Akadake Kōsen (赤岳鉱泉)

Akadake Kōsen is one of the most important “base-camp” huts in Southern Yatsugatake. It’s famous for being open year-round, for its winter artificial icefall (Ice Candy) scene, and for offering an unusually comfortable stay for a mountain hut (good meals, modern facilities, and a bath in the green season). It also runs a large, organized tent site, making it a natural hub for staged climbs toward Mt. Akadake and Mt. Iō (Iodake).
