Mt. Sukai

Mount Sukai is one of the 100 Famous Japanese Mountains. The 2,144-metre-high peak lies in the Ashio Mountains of Japan, on the border of Nikkō in Tochigi Prefecture and Numata in Gunma Prefecture. Mount Sukai is an old stratovolcano, but with the whole mountain covered in forest today it does not appear like a typical volcano.
