Kōyōdai Station opened on 1 November 1986 as an unstaffed station on the Yosan Line. Operation passed to JR Shikoku on 1 April 1987 with the privatisation of Japanese National Railways. The station has a single side platform serving one track, with no station building — only a passenger shelter and a small kiosk containing an automatic ticket vending machine. Only Yosan Line local trains stop here, operating in the sector between Iyo-Saijō and Matsuyama; connections at neighbouring stations are needed to travel further along the line.
