Ōkusa Station

The station is served by the old line or the Nagayo branch of the Nagasaki Main Line and is located 7.2 km from the branch point at Kikitsu.^[3] Only local trains run on this branch.^[4]

The station consists of two side platforms serving two tracks with a siding branching off track 1. The station building is a v-shaped modern timber structure which is unstaffed and houses a waiting room with a SUGOCA farecard reader. Access to the opposite side platform is by means of a footbridge.^[3][2][5]

The private Kyushu Railway, had opened a track from Tosu to Saga by 5 May 1895, and thereafter expanding southwards in phases, as part of the construction of a line to Nagasaki. Separately, a track was laid from Urakami (then known as Nagasaki) north to Nagayo, which opened on 22 July 1897 as the terminus. On 27 November 1898, a link up was made between Nagayo and the track from Tosu which had expanded south to Ōmura. Okusa was opened on the same day as an intermediate station on the new stretch of track. When the Kyushu Railway was nationalized on 1 July 1907, Japanese Government Railways (JGR) took over control of the station. On 12 October 1909, the track from Tosu through Haiki, Ōmura, Nagayo to Nagasaki was designated the Nagasaki Main Line. On 2 October 1972, a shorter inland bypass route was opened between Kikitsu through Ichinuno to Urakami was opened, which became known as the new line or Ichinuno branch of the Nagasaki Main Line. The section serving Okusa became known as the old line or the Nagayo branch. With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, control of the station passed to JR Kyushu.^[6][7]
