• Nishitetsu Tenjin Omuta Line: Inuzuka ⇄ Hatchomuta

Ōmizo opened on 1 October 1937 in present-day Ōki Town, Mizuma District, on what is now Nishitetsu's Tenjin Ōmuta Line. The station building was rebuilt in 1966, and the Mizuma–Ōmizo section was double-tracked on 15 January 1997. nimoca contactless ticketing began on 18 May 2008, station numbering was introduced on 1 February 2017, giving the station the code T35, and centralised station management took effect on 1 April 2021, leaving Ōmizo unstaffed throughout the day. The station today consists of a single island platform with two tracks at ground level, and is one of only two Tenjin Ōmuta Line stations located outside a city.

Ōmizo is one of only two stations on the Tenjin Ōmuta Line that sit in district (gun) territory rather than a city; the other is its neighbour Hatchōmuta.
