The station consists of an island platform and a side platform serving three tracks. The present station building, completed in 1975 is a hashigami (橋上) structure where passenger facilities are located on a bridge which spans the tracks. Besides providing access to all the platforms, the enclosed bridge structure houses the ticket gates, a waiting room, shops, a JR Midori no Madoguchi ticket window and a JR Travel Centre (Warp Plaza).[2][5][6] A passing loop runs on the side of platform/track 1. In addition, a large freight yard is located just to the east of the station which is leased by a paper manufacturer.[3]
Iyo-Mishima Station opened on 16 September 1917 as the terminus of the then Sanuki Line which had been extended westwards from Kawanoe. It became a through-station on 1 September 1919 when the line was further extended to Iyo-Doi. At that time the station was operated by Japanese Government Railways, later becoming Japanese National Railways (JNR). With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku and JR Freight.[7][8]
