HIDA RANGE

Japanese Hida-sammyaku, mountain group in the Chubu chiho (region) of central Honshu, Japan. The range stretches from north to south along the borders of Toyama, Niigata, Nagano, and Gifu ken (prefectures). With the Kiso and Akaishi ranges, it constitutes the Central Mountain Knot of Japan. The Hida Range was first referred to as the Japanese Alps in the late 19th century; the term now usually includes all three ranges, the Hida Range being known as the Northern Alps. The mountains chiefly consist of granite pierced through by crystalline rocks containing feldspar. Recent volcanoes, including Mount Norikura (9,928 feet ) and Mount Ontake (10,049 feet ), rest upon the granitic foundation. The Hida Range as a whole is characterized by rugged landforms dissected by deep river gorges. The highest peaks are found near the centre of the range, where Mount Yariga rises to 10,433 feet (3,180 m) and Mount Hotaka to 10,466 feet (3,190 m). Cirques (deep, steep-walled basins) and moraines (glacial deposits of earth and stones) occur in the higher levels of several major peaks. The eastern margin of the range is marked by a bold fault scarp that descends abruptly to the lowlands of the Fossa Magna, the great fissure that traverses central Honshu from the Pacific to the Sea of Japan. The northern end of the mountains also terminates in a precipitous cliff at the Sea of Japan, but the descent to the west is more gradual, merging into the Hida Highlands. The Hida Range is almost totally included in Chubu Sangaku National Park. It is well known as a centre of mountaineering and skiing. Several of the mountains' rivers, such as the Otaki and the Kurobe, have been harnessed for the production of hydroelectric power.
