Kojima Station opened on 20 March 1988 in present-day Kurashiki, Okayama Prefecture, when the new Honshi-Bisan Line began operating between Chayamachi and Kojima ahead of the 10 April 1988 opening of the Great Seto Bridge. As the last station in Honshu before the bridge crosses to Shikoku, it serves as the boundary station between JR West and JR Shikoku, with the company demarcation near the Utazu-end signal. JR West owns and operates the facilities while JR Shikoku maintains a crew room on platforms 3-4. Two elevated island platforms serve four numbered tracks. ICOCA was accepted from 1 September 2007. In 2015 the station gained the nickname "Jeans Station" celebrating Kojima as the birthplace of Japanese-made jeans.

JR Shikoku assigns no station number to Kojima, the only station on its network without one; JR West, which numbers it JR-M12, owns the station facilities and handles all station operations.
