Plum blossoms, cherry blossoms, and the scent of spring invite the warbling of the bush warbler. In summer, the chorus of cicadas. In autumn, the vibrant colors of the leaves. And in winter, the serene silence of snow piling up. We hope you can enjoy a moment of peace, freed from the routines of daily life, amidst the rich expressions of the four seasons. The hot spring source is located just behind our facility. With no heating, no added water, and no impurities, it is 100% pure natural Onsen. We hope it will help you fully recover from the fatigue of your journey. Additionally, dinner for all Plans will be served in your Room, allowing you to relax and savor your meal at your leisure.
