The Japanese Alps are a mountain range on the Japanese island of Honshu, where they form the eastern boundary of Hida and Etchin provinces in the center of the island. The highest peaks of Japan after Fuji-san are in this range, the highest of them being Hotaka-dake at 3,190 m (10,466 ft) and Mount Shirane at 3,192 m (10,472 ft).
Mount Ontake in the range is both a destination for pilgrimages and an active volcano, with eruptions in 1979 and 1980.
