History
Morinomiya Station opened on 21 April 1932 as a new stop on the Japanese Government Railways Jōtō Line between Tamatsukuri and the former Nekoma signal box. The station building was severely damaged in the Osaka air raid of 24 July 1945. In 1961 the Jōtō Line was absorbed into the new Osaka Loop Line, and the JNR site passed to JR West on 1 April 1987. A Chūō Line subway station opened beneath in 1967 as that line's eastern terminus, with the Nagahori Tsurumi-ryokuchi Line arriving in 1996. A subway-station renewal completed on 11 April 2025 follows a "Forest" design concept.

Notes
Since 2014 the JR platforms have used the American folk song "The Bear in the Forest" as a departure melody, riffing on the "mori" (forest) in the station name.
