Shin-Koshigaya Station opened on 23 July 1974 to give Tobu's Skytree Line an interchange with Minami-Koshigaya on the year-old Musashino Line; transfer passengers had previously walked roughly one kilometre from Gamo. Land negotiations delayed the opening by about fifteen months. Elevation work began in 1989; down platforms were raised on 8 October 1993 and up platforms on 2 November 1994. Quadruple-tracking south to Soka was completed in March 1997 and the station became a semi-express stop at the same revision. A five-storey building housing the Varie shopping complex opened on 26 March 1998. Station number TS-20 was assigned on 17 March 2012, and platform edge doors entered service on platforms 1 and 4 on 27 February 2021 and on platforms 2 and 3 on 7 March 2021.

Because the Musashino Line had been built elevated first, the later raising of the Tobu line required Shin-Koshigaya's platforms to span across the JR viaduct at roughly the height of a five-storey building.
