A Resort Hotel in the forest offering sports experiences the whole family can enjoy

Renovated and reopened in April 2018! Enjoy a 1,500-square-meter Onsen beach with natural hot springs, an athletic park in the forest, and many activities perfect for families and children.

  • I have used this facility multiple times, and this was my first visit since the children's play area was renovated. The play area has been greatly improved, and my child was very satisfied. We were able to enjoy a wonderful time, including the meals. However, there were two disappointing points: 1. There was a stain on the room's sofa that looked like a bedwetting mark, but no explanation about it was provided. 2. To access the room via elevator, you need to use a card key; however, only two keys are provided per room. The Room is spacious enough for up to five adults, but having only two card keys is quite inconvenient. I hope this can be improved in the future.

  • I visited with my daughter and two grandchildren. Although there was no notice at the time of Reservation, some construction work was being carried out, so we were disappointed that we couldn't use the Facility we were looking forward to. However, as compensation, there were free Facility usage and complimentary snacks provided. The meals were served buffet-style with a wide variety of dishes, including delicious local specialties made from regional ingredients. The view from the Room was spectacular, allowing us to fully enjoy the beauty of nature.
