• JR Nippo Line: Shitanoe ⇄ Kami-Usuki

Kumasaki Station opened on 15 August 1920 as an intermediate stop on the existing Hōshū Main Line, opened by Japanese Government Railways through the city of Usuki, Ōita. The line was renamed the Nippō Main Line on 15 December 1923. Freight handling ended on 1 October 1962, and parcel handling on 1 November 1984, when the station was outsourced to a third-party contractor. After JNR's 1987 privatisation, JR Kyushu inherited the station. The station was destaffed on 14 March 2015 as part of JR Kyushu's cost-reduction programme ahead of its 2016 stock-market listing. The station retains its original wooden building from the 1920 opening.

The wooden station building still in use today dates from the 1920 opening — over a century old.
