A journey of hot spring hopping and gourmet dining, featuring four natural hot springs and locally sourced ingredients

This Property offers the unique experience of enjoying Onsen with different colors and water qualities from four distinct sources. In particular, the "Stone Garden Open-Air Bath," where you can enjoy milky white water, yellow water, and clear water, provides a special space unique to highland Onsen, accompanied by a magical landscape. Additionally, the quietly flowing time here offers a luxurious tranquility that cannot be experienced in the city. The Room accommodates up to 4 guests and includes free Wi-Fi access. There is also a buffet restaurant featuring an abundance of seasonal local ingredients.

  • 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 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.
