    [Recommended for mountain climbing] Enjoy a one-night stay at an inn boasting hot springs surrounded by the magnificent 100 famous mountains of the Southern Alps, where you can enjoy a variety of food and the mountains. We have prepared a plan that includes only dinner and does not include breakfast for guests who leave early in the morning for mountain climbing. Ashiyasu Onsen is a pure sulfate hot spring that is 100% free-flowing from the source, with no added water, and the soft, viscous water is highly satisfying for hot spring lovers, as it is expected to have effects on [beautiful skin] and [fatigue recovery]. Summer is mountain climbing! Recommended for staying before and after mountain climbing such as Kitadake Amanno-dake, Houou-san, Senjo-dake, and Kaikoma-ga-take. ■Food: At the restaurant <Dinner> We serve Japanese kaiseki cuisine using seasonal domestic ingredients, mainly from the local area. The sweet vegetables blessed by the clear streams of the Southern Alps and the odorless river fish are known for their deliciousness. For meat dishes, we offer healthy boar and pork, which is high in fat but low in calories and high in protein. *Menu contents may change depending on the season and availability of ingredients. ・Breakfast not included ■Hot spring 100% natural spring water, no heating or water circulation Enjoy the luxury of pure, healing water.
