  • The Room with an open-air bath was just as expected, but the dinner and Japanese breakfast were even more wonderful than I had hoped! I was impressed by the beautiful presentation and delicate flavors. The staff’s service was also very attentive, and their hospitality truly stood out. I would love to stay again if I have the chance!!
