History
Yotsubashi Station opened on 1 October 1965 as part of the Osaka Municipal Subway Line 3 (now the Yotsubashi Line) extension from Daikokucho to Nishi-Umeda. On 11 December 1996, when the Tsurumi-ryokuchi Line (later the Nagahori Tsurumi-ryokuchi Line) reached Shinsaibashi, the two stations were linked inside the paid fare zone and have since been treated as the same station for fare purposes. The Osaka Municipal Transportation Bureau was privatised on 1 April 2018, transferring the station to Osaka Metro, and platform-edge doors entered service on 24 February 2024.

Notes
The street name uses the hiragana "tsu" while the station name uses katakana "tsu" — a discrepancy said to date to the era when the city's road bureau and its electric bureau filed different transliterations with the supervising ministry.
