Mt. Omanakosan

大真名子山

Nikkō-shi, Tochigi · Elevation 2,375 m

Mount Omanakosan (2,375 m) is a 470,000-year-old andesite-dacite lava dome on the main Nikko ridge in Nikko City, Tochigi, within Nikko National Park. In local lore the peak is the child of Mount Nantai (father) and Mount Nyoho (mother), with the neighbouring Mount Komanak as its sibling. A subsidiary shrine of Nikko Futarasan Shrine sits on the summit, and the popular climbs cross over from Shizu Pass to Mount Nantai or from the Kirifuri Highlands. The peak is included in the Tochigi 100 and Kanto 100 Mountains selections.
