History
Nishi-Nagahori Station opened on 16 April 1969 as part of the Osaka Municipal Subway Line 5 (now the Sennichimae Line) between Noda-Hanshin and Sakuragawa. It became an interchange on 29 August 1997 when the Nagahori Tsurumi-ryokuchi Line was extended from Shinsaibashi to Taisho. The Sennichimae Line platform was deliberately built south of the avenue to clear the buried Nagahori-gawa, which gives the station an unusually long transfer corridor and noticeably tall ceilings. Platform-edge doors entered service on the Nagahori Tsurumi-ryokuchi side in September 2010 and on the Sennichimae side in November 2014. The station passed to Osaka Metro at the 2018 privatisation.

Notes
The neighbourhood is the birthplace of Mitsubishi, founded here by Tosa-born Iwasaki Yataro; the Edo-period Tosa-han warehouse district along Nagahori-dori left placenames like Shiragabashi and Katsuozabashi (after Tosa's Mt. Shiraga and katsuo).
