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

Nestled in Shima Onsen, "Ayameya Ryokan" is a tranquil Onsen retreat surrounded by nature, where you can enjoy the seasonal landscapes. The area is dotted with waterfalls and lakes, perfect for leisurely strolls. You can also enjoy water activities in the clear Shima River. The Ryokan offers five 10-tatami mat Japanese-style rooms, each providing serene and calming spaces with windows that showcase the seasonal mountain scenery. Shima Onsen is designated as a National Health Onsen, featuring gentle waters that are safe for small children and expectant mothers. Additionally, we serve dishes prepared with an abundance of fresh, seasonal ingredients, highlighting the blessings of the mountains and rivers.

  • 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.

  • We stayed as a couple. We chose a Plan with breakfast and dinner, and there were so many dishes—everything was delicious. Among all the Ryokan we’ve stayed at, this one offers by far the best value for the meals. The private bath was also included in the Plan and we really enjoyed it, and all the staff were courteous and attentive—we felt very well taken care of. We will definitely stay again.
