A soothing getaway with seasonal nature, Onsen, and homemade cuisine

Ayameya Ryokan, nestled in Shima Onsen, is a quiet hot-spring destination surrounded by nature where you can enjoy the scenery of all four seasons. Waterfalls and lakes are scattered throughout the area, making it perfect for leisurely walks. You can also enjoy playing in the clear waters of the Shima River. Our five 10-tatami Japanese-style rooms offer peaceful, relaxing spaces with seasonal mountain views from the windows. Shima Onsen is designated as a National Health Hot Spring and is known for its gentle waters, making it safe and comfortable even for small children and pregnant guests. We also serve dishes featuring fresh seasonal ingredients, generously using delicacies from both the mountains and the river.

  • As I’ve gotten older, I’ve been looking for an Accommodation that doesn’t serve meals buffet-style, and we chose Ayameya Ryokan based on its great Reviews.Throughout the property—not only the Room, but also the baths, changing area, and toilets—everything felt impeccably clean.The meals were full of thoughtful touches, such as a creatively arranged chawanmushi and tempura enjoyed with miso. It was quite a generous amount, but it was so delicious that we finished everything. The breakfast rice porridge was also a welcome treat.The Onsen had soft, gentle water, and I was able to soak slowly as if it were a private bath without running into other guests. (The open-air bath felt a little lukewarm for me.)I’d been staying mostly at large Hotels lately, so this time I truly experienced how wonderful a Ryokan can be thanks to the cheerful proprietress and the attentive hospitality of all the staff. It became an unforgettable Onsen trip—simply the best!To the proprietress: please take good care of yourself, and I hope you also get chances to relax and be pampered from time to time.

  • It was a wonderfully attentive Accommodation. The food was delicious—above all, the rice was outstanding. The grilled fish was cooked perfectly, and the sashimi was fresh and very tasty. I was also very happy with the late-night rice ball and message.Breakfast had a great variety and was exciting as well. Personally, I especially appreciated having rice porridge. It was raining when we left, but thank you for carrying our luggage to the car. You also lent us an umbrella, so we were able to get to the car without getting wet. I forgot something behind, but I can only be grateful for your kind and careful assistance. I would definitely like to stay again. Thank you for letting us relax and enjoy our time there.
