A traditional Japanese-style Accommodation built in the sukiya-zukuri style, where you can fully enjoy free-flowing natural hot spring baths.
A traditional Sukiya-style inn surrounded by nature, offering the beauty of all four seasons. In spring, enjoy cherry blossoms; in summer, hibiscus and fireflies; in autumn, colorful foliage and ginkgo trees; and in winter, camellias and snowy landscapes. The garden at Shaga no Sato Yumeya blooms with seasonal flowers year-round, allowing you to fully experience nature and the changing seasons.
You’ll head toward the mountains on a narrow road that might make you wonder if there’s really a Ryokan up ahead.When we finally arrived, it felt like a hidden Accommodation—so exciting!The building was spotless and well maintained, and the staff were friendly, making it truly relaxing. The Onsen had a sulfur scent, and the meals—centered around fish—were delicious down to the pickles. I couldn’t stop going back for more rice!We made our next Reservation as soon as we arrived—it was that wonderful!
おまめの休日 6/8/2026We stayed in the annex and had a very comfortable time. It was a hot day, so it was a shame we couldn’t relax on the bath terrace. We think it would be even more comfortable if the bath building and living quarters were connected by a covered walkway. We also felt the garden could use a bit of pruning. The conger eel soup at dinner was delicious, with a flavor that made us feel as if we were in Kyoto. Many of the staff were energetic and cheerful, which surprised us at first, but we felt it was a nice distinctive touch compared to other places. Thank you very much to everyone.
