Route map

The Takayama Main Line (高山本線, Takayama Honsen) is a Japanese railway line between Gifu Station in Gifu and Toyama Station in Toyama, operated by Central Japan Railway Company (JR Central) and West Japan Railway Company (JR West). The line directly links the Chūkyō Metropolitan Area (metropolitan Nagoya) and Hokuriku region in a shorter distance, but with a longer travel time, than by using the combination of the Tōkaidō Shinkansen and Hokuriku Main Line. Now the line primarily functions as a way to access the scenic areas of Hida (ancient Hida Province), in the rugged mountains of northern Gifu Prefecture, such as Gero onsen (hot spring), Takayama, Shirakawa-gō, and the Kiso River. The first section of the line, between Gifu and Kagamigahara, opened in 1920 (1920). The whole line was completed in 1934.

History

The Gifu to Mino-Ota section opened in 1920, and the line was then extended in sections, opening to Gero in 1930 and Hida-Osaka in 1933. At the northern end the first section from Toyama opened in 1927, reached Inotani in 1930 and Takayama and Hida-Osaka in 1934, completing the line.

Between 2004 and September 8, 2007, the section between Tsunogawa Station and Inotani Station was closed due to flood damage from Typhoon Tokage.^[2]

Former connecting lines

• Hida-Osaka Station: The 762 mm (2 ft 6 in) gauge Kosaka Forest railway commenced operation in 1933, and by 1953 consisted of seven lines with a total length of 65 km. Line closures commenced in 1954, and the system closed in 1971.^{[citation needed]}
• Inotani Station: The 610 mm (2 ft) 24 km line to Kamioka-Cho (which was opened in 1910 by the local government from Sasazu station) was acquired by the Mitsui Mining Co. in 1927. In 1931, a 2 km line to alter the connection to Inotani Station opened (with the 16 km section providing the Sasazu connection closing at the same time) and an 8 km branch opened in 1937, connecting to the 762 mm (2 ft 6 in) gauge Sugoroku-Kanakida Forest railway (which consisted of a 16 km main line and three branches between 3 and 6 km in length, and operated from 1930 to 1963). Passenger services ceased in 1962, and the mine and railway closed in 1967.^{[citation needed]}
• Sasazu Station: As mentioned above, the 610 mm gauge 24 km line to Kamioka-Cho operated from 1910 until altered to connect at Inotani station in 1931. The Toyama Railway operated a 12 km line to Minami-Toyama between 1914 and 1933. In 1943, the Toyama Electric Railway reopened the line, electrified at 600 V DC, and operated it until 1975.^{[citation needed]} The 20 km Kamioka Line to Okuhida-Onsenguchi opened in 1966. Freight services ceased in 1981, and the line closed in 2006.^{[citation needed]}
