allowed us to set it exactly how we liked it, which was great. As it is a sulfur hot spring, there was a faint scent that lingered after bathing, but it wasn’t too strong—just enough to feel its benefits. Breakfast was also delicious: kamameshi cooked with dashi with slightly indulgent side dishes, all thoughtfully prepared. Overall, we were truly satisfied with our stay.

We stayed for 3 days and 2 nights. The Facilities, the staff’s atmosphere, and the meals were all excellent. It was clear that each staff member truly loves dogs. We would definitely like to stay again.

This was a Hotel I definitely want to stay at again! Not only were the amenities and play area great, but the private family bath was surprisingly easy to use when we wanted, and we were able to relax and enjoy a bath together as a family. Free laundry and drying were also available, which was a huge help—especially with our 2-year-old, when we ran out of spare clothes and started to panic. Meals were buffet-style, so we ended up eating quite a lot and couldn’t make it for late-night snacks, which was a shame—but next time I’ll plan better (haha). Just one thing: the kids’ meals didn’t change much between breakfast and dinner, so our child got a bit bored. It would have been nice to have a little more variety.

Our family of four, ranging in age from our 60s to 90s, enjoyed a relaxed and unhurried stay. We were very satisfied with the Onsen, the meals, and the Room, but above all, the warm hospitality of the staff truly put us at ease. The calm atmosphere of Owani Onsen was wonderful, and we would love to return once more before the snowy season begins.

I chose this Accommodation for my boyfriend’s birthday trip. It was my first stay here, and it far exceeded my expectations. Above all, the staff’s service was truly outstanding, and I was moved by every thoughtful gesture. The property has the charming presence of a grand traditional Japanese house, and the garden is beautifully maintained. We enjoyed a luxurious time dining at a relaxed pace while looking out over the garden. The basashi (horse sashimi) in particular was the best I’ve ever had—absolutely unforgettable. The Room was spacious and spotless, very comfortable, and the view from the window was wonderful. The building also has delightful surprises and playful touches that even first-time guests can enjoy, which kept me excited throughout our stay. They also offer an excellent selection of sake, so I especially recommend this Accommodation to sake lovers. It was one of the most memorable places I’ve ever stayed—completely satisfying in every way. I will definitely return.

This was an Accommodation I’d wanted to visit for a long time. I was hoping for the riverside bath and a starry sky, but due to the river running high and cloudy weather, it didn’t happen. Still, the Accommodation was wonderful, so I was completely satisfied. At check-in, we were served delicious homemade sweets: hanamame beans with shiratama in kinako and kuromitsu. The proprietress and staff were very pleasant, and the hot spring bath—fed directly from the source—overflowed generously and felt amazing. The meals were beautifully presented using local ingredients, and we were happily full. The Room was clean and relaxing, with the sound of the river (it was quite loud this time because of the high water, but I’m sure it’s usually soothing). It was also lovely to see small wildflowers displayed throughout. It’s an Accommodation I’d love to stay at again and again. We will definitely return.

From the moment I was picked up, the staff made a great impression, and as soon as I stepped into the Hotel, I was soothed by a wonderful aroma scent. I was shown to a private Room to check in. The Room had a simple design and was very comfortable to stay in. I also enjoyed choosing my favorite scent with the aroma diffuser in the Room. This time I joined the 1-night, 2-day fasting course. Since it wasn’t a water-only fast, I had carrot juice, homemade umeboshi (pickled plum), bancha tea, and more for dinner and again the next morning. After checkout, they treated me to rice porridge, miso soup, handmade umeboshi, hana ingen beans (runner beans), and bancha tea—everything was very satisfying. Personally, the hana ingen beans slowly simmered over two days with beet sugar were so delicious that I couldn’t help asking if they were available for purchase. After check-in, I also received a brown-rice onigiri with umeboshi, which I enjoyed on my long-distance bus ride home. There is no TV in the Room, but Wi‑Fi is available so you can use your smartphone. However, since it was such a good opportunity, I tried not to use my phone during my stay as much as possible. Time flew by as I read health magazines in the lounge with herbal tea in hand; opened the window in my guest room to read my own book while listening to birdsong; and reviewed personal finances that had been put off due to everyday busyness. From the Onsen bath area in the morning, you can see Mt. Asama—the view was truly wonderful. If there’s one thing to mention: since exercise is part of my routine personally, having showers in every Room would have made it even more comfortable by allowing me to rinse off quickly after working out. Other than that minor point, everything exceeded expectations—the staff were lovely throughout—and it was a stay I would definitely like to repeat.

The room offers stunning views of the city and lake. The hotel restaurant serves authentic local cuisine, and everything was delicious.

As a car and racing enthusiast, I love the details of this Hotel. The weather wasn’t great this time, but I was glad I could still see Mt. Fuji from my Room. I always choose the “view assigned by the Hotel,” and you can enjoy it no matter which side you get. This time again, we had dinner at Robata Oyama, and it was delicious—we were very satisfied. I also really like the breakfast.

