  • I was able to relax and enjoy the bath several times. Both dinner and breakfast were delicious and healthy.

  • We stayed in a detached guesthouse this time, and the Room was spacious, open, and very comfortable. The view of the five peaks of Mt. Aso from the Room was outstanding. The bath was large, with smooth spring water quality, and we were very satisfied. The meals, created using fresh ingredients, were all delicious. The bed and pillows were excellent as well, and we slept soundly. It’s a wonderful Accommodation with nothing to complain about.\nIf I had to mention anything, the Room didn’t warm up easily even when we turned the air conditioner temperature up quite high—perhaps due to its direction—and it would have been nice to have some furniture for storing clothes.
