The Naniwasuji Line (なにわ筋線, Naniwasuji-sen) is an underground heavy rail line scheduled to open in spring 2031, which will run north-south through central Osaka, primarily under the avenue Naniwasuji. It has long been pursued by West Japan Railway Company (JR West) and Nankai Railway in order to connect the JR Yamatoji Line (Kansai Main Line) and Nankai Main Line with Shin-Osaka Station, greatly enhancing both companies' connections to Kansai International Airport and Wakayama Prefecture. As of 18 March 2023, the tracks through the northern terminus at Osaka Station and adjoining underground platforms were opened for the Haruka, Kuroshio, Mahoroba and Rakuraku Yamato limited express services as well as ordinary trains on the Osaka Higashi Line.
