(For mixed bathing, wearing a bathing garment is required.) Surrounded by nature far from the bustle of town, relax at your leisure while taking in the magnificent views of Mt. Ontake.

  • With exceptionally courteous service, you can enjoy a comfortable stay.

    From the warm welcome to the courteous service and attitude of all staff, this Accommodation was excellent. The building was also well cleaned and very comfortable to stay in.Unfortunately, we were not blessed with good weather and could not see a sky full of stars, so I would like to visit again someday.I rated the bath 4 stars because the outdoor mixed-gender bath was too lukewarm, so I deducted one point.

  • The meals were excellent.

    Dinner was absolutely delicious and wonderful. I was especially impressed by the kombu-cured Shinshu salmon—it was outstanding. Because of the rain from Typhoon Maekala (No. 7), I couldn’t fully enjoy the open-air bath in the Onsen. If I have another chance, I’d love to soak while gazing at a sky full of stars.

Open-air bath at night
Large Public Bath
A large bathhouse (indoor bath / open-air bath) with free-flowing natural hot spring water, “Golden Hot Spring,” and a rare mixed-gender open-air bath (bathing wear required for mixed bathing).

During the day, you can enjoy views of Mt. Ontake from the mixed-gender open-air bath, and at night, a sky full of stars. The spring water is colorless and transparent at the source, but when exposed to air, ferrous iron ions oxidize and turn a golden color. The spring quality is a sodium–magnesium–calcium bicarbonate/chloride spring. It is said to be beneficial for cuts, sensitivity to cold, depressive moods, and dry skin conditions. In the large public bath, we offer a “shampoo buffet.” Please try our selection, including shampoos from Kiso Town brands.
