An inviting open-air Onsen is the highlight. A relaxing Accommodation nestled in the great nature of Kumano.
An Accommodation proud of its beautiful scenery, surrounded by the mountains of Kumano and the Oto River. Please relax and enjoy the open-air Kawayu Onsen, as well as Kawayu Midori and the large public bath. For dining, enjoy a buffet featuring a menu made with carefully selected local ingredients.
It was conveniently located with easy access to Kumano Hongu Taisha. The Accommodation was new and comfortable, and the meals featured dishes inspired by Wakayama—there’s no other way to describe it than pure happiness.Being soothed by nature and the Onsen made this an amazing trip. I’ll definitely come back!If I had to mention one thing, could you consider setting time limits for the lounge? I could hear people staying there for long periods chatting, and since I couldn’t use it, that was a little disappointing.
@サバ缶大好き 8/13/2026The outdoor river hot spring was incredibly relaxing.Large carp streamers were gently swaying in the wind,and while watching the sky, greenery, and the flowing river,it was wonderful to soak slowly both in the evening and in the morning.Even though it’s mixed bathing, you bathe wearing a yukata-style bathing garment, and there are separate areas for men and women as well, which was reassuring.When we got too warm, we’d go dip our feet in the river for a bit. We felt so happy being able to relax in nature.The meals were delicious, and there were alcoholic drinks and soft drinks too, so we enjoyed them freely at our own pace.Everyone at the Accommodation was very kind,and it was also really nice that it was quiet since we came right after Golden Week ended.My friend and I were saying we definitely want to come again next time. Thank you for taking such good care of us.The photo is of the river view from our Room.
