Hot Spring Hotels in Achi

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

－ 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.

📍 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. ♨️🍁🌿✨

Far from train station. Difficult to get to by public transport but that is the beauty of it. We got a transfer with the hotel (additional charges). Had to get a friend to translate emails into japanese to send to the hotel. All the staff we encountered in Nov 2018 were polite and welcoming but do not speak english at all. The Google translation app is very useful to get around the language barrier. Small, quiet and beautiful place! Quite literately surrounded by mountains.
