The Nankai Main Line (南海本線 Nankai Honsen?) is one of the two main railway lines of Japanese private railway company Nankai Electric Railway, together with Kōya Line. The route is from Namba Station in south downtown of Osaka to Wakayamashi Station in Wakayama via Sakai, Izumiōtsu, Kishiwada, Kaizuka, Izumisano, Sennan, Hannan and Misaki municipalities. The proper name is with the company's name, "the Nankai Main Line", not simply "the Main Line" often seen in other Japanese private railways. Lines of the Nankai Main Lane and the connecting lines excluded the Kōya Line and the Airport Line are named generically "the Nankai Line (南海線 Nankai Sen?)". The line is shown with a pictogram of waves, or distinguished with blue from conifer or green Kōya Line.

Trains are operated from Wakayamashi to Hagurazaki in the midnight. Passes Imamiyaebisu and Haginochaya stations due to absence of platforms on the tracks of Nankai Main line. Those stations are served by Locals of Kōya Line.
In Japanese railway operation, "Futsū" (literally "ordinary, normal") and "Kakueki Teisha" (literally "train that stops at every station", "Kakutei" for short) are used interchangeably for trains that stop at every station. On the Nankai Railway alone, however, the two words are used for different classes of train. The former is for Locals of Nankai Main Line that do not stop at the above two stations, while the latter is for Kōya Line trains that do stop there, true to the meaning of the Japanese name of the service class.


  • S: Trains stop.
  • S*: rapi:t α trains pass, β trains stop.
  • s: Trains stop in the off-peak hours from January 1 until 3 every year.

One of the oldest private railway lines still existing, the Nankai Main Line was opened in 1885 by Hankai Railway (阪堺鉄道 Hankai Tetsudō?) (separate from the present-day Hankai Tramway) between Namba and later abandoned Yamatogawa stations with 2 ft 9 in (838 mm)[1] gauge and steam motive power. Extension was made in 1888 to Sakai. In 1897 the then separate Nankai Railway opened between Sakai and Sano (present-day Izumisano). In 1897 Hankai regauged, in 1898 they merged with Nankai Railway. The present stretch was completed in 1903 to Wakayamashi Station. Electrification was begun in 1907 on the section from Namba to Hamaderakōen, and was completed in 1911.
