Chōkai Sanroku Line

The Chōkai Sanroku Line (鳥海山ろく線) is a Japanese railway line in Akita Prefecture in northern Japan, with all station located within the city of Yurihonjō. This is the only railway line operated by the Yuri Kōgen Railway (由利高原鉄道).

History
On August 1, 1922, the privately owned Yokote Railway Company (横手鉄道) completed its West Line, connecting Ugo-Honjō with Maegō over 11.6 rail kilometers, and renamed itself the Yokojō Railway Company (横荘鉄道). The line was nationalized on September 1, 1937 becoming the Japanese Government Railway (JGR) Yashima Line (矢島) and the line was extended by an additional 4.1 kilometers to Nishitakisawa by December 15 of the same year. The line was further extended an additional 7.3 kilometers to its present terminus at Yashima by October 21, 1938.

The JGR became the Japanese National Railways (JNR) after World War II. All scheduled freight services were discontinued from March 10, 1981. In 1985, the operations of the former Yashima Line were taken over by the third sector company Yuri Kōgen Railway.

Proposed connecting line

 * Maego Station - The Yokote Railway Co. opened a 38 km line from Yokote on the Ou Main Line to Oikata between 1918 and 1930. Construction commenced on an extension to this station but it was not completed. The 12 km section from Oikata - Niiyama was closed following typhoon damage in 1947, the 7 km section from Niiyama - Tateai closed in 1965 when a bridge was destroyed by floodwaters, and the balance of the line closed in 1971.
