Best Achi Hotels

"There are two large public baths, which are exquisitely decorated and have a foot bath overlooking the garden. The hotel parking lot is right next to the market, which is very convenient. Surprisingly, there are paper cranes at check out, which is convenient for stargazing/sea of ​​clouds. The dining room is super large."

"I really love hot spring inns like these in small places. As soon as I told the staff where I wanted to go, they arranged a car to take me there. The little boy's smile is so adorable. There's a Kannon Bodhisattva in the open-air bath. Sitting in the bath at night, I admired the full moon. Although the sky was filled with stars, it was too bright. I could only vaguely see some. At night, I strolled along the banks of the Achi River, listening to the rushing water and gazing at the dim yellow lights of the inns. At the foot of the mountain, I could see the Big Dipper with the moon behind me. It's a little inconvenient to get to from Tokyo, but the crowds are less and the experience is better. I'll wait for a chance to go stargazing in winter."

"－ The staff took the initiative to help us put our luggage in the room, and the room was clean and tidy. Since the comet cluster was reported, the hotel was notified early. The dinner was arranged at five o'clock. The food was diversified and very satisfied. The breakfast was still very rich. It takes about 10 minutes to drive to see the starry sky. The hot spring is comfortable, － indoors and outdoors. There are two other family hot springs, which can be used by the people, and there is no extra charge. There are two ping-pong platforms for playing. The staff is very considerate and proactive, and will stay next time."

"We spent two nights here and everything was flawless! The service and amenities were top-notch, and every meal—from dinner to breakfast—was carefully curated and delicious. Truly one of the best luxury onsen hotels in all of Japan"

"I booked two adults and two children (11 years old and 4 years old), but cooking and amenities were prepared by four adults. As for cooking, there were four adults on the app, so I made a reservation because I thought that it was good for children to cook for adults. (in the first place, you can't choose a child menu on the app, or you can't choose it. But the amenities were good for children) However, at check-in, the person at the front desk said, ”I have received a reservation for 4 adults and I can't change it from now on. If you can't believe it, please look at this order statement.” I was told that I didn't ask for a change, but I was disappointed. If the child's food does not advance during the meal afterwards, it is said that ”I don't eat at all”, and it is said that it is accused of the order mistake here. I thought the dish was a fireplace dish, but it was different. The best thing is to check out, and I'm going to make a claim statement. ”I've corrected it to two adults and two children,” he said, and it's easy to say that it's not a child fee, but it's a disgusting taste. As expected, even if I insisted that I had two adults and two children on the app and made a reservation for the child until the age ”Such orders have not come from travel agencies,” he said, without any sign of standing from the customer's perspective. I think it is natural to confirm how my inn is introduced on the app and how much it is as a management business on the inn side, but it was very unpleasant anyway. After that, I wasn't sure if I apologized, but I called the travel agency to confirm it, but I didn't know what I confirmed, so I just wanted to take responsibility for the travel agency. I told him when I checked out that I should check the app, but he didn't see it, so he didn't feel like he was close to the customer. It seems that he thinks everything is right."

"It was a pity that the flower peaches were over, but I am very satisfied with the very nice inn. It was a pity that there was no herb hot water but there was no Junbi and there was no morning coffee. It was the best thing to be able to birdwatching with a lot of birds coming to the open-air bath in the morning ✨ Also, I would like to stay when the peaches are in bloom."

"📍 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. ♨️🍁🌿✨"

"It was great to spend time, everything that was in the river was very enjoyable. But it was very, very difficult to get to. We from Nagoya wanted to take a bus, but the tickets for all the buses all ended in the morning. That's why I had to take a taxi. From Nagoya to the river the cost of a taxi 50,000 yen. It's very expensive. It's a pity there was no information anywhere that you need to buy bus tickets in advance."

"I would like to take a moment to express my sincere appreciation for the excellent service provided by one of your hotel staff members, Ito-san. During my stay in Hirugami No-Mori, Ito-San went above and beyond to ensure that our experience at your onsen/hotel was a memorable one. Despite the language barrier, Ito-san's attentive nature and willingness to go above and beyond to assist me in navigating the area made a significant difference in my stay. Her use of Google Translate to communicate with us was impressive and demonstrated her dedication to providing top-notch service. I was thoroughly impressed with her professionalism, positive attitude, and exceptional customer service skills, which were evident in every interaction I had with her. Her talent is remarkable, and I hope that your hotel will continue to support and develop her professionally. Please convey my heartfelt appreciation to Ito-san, and please recognize her outstanding work. She is a true asset to your onsen/hotel, and I look forward to visiting again in the future. Thank you for providing me with a memorable experience, and I wish you and your team continued success."

"Breakfast and dinner are very good! The food materials are fresh."
