Mainichi Issho is a Japanese video game developed by BeXide and published by Sony Computer Entertainment for the PlayStation 3 starring the PlayStation mascot Toro Inoue. It ran from November 11, 2006 to 2009 and was replaced by Weekly Toro Station. There was also a version for the PlayStation Portable called Mainichi Issho Portable. Trial versions of both the PSP and PS3 versions can be found on the original Japanese version of Toro! Let's Party!.

After the service ended in 2009, the console version was made inaccessible, although the PSP version is still playable in a limited form. The console version can also be played in a limited form offline through emulation by forcing a PlayStation Network connection, although all its online features are inaccessible.

Mainichi Issho featured a live broadcast service called Toro Station, in which Toro and Kuro presented a news show which covered various topics. Most of what was covered were various new video games for Playstation consoles, but they also covered other subjects like promoting local Japanese businesses or sports and science related news. These broadcasts were delivered on a roughly daily basis, and were moved to Weekly Toro Station after Mainichi Issho's service ended.
