History
Ōmi Station opened on 23 September 1900 as the new northern terminus of the Toyokawa Railway, which had been extending north from Toyohashi since 1897. The station became a railhead for travellers bound for the Oku-Mikawa, southern Shinano and northern Tōtōmi hills. In March 1903 it was renamed Nagashino after a placename across the river. The Hōraiji Railway adopted it as its starting point in 1923, and in August 1943 both private companies were nationalised into the Iida Line, restoring the original name Ōmi. The current station building dates from August 1969, freight handling ended in 1984, and the 1987 JNR break-up transferred operations to JR Central. TOICA acceptance began on 15 March 2025.

Notes
For most of its first half-century the station was called Nagashino — the original name Ōmi was dropped in 1903 to use a placename from across the Toyokawa River, and only the 1943 nationalisation restored it.
