  • We had a comfortable stay.

    Although we were concerned about traveling during the Obon season and with unstable weather, we arrived safely with no issues on the roads. The welcome was attentive as always, and the familiar atmosphere made us feel at ease. The Room was clean, and the open-air bath was at a comfortable temperature, allowing us to relax. The meals featured many locally sourced ingredients, were perfectly portioned, and truly delicious. We had another wonderful stay and will visit again.

  • I was very satisfied!

    I stay here around the same time every year. This year again, I was able to truly relax and feel refreshed. The staff were attentive, and everyone was wonderful. There are more foreign attendants now, but their Japanese is excellent, and I imagine they are well received by international guests as well.I use a wheelchair, and the considerate support provided was just right, making my stay even more comfortable. Having an Onsen in the Room that I can enjoy anytime is also fantastic. I would love to come back again for a relaxing stay. Thank you very much.
