The Chōkai Sanroku Line (鳥海山ろく線, Chōkai Sanroku-sen^?, "Chōkai Submontane Line") 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 of Yuri Kōgen Railway (由利高原鉄道, Yuri Kōgen Tetsudō^?).

On August 1, 1922, the privately owned Yokote Railway Company (横手鉄道, Yokote Tetsudō^?) 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, Yokojō Tetsudō^?). The line was nationalized on September 1, 1937 becoming the Japanese Government Railway (JGR) Yashima Line (矢島, Yashima sen^?) 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.
