A pass in the Hidaka Mountains in central-southern Hokkaido. It is 644 meters above sea level. Its name comes from its location on the border between Ishikari Province and Tokachi Province. National Route 38 crosses the Hidaka Mountains, an artery of transportation connecting eastern and western Hokkaido. In 1907 (Meiji 40), the Karikachi Tunnel (953 meters long) was dug under the pass, and the JNR Kushiro Line (now part of the JR Furano Line and Nemuro Main Line) was opened. It was known for the vast view it offered when passing through to the Tokachi side. Later, in order to ease the steep gradient of 20 to 25 thousandths and the sharp curves, construction of the new Karikachi Tunnel (5,647 meters long) began about 4 kilometers south of the pass in 1962, and was completed in 1966. The maximum gradient is 12/1000. The view from the tunnel is gone, but you can see the Tokachi Plain from the observation deck at the pass.

北海道中南部にある日高山脈(ひだかさんみゃく)の峠。標高644メートル。地名は石狩国(いしかりのくに)と十勝国(とかちのくに)の境界に位置することによる。道東と道西を結ぶ輸送の動脈で国道38号が日高山脈を横断している。1907年(明治40)峠下に狩勝トンネル(延長953メートル)をうがち、国鉄釧路線(くしろせん)(現、JR富良野(ふらの)線および根室(ねむろ)本線の一部)が開通し、十勝側へ抜けたときの広大な展望で知られた。その後、1000分の20~1000分の25の急勾配(こうばい)と急カーブを緩和するため、1962年峠の南方約4キロメートルに新狩勝トンネル(延長5647メートル)建設に着手、1966年完成した。最高勾配は1000分の12。トンネルを出たときの景観は失われたが峠の展望台からは十勝平野を一望できる。 [古川史郎] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
