• Hachiko Line: Gunma-Fujioka ⇄ Kodama

Tanshō Station opened on 1 July 1931 with the inauguration of the Kodama to Kuragano section of the Japanese National Railways Hachikō Line, located in what is now the town of Kamikawa, Saitama Prefecture. From 1947 the Nippon Nickel Railway (later Jōbu Railway) connected here for freight transfer until that line closed in 1986. JNR freight operations were abolished in stages between 1974 and 1986. The station passed to JR East at the 1987 privatisation and was made completely unstaffed in March 2012. The track layout was reduced from two opposed platforms to a single side platform in July 2015, and a new station building, designed around the winter-blooming cherry of Jōmine Park, opened in September 2019.

The 2019 station building was designed around the winter-blooming cherry blossoms of nearby Jōmine Park.
