Mount Nikkō-Shirane Live Cam

Geological Formation

Mount Nikkō-Shirane, rising to an elevation of 2,578 meters, stands as the highest peak in the Nikkō National Park region of central Honshū. This stratovolcano is a composite of volcanic rock layers, formed through repeated eruptions during the Late Pleistocene epoch. The mountain’s complex structure features alternating deposits of andesite and dacite lava flows, interspersed with pyroclastic ash and pumice. The geological profile of Mount Shirane includes prominent lava domes—most notably the Me-Azuma and Oku-Shirane domes—whose rugged cliffs and steep crags offer dramatic terrain for advanced Mount Nikkō-Shirane hiking expeditions.
