  • Very satisfied!

    First of all, the Onsen was excellent—the bath size, temperature, and water quality were all wonderful. The fresh sashimi and abalone were also outstanding. I stay at various Accommodations throughout the year, and this was an Accommodation I would definitely like to visit again. Thank you very much!

  • Great hot spring water! Even better service!!

    This accommodation is truly exceptional, starting with the amazing bath! During the cold wave in January, we enjoyed alternating between the private open-air bath in our room and the refreshing outdoor air, which was incredibly rejuvenating. The atmosphere of the room was also wonderful—calm tones, a sense of cleanliness, and a unique blend of extraordinary ambiance with a comforting homely feel. The cuisine was outstanding as well; it was evident that fresh ingredients like meat, fish, and vegetables were carefully prepared. The portions were generous, leaving us fully satisfied both at breakfast and dinner. The staff who served us were all delightful and provided excellent service beyond our expectations for even our meticulous requests as a couple. Thanks to them, we had an extraordinarily special holiday. We usually discuss "Where should we go next?" after trips but found ourselves saying "We want to come back here again" from the bottom of our hearts for this incredible accommodation. Thank you very much!
