- Yamanami Inn in Oku-Aso
Relax and rejuvenate from daily fatigue with 100% natural hot spring water, exquisite cuisine prepared with renowned water, and the calming sounds of nature.
At the Property Yamanami, nestled in the quiet area of Oku-Aso, you can enjoy 100% natural Onsen with a pH of 9.2 and local cuisine made with water from the Ikuyama spring, one of Japan's top 100 water sources. From the single-story Property surrounded by trees, you can feel the seasonal colors, and the Japanese-style interior soothes your daily fatigue. Additionally, there are gender-swapping large communal baths and private family baths, offering dishes centered on local mountain vegetables, meat, and fish. Spend a pleasant time in the garden, where the scenery changes with the seasons.
We stopped by during a drive trip to Mt. Aso. We traveled with our 1-year-old child, and we really appreciated the thoughtful consideration for meals. The food was delicious, and the open-air bath was excellent. We would love to visit again if we have the opportunity.
Yahoo!トラベルユー... 7/23/2026The Ryokan’s atmosphere and hospitality were excellent.The meals, the Onsen—everything was wonderful.Thank you for allowing us to check in early due to the rain.We were very satisfied, as we wanted a calm, relaxing stay rather than being in an Onsen town.

Introduction of the Accommodation

The murmur of the stream... The rustling of the trees... The chirping of small birds can be heard, allowing you to feel the colors of the seasons in a tranquil place.

The main building was created using a traditional Japanese house that is over 100 years old. It is a Property with a warm and nostalgic atmosphere, reminiscent of visiting your grandmother's home in the countryside. While there may be some inconveniences due to its location in the mountains, we hope our guests can relax amidst the seasonal nature, rejuvenate from their fatigue, and relieve the stress of daily life. Our pride at Yamanami lies in the abundant nature surrounding the Property, the seasonal dishes carefully prepared with wild vegetables and local ingredients, and the handmade baths crafted with dedication by the owner. We offer natural hot spring baths, including open-air baths, indoor baths, and family baths.
