• Nagasaki Main Line: Ichinuno ⇄ Utsutsugawa

Hizen-Koga Station opened on 2 October 1972 as a station of Japanese National Railways on a new inland section of the Nagasaki Main Line. It was unstaffed at the start (an entrusted attendant was later assigned) and was named with the "Hizen" prefix to distinguish it from Koga Station. With the breakup and privatisation of JNR on 1 April 1987, the station passed to JR Kyushu. The SUGOCA IC card became usable on 1 December 2012. The station was made unstaffed again on 14 March 2015. From 23 September 2022, the section of the Nagasaki Main Line from Hizen-Hama to Nagasaki, including Hizen-Koga, was de-electrified.

Hizen-Koga is a ground-level station with one side platform and a single track, and within the single-track section of the Nagasaki Main Line (excluding the old route) it is the only station that has been without passing facilities since it opened — from 2025 Higashi-Isahaya will be without them as well. Because the gap between the train and the platform is wide, fall-detection mats two cars long have been fitted along the platform edge.
