  • A Hotel that satisfies both your eyes and appetite.

    I visited with my mother. First, we were soothed by the lush green scenery, and thoroughly satisfied with the unique buffet selection. We kept saying "so full!" while enjoying the all-you-can-eat crab. Soaking in the Onsen, I was able to give my mother a truly wonderful experience.

  • The best dining experience

    Dinner was a buffet with all-you-can-eat crab, and there were so many other dishes that it was impossible to try them all. Breakfast was a buffet that included traditional New Year's dishes, and again, the variety was abundant and very satisfying. I definitely want to visit again next year.
