Hankyū Minoo Line

The line is one of the founding routes of the Hankyu network. It was opened in 1910 by the Minoo Arima Electric Tramway, the company that became Hankyu, together with the Takarazuka Main Line; it has always been operated as a branch of that trunk line, and before the Second World War it was sometimes written as the "Minoo Branch Line." The first section, between Ishibashi and Minoo, opened on 10 March 1910, and Sakurai Station followed on 12 April of the same year. At the outset the junction at Ishibashi was built as a triangular (delta) junction and the Minoo terminus as a loop, and trains are said to have run through on a circuit by way of Umeda, Ishibashi, Minoo, Ishibashi and Takarazuka.

The line's small roster of stations was completed early. Makiochi Station, between Sakurai and Minoo, opened on 30 December 1921, bringing the line to its present four stops. No further stations have been added since, and the route has kept the same alignment from Ikeda into the heart of Minoh ever since.

Through running toward central Osaka shaped much of the line's later operating history. A weekday-morning semi-express between Umeda and Minoo was introduced on 1 April 1953, and over the following decades the through services to and from the Takarazuka Main Line were repeatedly recast — semi-express and commuter-semi-express designations were swapped back and forth in timetable revisions of 1997, 2000 and 2003. Safety and infrastructure were modernised in parallel: an automatic train stop (ATS) system entered service on 1 May 1968, and on 24 August 1969 the overhead voltage was raised from 600 V to 1,500 V DC. On 10 March 1978 the whole line was reclassified from a tramway under the Tramways Act to a railway under the Local Railway Act.

A proposed eastward extension never materialised. In December 1961 Hankyu obtained a licence for a new line from Sakurai Station to Senriyama Station on the Senri Line, running east along the Saigoku Kaidō, but the plan was abandoned and the licence surrendered in December 1972, leaving the Minoo Line at its original length.

From the 2010s the link to Osaka was steadily wound down. Station numbering was introduced across all four stops on 21 December 2013. The commuter-semi-express was abolished and folded into the ordinary semi-express in the revision of 21 March 2015, and on 7 July 2018 the remaining semi-expresses, the Umeda-bound through trains and the eight-car in-line shuttles were all discontinued. On 1 October 2019 the junction station was renamed from Ishibashi to Ishibashi-handai-mae.

The last direct trains to central Osaka ran until the timetable revision of 17 December 2022, after which every service became an in-line shuttle confined to the branch, ending the long history of through running to Osaka-Umeda. Most recently, Hankyu introduced one-man (driver-only) operation on the line on 28 March 2026, alongside similar conversions on its Itami and Arashiyama lines, leaving the Minoo Line a compact, self-contained shuttle feeding the Takarazuka Main Line at Ishibashi-handai-mae.
