Shiga Kogen Yakebitai is a high-altitude onsen at Shiga Kogen—Japan's largest ski resort plateau, developed on a UNESCO-registered nature reserve in the Jōshinetsu Kogen National Park at elevations between 1,500 and 2,300 meters—where the name 'Yakebitai' (burned brow) refers to a historic volcanic eruption that shaped the dramatic highland terrain now traversed by Japan's most extensive interconnected ski resort network. The siliceous thermal waters warm skiers, hikers, and nature observers who explore the Shiga Kogen plateau through its four distinct seasons: powder snow sports in winter, wildflower meadows in summer, and spectacular foliage in autumn within a volcanic landscape that remains seismically active. The proximity of the famous Jigokudani Snow Monkey Park—where Japanese macaques bathe in outdoor onsen pools just kilometers away—adds a dimension of natural wonder unique to this Nagano highland thermal region.
