An Onsen resort surrounded by the gentle murmur of Yoro Valley’s stream

  • This was the most wonderful stay I’ve ever had at any Accommodation, in Japan or abroad. Onsen: Not only is the water quality exceptional, but the temperature is perfect—so soothing you’ll want to soak again and again! Room: Impeccably clean, beautifully styled, and incredibly comfortable in every way. A space that lets you completely forget the noise of everyday life. Dining: Each dish felt like a work of art, with delicate seasoning throughout. We enjoyed local seasonal ingredients at their very best, and every bite was moving. Above all, the staff’s hospitality was outstanding. With a perfectly balanced sense of distance while anticipating even our smallest needs, their thoughtful service truly impressed us. Their warm smiles and kind words were deeply comforting. Without a doubt, this is my best Accommodation ever. I will definitely be back as a treat for myself. Thank you for such a wonderful time.

  • The location, Facility, and service are all excellent—this is a wonderful Accommodation. The open-air bath overlooking the valley was perfect for a refreshing change of pace. They kindly provided Shuttle Service by buggy to our Room without showing any displeasure, and my parents—who have been traveling abroad less due to mobility issues—were truly delighted. Thank you very much!