I’d been wanting to visit for a long time, and I was finally able to stay this time. Unfortunately, because of the rain there was no goat welcome, but I enjoyed a champagne welcome drink in the lobby and headed to my Room feeling excited. The Room was very spacious and impeccably clean, so I felt comfortable throughout my stay. The fog was quite heavy so the view wasn’t very clear, but I was told you can see Mt. Fuji on a clear day. I also really appreciated the complimentary free-flow drinks in the refrigerator. I requested refills of various items such as half bottles of champagne and water. The bath is an Onsen, with a faint sulfur scent and just the right temperature. It wasn’t an open-air bath, but opening the window made it feel wonderfully airy. It was also my first time staying in a Room with a sauna (with cold plunge), and it was a great experience—I worked up a good sweat and truly enjoyed it. Dinner was thoughtfully prepared across every dish and absolutely delicious! The wine pairing was excellent as well, and I had a wonderful time until the very end. For a late-night snack, we were served conger eel sushi—far beyond what you’d expect for “late-night,” truly authentic. I enjoyed it with another refill of champagne. For breakfast we chose in-Room dining; the pork miso soup was especially delicious, and being able to have seconds left me completely satisfied. Above all, the staff were courteous with just the right sense of distance while still being incredibly attentive—checking on drink replenishments in our Room and more—which made for an excellent stay. I would love to return for another stay. Thank you very much.

I had a wonderfully relaxing stay at a comfortable pace. It was quiet and spotless throughout, and the Onsen was incredibly open and wonderful. Every meal was deeply delicious. The staff were also very pleasant and welcoming. I feel as if both my body and mind have been refreshed. I can hardly believe how reasonably priced it is. Thank you very much. I will definitely return.

I stayed here after relatives in Shonai recommended it as an Accommodation with excellent food, and it exceeded my expectations. From appetizers to dessert, everything was carefully prepared—making the most of the ingredients with creative touches—and the portions were generous. Every dish was delicious, and I left completely satisfied. Breakfast was just as impressive as dinner, with a wide variety of items and great flavor. After the wonderful meal, it was also nice to relax in the Onsen bath in my Room. The staff’s bright smiles were another highlight. I’d love to come back to enjoy seasonal dishes at a different time of year, and also explore the Onsen town and try visiting private baths at other facilities.

Thank you for the wonderful service—it made our stay truly exceptional. First, I accidentally made a Reservation with the wrong gender, but you quickly brought us yukata in different sizes, which was very helpful. With fewer guests staying, the attentive, personalized service really stood out. We also enjoyed the complimentary pudding—it was delicious. The Onsen was available at night as well, so we could relax and take our time. The bed felt a bit firm and slightly uncomfortable to sleep on, but other than that we had no complaints at all. Also, it was pouring rain at checkout, and you kindly handed us towels—this helped us so much. We truly appreciated your thoughtful attention to detail. We would love to stay here again when we visit Kusatsu.

Above all, the cuisine was outstanding. I also enjoyed the private open-air bath in my room many times. I’d love to visit again!

We visited to celebrate my father’s 80th birthday. It was a long drive from Yokohama to Nagano, but this was a wonderful Accommodation that truly made us glad we came. The in-room open-air bath was a little hot and needed some adjustment, but it was clean, spacious, and free of insects. The shampoo and conditioner also left our hair smooth and silky. (Some Ryokan at this level still leave your hair feeling rough.) All the staff who welcomed us were smiling, and during dinner the head chef served the main dish right at our table. Everything was delicious—made with local ingredients and carefully prepared with great attention to detail. On our way out, they even opened the souvenir shop in the main building earlier for us, so I was happy to be able to buy the souvenirs I wanted. My parents were very pleased as well, so we would love to visit again while they are still healthy.

From the moment we arrived at the entrance, we felt warmly welcomed. Every staff member was very pleasant, yet never intrusive, and we had a truly wonderful time. A wild squirrel even appeared on our Room terrace, and the birdsong was so soothing. We were also able to enjoy our meals at a relaxed pace. At checkout, we received kind words that made us feel glad we came—an Accommodation we would be happy to return to. We also enjoyed both Mt. Omuro and Mt. Komuro. Thank you very much.

The carefully prepared, healthy cuisine, the clean and stylish Room, the luxurious amenities, and the bath where you can soak while listening to the gentle murmur of the river—everything was deeply satisfying and made for a truly wonderful stay. What left the strongest impression was the hospitality of all the staff. There were several international staff members as well, and seeing them serve guests earnestly in Japanese and make an effort to embrace Japanese culture was heartwarming and put me at ease. This is an Accommodation I would love to visit again. Thank you very much for such a wonderful time.
