History
Nishiohashi Station opened on 29 August 1997 with the Nagahori Tsurumi-ryokuchi Line's extension from Shinsaibashi to Taisho. The underground station has a single island platform 135 metres long, with one ticket gate at its Taisho end. Platform-edge doors entered service on 15 September 2010, and on 1 April 2018 the station passed to Osaka Metro with the privatisation of the Osaka Municipal Transportation Bureau. The name preserves Nishiohashi, a bridge that once carried Naniwa-suji over the now-buried Nagahori-gawa, and survives in the Nishiohashi intersection where the two thoroughfares meet.
