History
Mount Hirogōchi is a high peak in the Akaishi range, sitting on the ridge continuing from Mount Notori, and it serves as the boundary from which the mountain area to the south is named the Shirane South Ridge. Known as one of the Hundred Mountains of Kai, it stands quietly amid the deep nature of the Southern Alps. For details of its climbing history and the origin of its name, please check official information.
Access
It lies on the border of Hayakawa, Yamanashi, and Aoi-ku, Shizuoka City, around 35.61°N, 138.24°E. The common approach follows the ridge from the Mount Notori side as an extension of a Shirane Three Peaks traverse, requiring full mountaineering gear and planning. Always confirm trail conditions and access information via official sources.
Best season
From high summer, when the snow has melted and alpine flowers bloom, into early autumn, when the ridge air is clear, is the climbing season. At 2,895 meters the weather changes fast, so warm clothing and sound weather judgment are essential.
