History
JR Namba Station opened on 14 May 1889 as Minatomachi ("port-town") Station, the western terminus of the Osaka Railway's first segment to Kashiwara. Through Kansai Railway control it was nationalised in 1907 and became the inaugural stop on the Kansai Main Line. The site was relocated about 200 metres southwest on 28 December 1989 and renamed JR Namba on 4 September 1994, the same day Kansai International Airport opened — the first JR Group station to bear the "JR" prefix. A continuous grade-separation project moved the platforms underground on 22 March 1996. By 2031 the planned Naniwasuji Line is to extend the tracks north to Osaka Station.

Notes
JR Namba was the first JR Group station to incorporate the company prefix into its formal name, and it remains the only Japanese station whose official name begins with the Latin letters "JR" — joined by JR Kaizuka, scheduled to open on the Kagoshima Main Line in 2027.
