  • I was impressed by the attentive service and the wonderful Accommodation!

    It was a wonderful Accommodation, just as rumored. The Onsen on the first floor was especially impressive. The staff were very courteous, and since we arrived 30 minutes before our scheduled meal, they kindly adjusted the dining time for us. When making the Reservation, I had ordered a birthday cake, and they also prepared a birthday melody on a music box, a small flower basket, and even celebratory bite-sized sekihan and sweets—it was truly touching.

  • Highly satisfied

    A friend and I decided to visit the Simose Art Museum, and chose this place—ranked No. 2 in the Chugoku region—as our Accommodation.It exceeded our expectations.A spacious, beautiful, spotless setting surrounded by nature, with thoughtful hospitality.The luxurious sense of space and choice of materials throughout the building reminded me again how wonderful it is—something you don’t often find in newer hotels.The staff were excellent as well,and above all, the bath was so spacious!!We were truly satisfied with everything.Next time, I’d love to come back soon with my parents.
