A secluded Accommodation in Yonezawa’s inner retreat, Onogawa Onsen. Enjoy the renowned hot spring beloved by Masamune Date.

A tranquil Accommodation in Onogawa Onsen, inspired by Ono no Komachi, offering Yonezawa beef and skin-beautifying hot springs. Enjoy silica-rich waters with 100% free-flowing natural spring water, available 24 hours a day. Our popular “Beef Lover’s Set” lets you choose your main Yonezawa beef dish and savor “Japan’s Three Great Wagyu: Yonezawa Beef” along with chef-selected seasonal ingredients. Meals are guaranteed in a “private room or semi-private room” for peace of mind. In February 2022, our new River View Deluxe Japanese-Western Room reopened after renovation! The latest massage chairs in the guest rooms are also very popular (except in some Rooms). An atmospheric detached inn where every Room overlooks the pond.

  • I was deeply impressed by the heartfelt hospitality of everyone at Kajikaso. During my stay, I lost track of time and enjoyed a truly fulfilling experience. The kaiseki dinner was exceptional—each dish was carefully prepared, and I savored it with all five senses. I’d love to have it again. The Onsen was also wonderful; the water felt silky and moisturizing like a beauty serum, leaving my skin smooth. Since the bathing areas rotate by time, the scenery changes completely, which was great fun—I soaked in the Onsen four times during my stay and felt completely refreshed. Conversations with everyone at the Ryokan were delightful, and my mother was very satisfied as well. (Thank you)

  • We stayed as a family of three on the “Room Assigned on Arrival” Plan.Our Room was upgraded, which was a pleasant surprise. There was also a high-end massage chair, and we were able to relax and unwind along with the Onsen.All of the staff were polite and friendly, and their comfortable sense of distance left a great impression.The Yonezawa beef shabu-shabu dinner was delicious, and our whole family was very satisfied.Next time, we’d love to try the sukiyaki as well.In addition to its smooth feel on the skin, the Onsen had visible mineral deposits and a gentle sulfur scent, making it an experience we could enjoy with all five senses.Breakfast was healthy yet offered plenty of variety and generous portions—we left feeling completely full.Everything—from the meals and Onsen to the Room and service—was highly satisfying, and we felt it offered excellent value for money.We would definitely like to return again as a family.
