• Nagasaki Main Line: Hizen-Oura ⇄ Nagasato

Konagai Station opened as a regular station on 1 December 1934, with the opening of the Ministry of Railways' Nagasaki Main Line between Tara and Yue stations (completing the Nagasaki Main Line's through route via Nagayo Station). Freight handling ended on 15 February 1962, and baggage handling ended on 1 April 1973, on which date the station also became unstaffed. It was transferred to JR Kyushu at the division and privatization of Japanese National Railways on 1 April 1987. The station building was rebuilt in March 1989. On 23 September 2022 it became a stop for the sightseeing limited express "Futatsuboshi 4047" when that service began, and at the same time the section from Hizen-Hama Station to Nagasaki Station, including this station, was de-electrified. In October of that year, the local volunteer group Konagai Machiokoshi-tai installed eight flower beds, and flower seedlings were planted in November. In February 2023, flower-bed art created by the group together with fourth-graders from Isahaya City's Konagai Elementary School was donated and installed.

Konagai Station is a ground-level station with one island platform serving two tracks, plus a siding on the station-building side that does not face a platform. Rather than a single-track-through arrangement, it uses left-side running, and an uncovered footbridge connects the platform to the station building. The station building carries the nickname "Heartful Konagai." Although unstaffed, it has a ticket vending machine that does not issue magnetic tickets. Trains bound for Isahaya starting or terminating at the station are scheduled in the morning and evening, but since the station cannot turn trains back itself, they run empty to Doizaki Signal Station to reverse. The station marks the northern limit of YC1-series operation on the Nagasaki Main Line: no YC1-series trains run north of here toward Kōhoku, where all trains are operated with refurbished KiHa 47 cars.
