  • The Onsen will amaze you!

    I think it’s outstanding for relieving lower back pain and fatigue. I was traveling by public transportation and usually had to take breaks because of my back pain, but the day after soaking in the Onsen here, I was able to walk all day without any pain. It was very gentle, not strongly scented, and truly a wonderful bath. As for the Facility, it felt a little old. The meals were generous in portion and very delicious. Although the Facility felt a bit dated, I was still able to relax comfortably. In any case, the Onsen was great! I’d like to visit again in winter.

    We had a very comfortable stay and were very satisfied.The Room was spacious and clean. There is both an indoor bath and an open-air bath, so you can relax at your leisure.It’s close to Owakudani, making it a convenient location for sightseeing. However, it may be inconvenient without a car (it seems they can drive you to the station if you ask at the front desk).
