• JR Nippo Line: Kaizaki ⇄ Kamioka

Saiki Station opened on 25 October 1916 as the new southern terminus of Japanese Government Railways' Hōshū Main Line, originally read "Saeki-eki". It became a through-station on 20 November 1920 when the line was pushed further south to Gōnohara (today Naokawa), and the route was renamed the Nippō Main Line on 15 December 1923. The reading of the station name was officially changed from "Saeki" to "Saiki" on 15 January 1962, with the kanji unchanged. The second-generation station building was completed on 10 June 1979. Control passed to JR Kyushu at the 1987 JNR privatisation. In September 2017 Typhoon Talim flooded the station and disrupted services along the line.

The station's reading was officially changed from "Saeki" to "Saiki" on 15 January 1962, with the kanji left untouched — an unusual purely-phonetic renaming.
