The, commonly called, is a Japanese, narrow gauge industrial railway line in Tateyama, Toyama. It is operated by the Tateyama Mountain Area Sabō Office, which belongs to the Hokuriku Regional Development Bureau of the Ministry of Land, Infrastructure and Transport.
The line transports materials and workers for the construction/conservation of erosion control facilities of Jōganji River, such as dams. Unlike ordinary railways in Japan, the line is not regulated by the Railway Business Law nor the Tram Law, but by the Industrial Safety and Health Law. It means the line is not a public transportation, but solely a construction facility. However, the line is well known among railfans. This is one of few Japanese railways, or possibly the only surviving one, to use narrow gauge track. Also, it is one of the lines with the largest number of railway zig zags in the world. Because of its historical significance, the line is registered as a Monument of Japan.[1]
