• JR Nippo Line: Hyuga-Shintomi ⇄ Hyuga-Sumiyoshi

The station opened on 11 September 1920 as Hirose Station on what was then the Railway Ministry's Miyazaki Main Line, the route being redesignated the Nippō Main Line on 15 December 1923. It was renamed Sadowara — adopting the second-generation use of that name — on 1 July 1965, after the original Sadowara Station on the Tsuma Line was renamed Nishi-Sadowara a month earlier. Freight handling ended on 1 February 1984, and the connecting Tsuma Line was abolished on 1 December the same year. The station became unstaffed in November 1986. JR Kyushu inherited it at the 1 April 1987 privatisation, and a JR Freight terminal opened on 31 July 1991, becoming a truck-only off-rail station on 1 April 2006. SUGOCA service began on 14 November 2015.

A solar-panel pilot installed directly on the rails of disused Platform 1 began generating power for station operations on 8 October 2025.
