The Yamatoji Line (大和路線, Yamatoji-sen) is the common name of the western portion of the Kansai Main Line.

It starts at Kamo Station in Kyoto Prefecture and ends at JR Namba Station in Naniwa-ku, Osaka.

The oldest section of the Yamatoji Line is between Kashiwara and JR Namba, which opened on May 14, 1889.

The present route was completed on August 21, 1907 when the new line between Kamo and Kizu, replacing the original route via Daibutsu, was opened.

[3][4] Local trains stop at every passenger station.
