History
Koga Station opened on 28 September 1890 as an intermediate stop when the privately run Kyushu Railway opened its Hakata - Akama section. Following nationalization on 1 July 1907, the station passed to JR Kyushu on 1 April 1987 after the breakup of JNR. The station was rebuilt with a bridge-type building on 22 December 1989. It was demoted from rapid-service stop to local-only in 1980 but progressively regained service: partial rapid stops from 22 March 1997 and full rapid-service status again from 3 March 2001. Automatic gates were installed in February 2000, SUGOCA on 1 March 2009, and the station returned to direct JR Kyushu operation on 1 October 2023.

Notes
When the station was rebuilt in 1910, salvaged materials from Kashii Station were reused for its replacement building — an early example of station-component recycling on the line.
