History
Dainichi Station opened on 8 February 1983 as the new northern terminus of the Tanimachi Line, extended from Moriguchi. The Osaka Monorail (then Osaka Kōsoku Railway) Main Line reached it on 22 August 1997, making Dainichi an interchange. The adjacent Sanyo Electric plant closed in September 2001 and the site was redeveloped, with a new station forecourt opening in April 2004 and the AEON Mall Dainichi opening alongside in 2006; a second monorail concourse was added at the second-floor level to connect to the mall. Tanimachi Line operations transferred from the Osaka Municipal Transportation Bureau to Osaka Metro on 1 April 2018. Platform-edge gates were activated on the monorail in February 2021 and on the Tanimachi Line in November 2025.

Notes
When the Tanimachi Line was extended to Moriguchi in 1977 the Dainichi depot and the lead tracks for a future station were already built, so when the line was finally pushed through to Dainichi in 1983 only a small amount of finishing work was needed to open the station.
