History
Kii-Miyahara Station opened on 11 December 1925 on the Japanese National Railways Kisei West Line in what is now Arida, Wakayama Prefecture. The line through the station became part of a unified Kisei Main Line on 15 July 1959. Freight handling ended on 1 February 1984 and parcels on 14 March 1985. JR West took over at the privatisation of JNR on 1 April 1987. ICOCA service began on 14 March 2020 and the station was fully destaffed from 1 June 2021. The platforms once formed a complex 2-island, 3-track passing layout; the centre line's signals were cut around 2007 and the track and overhead were later removed, leaving two side platforms in use.

Notes
The platform formerly numbered "2" remains visibly missing — when the centre passing track was withdrawn around 2007 the numbering on the timetables was simply left as a gap, and the old wooden station building is still in use.
