The Umeda - Juso section was opened in 1910 as part of the Hankyu Takarazuka Line.

The Juso - Oji-Koen section opened as a 1435mm gauge line electrified at 600 V DC in 1920.

As a branch of the main line, the 1 km (0.62 mi) line between Oji-Koen Station and Kamitsutsui Station continued to provide a connection to the Kobe tram network until 1941.

The Kobe Main Line was damaged by the Great Hanshin earthquake in January 1995.

The project, which includes a bicycle parking lot and reconstruction of the surrounding roads, is expected to cost ¥6 billion.
