Hankai Line

The line was built by the original Hankai Electric Tramway, which received a licence under the Tramway Ordinance on 28 December 1909 and opened its first section, from Ebisuchō to Ichinochō (present-day Ōshōji), on 1 December 1911. Construction southward followed quickly: the Ichinochō–Shōrinjibashi (present-day Goryōmae) section opened on 5 March 1912 and the Shōrinjibashi–Hamadera section on 1 April 1912, and on 30 November 1912 the short extension on to Hamadera-kōen completed the line. Because the route paralleled the Nankai Railway (today's Nankai Main Line) along its whole length, the two companies competed fiercely for the pilgrims bound for Sumiyoshi Taisha and the excursionists heading to Hamadera Park.

On 21 June 1915 the Hankai Electric Tramway was absorbed by the Nankai Railway and the route became Nankai's Hankai Line. The little Hamadera-ekimae–Hamadera-kōen extension was suspended on 22 December 1916 and abolished on 15 March 1917. The competition resumed in a new form between 1927 and 1935, when a rival operator, the Hankai Electric Railway (the "new Hankai"), laid a parallel line; that line was later bought by the City of Osaka to become the Osaka City Tram's Hankai Line, which was itself dismantled in stages between 1944 and 1968.

Wartime and postwar consolidation reshaped the line's ownership. On 1 June 1944 the Kansai Kyūkō Railway and the Nankai Railway merged to form the Kinki Nippon Railway (Kintetsu), and the line passed to that company's Tennōji business bureau; several stops were closed or suspended around the same time. On 1 June 1947 the former Nankai Railway lines were split off again into the newly established Nankai Electric Railway, and the Hankai Line became one of its Osaka Tramway Lines. In 1957, the widening of the Daidōsuji boulevard in Sakai was accompanied by the relocation of the Ayanochō–Goryōmae track to its present alignment.

On 1 December 1980 the Hankai Line, together with the Uemachi Line, was hived off from Nankai Electric Railway to a newly created subsidiary that revived the Hankai Electric Tramway name — the company that operates the line today. Under Nankai the two tram routes, along with the since-closed Hirano Line, had been grouped together as the Osaka Tramway Lines.

In later years through services were progressively scaled back. From 4 July 2009 most trams ceased to run the full length of the line; service was reorganised into an Ebisuchō–Abikomichi pattern and a Tennōji-ekimae–Abikomichi–Hamadera-ekimae pattern operated jointly with the Uemachi Line, so that passengers travelling the whole way now change at Abikomichi. From 2 February 2013 the last remaining peak-hour through trains between Ebisuchō and Hamadera-ekimae were withdrawn, and all Ebisuchō departures came to terminate at Abikomichi. The Sakai section south of Abikomichi had meanwhile become financially precarious: in 2003 Hankai had even proposed abolishing it, but the City of Sakai chose to support its survival, and in 2010 the two sides reached a basic agreement to keep the Sakai segment running.

The line has accumulated its share of incidents and milestones. On 4 October 1990 the station building at Minamikasumichō (today's Shin-Imamiya-ekimae) was set on fire during a riot in the Kamagasaki district of Nishinari, halting Hankai Line trams until the following day. The stop was renamed Shin-Imamiya-ekimae on 1 December 2014, and a new stop, Ishizu-Kita, opened on 1 February 2015. In 2018 the line's track, rolling stock and Yamato River bridge were recognised as part of a Civil Engineering Heritage of Japan by the Japan Society of Civil Engineers, and on 1 February 2020 the Ebisuchō terminus was moved about 100 metres south to a new building. As Osaka's last surviving street tramway, the Hankai Line today blends slow running through the streets of Sakai with brisk, almost suburban operation on its reserved southern track.
