  • It was a very relaxing Accommodation. Although the building has a sense of history, it was thoroughly cleaned and well maintained, so we enjoyed a very comfortable stay. The staff kindly accommodated many of our requests, and we truly appreciate it. Of course, the service was excellent! The meals were also delicious, including Yonezawa beef filet steak and shabu-shabu. The semi-open-air bath in the Room was supplied with natural hot spring water, and the quality of the water was wonderful. It is an Accommodation that made us want to come back for a Multiple Night Stay.

  • It was a girls' trip with my elderly mother and sister. Although we were initially concerned about bears, the peaceful and spacious environment made us completely forget about it, allowing us to relax and unwind. The place was impeccably clean, and we truly appreciated the thoughtful consideration for our food preferences (meat or fish). My mother has already expressed her desire to visit again. Thank you for taking care of us!
