History
Uchinomaki opened on 25 January 1918 as an intermediate stop when Japanese Government Railways extended the Miyaji Light Rail Line from Higo-Ōzu east to Miyaji. The route became part of the through Hōhi Main Line on 2 December 1928, after the western extension from Ōita met it at Tamarai. Freight handling ended on 1 October 1971 and the station became unstaffed on 30 November 1983. JR Kyushu inherited the station on 1 April 1987. The wooden ticket-hall building was badly damaged by the 2016 Kumamoto earthquakes; JR Kyushu judged it unsafe and demolished it from 3 October 2016. The section between Higo-Ōzu and Aso through Uchinomaki reopened on 8 August 2020.

Notes
The 1945 station building was burnt out in an air raid on 27 July of that year, and the wartime replacement itself stood until the 2016 Kumamoto earthquakes left it unsafe enough to demolish.
