History
Nagai Station opened on 18 July 1929 as Rinnanji-mae Station on the newly inaugurated Hanwa Electric Railway between Hanwa-Tennoji (today's Tennoji) and Izumi-Fuchu. Through the wartime industry reorganisation it became Nankai Yamate Line on 1 December 1940, then was nationalised on 1 May 1944, renamed Nagai, and absorbed into the Hanwa Line. The Osaka Municipal Subway Midosuji Line Nagai Station opened on 1 July 1960 as part of the Nishitanabe–Abiko extension. JR West inherited the JR station on 1 April 1987. The Hanwa Line up platform was elevated on 16 October 2004 and the down platform on 21 May 2006, eliminating the previous level crossings. The subway operator became Osaka Metro at the 1 April 2018 privatisation, and platform-edge doors entered service on 26 June 2021.

Notes
The Midosuji Line platform at Nagai was built wider than other line stations to handle match-day crowds for Yanmar Stadium Nagai, home ground of J-League side Cerezo Osaka.
