Experience a special time of relaxation with the flowing Onsen waters at the "Villa" of Kurokawa Onsen.

Twenty-five years ago, Yamamizuki was born in Oku-Kurokawa Onsen. Miyama Sanso was created to carry on that spirit—yet it offers a fresh experience all its own. With an even deeper connection to nature, Miyama Sanso features a main building and ten detached villas with 18 Rooms.

  • The hot spring water was gentle on the skin, with a temperature that was just right—neither too hot nor too lukewarm—and we thoroughly enjoyed everything from the large public bath to the private bath in the annex. The meals were not served in our Room, but it was pleasant to take a walk after bathing. Every dish was excellent; the ingredients were high quality, expertly prepared, and truly delicious. We were also deeply comforted by the kind hospitality of everyone at the Accommodation. We would definitely like to visit again. The only reason I gave 4 points for Facilities is that the refrigerator was located farthest from the living area, in the changing room/vanity area, which was a bit inconvenient to use. Other than that, we were completely satisfied.

  • Until we arrived, my husband and I kept wondering, “Are we on the right road?” But when we reached Miyama Sanso, we were amazed by the absolutely wonderful location! The Room was a private standalone villa, and the bath was fed directly from the source with free-flowing Onsen water. Meals are served in the dining area, and once again we were impressed by the staff’s service and how delicious everything was. We were able to enjoy a relaxing adults-only getaway. The Onsen water was simply perfect, and it left our skin feeling silky smooth. We were also delighted that two types of loungewear were provided: samue and pajamas. This is an Accommodation we would love to visit again—worth flying back for.
