The 2.7-kilometre (1.7 mi) line has only two stops, and only operates during morning and evening, and mainly serves commuters to the Mitsubishi Heavy Industries and Mitsubishi Electric factories in the Wadamisaki industrial area of Kobe.

Although the line is officially part of the Sanyo Main Line, there is no regular through service between the branch and the main line, and Wadamisaki Branch trains depart from a separate platform at Hyogo.

Because the line has no intermediate station and Wadamisaki Station is unmanned, all fare collection is conducted at Hyogo.

The line makes just two daily roundtrips on weekends, with additional trips for events at Noevir Stadium, the home stadium of J-League football club Vissel Kobe.

There is also a spur to the now-defunct Hyōgo Kaigan Line (operated 1910–1984) about 1 km away from Hyōgo Station and a link to the Mitsubishi Heavy Industries shipbuilding facility at Kobe Shipyard just after Wadamisaki Station.
