History
Mikawa-Ōno Station opened on 1 February 1923 as a stop on the now-defunct Hōraiji Railway, a private line that ran inland from Ōumi northward along the Une River. On 1 August 1943 the Hōraiji and Sanshin railways were nationalised together with other connecting lines to form the Iida Line of the Japanese Government Railways. Scheduled freight ended in December 1971, and the station was made unstaffed in February 1991. Privatisation on 1 April 1987 transferred it to JR Tōkai. A new mountain-hut-styled station building was completed on 26 February 1996, replacing the original wooden structure that, in its earliest years, housed a railway-operated inn for travellers from Shizuoka.

Notes
The original wooden station building included a railway-operated inn for Shizuoka-side travellers, reflecting heavy use of the line from the east; it stood until the 1996 rebuilding.
