History
Daikokuchō Station opened on 21 April 1938 on the southward Namba-Tennōji extension of the Osaka Municipal Subway Line 1 (today's Midōsuji Line). The new Line 3 (today's Yotsubashi Line) reached the station on 10 May 1942 as a single-stop spur to Hanazonochō, making Daikokuchō both an interchange and the Yotsubashi line's starting terminus until the line was extended north to Nishi-Umeda in October 1965. The Midōsuji platform was extended in December 1987 to accept ten-car trains. The station passed to Osaka Metro on 1 April 2018 with the privatisation, and movable platform doors followed in 2021 and 2022.

Notes
Daikokuchō is the only Osaka Metro interchange where two lines share a flat cross-platform layout — same-direction passengers between Midōsuji and Yotsubashi services can simply step across the platform.
