The Hida Mountains (飛騨山脈 Hida Sanmyaku, Hida mounain range), or Northern Alps, extend through Nagano, Gifu, Toyama, and partially into Niigata prefectures. Its length is 105km or 65 miles.
Norikuradake (乗鞍岳), or Mt. Norikura, plays a chief role in the story of Hida, as we have seen in the previous posts. Norikuradake at the southern part of the Hida Mountains is the third tallest volcano in Japan. Norikuradake’s name means “riding saddle” because of its shape.
The above photo from a postcard is a view to the east from Takayama. It shows the Hida Mountains, with northern part on top and Norikuradake, the southern part, on the bottom. The peaks and a plateau are labelled as follows. Take (dake in compounds) means peak; mine also means peak; taira means plateau. The coordinates are approximately 36 N 137 E.
