  • Rock Garden Open-Air Bath

    As advertised, the rock garden open-air bath was outstanding. We were also very satisfied that we could use the Prince Onsen for free.

  • The mixed-gender open-air bath is exceptional.

    The mixed-gender open-air bath offers dedicated towels (separate for men and women) and allows you to enjoy a variety of baths while admiring the vast natural surroundings. Bathing suits are also available for purchase, with cute designs for women. It's perfect for couples to relax in the bath without worrying about others. Guests can use the baths of two hotels, with shuttle service provided between them. The dinner buffet features a wide selection of dishes, with smooth replenishment, allowing guests to enjoy plenty of food. The warmth of the staff made it a hotel I would love to visit again.
