History
Tenoko Station opened on 10 August 1931 when the Yonesaka East Line was extended from Imaizumi, serving the town of Iide in southwestern Yamagata. With the extension to Uzen-Numazawa on 10 November 1933 it became an intermediate stop. Freight handling ended on 2 October 1972, full destaffing followed on 1 December 1975, and the station passed to JR East at the privatisation of Japanese National Railways on 1 April 1987. A new station building was completed on 21 December 2020. Services along this section of the Yonesaka Line have been suspended since the August 2022 flood damage to the line.
