Its official name is Rapid Electric Tramway Line No. 6 (高速電気軌道第6号線), while the Osaka Municipal Transportation Bureau refers to it as Osaka City Rapid Railway Line No. 6 (大阪市高速鉄道第6号線), and in MLIT publications, it is written as Line No. 6 (Sakaisuji Line) (6号線(堺筋線)). The Sakaisuji Line also has through services to the Hankyu Railway Senri Line and Arashiyama Line from Tenjimbashisuji Rokuchōme Station.[1][2] Station numbers are indicated by the letter "K".

The Sakaisuji Line was first envisioned in the Urban Transportation Council Report No. 3 (1958) as an underground line running from Tenjimbashisuji Rokuchōme to Tenma via Sakaisuji and Dobutsuen-mae, and it was to be operated by Hankyu Railway. In 1963, the Urban Transportation Council Report No. 7 (1963) recommended that the southern terminus of the Sakaisuji Line be at Tengachaya instead of Tenma. Later unrealised plans for the Sakaisuji Line included two separate extensions to Nakamozu and Sugimotochō, and at one point it was envisioned that through-services between the Hankyu Railway and Nankai Railway would be realised by connecting them together with the Sakaisuji Line through the use of dual-gauge tracks, however that plan was abandoned due to the different electrification systems used by Hankyu and Nankai.[4]

The line opened on December 6, 1969, between Tenjimbashisuji Rokuchōme and Dōbutsuen-mae. The line was extended from Dōbutsuen-mae to Tengachaya on March 4, 1993, as a metro-based replacement of the former Nankai Tennoji Branch Line which closed at the same time.
