346 Production (346プロ Mishiro Pro) is a fictional talent agency featured in the Cinderella Girls anime and THE iDOLM@STER Cinderella Girls Gravure For You!. It is a large and well-established talent agency- even including its own filming studio- with many actors, singers, and other talents. At the time the anime starts, it has produced many idols.

- 346 Production is a product of the 2015 anime continuity since the mobile game (and the Cinderella Girls brand to an extent) did not have a de facto production agency and relies on user-named Production clan.
- It is heavily implied and speculated that the U149 anime's talent agency is 346 Production, as a cafe named "Mishiro Cafe" appears in Episode 10. 346 Production itself is never mentioned in-name.
- While it has yet to be confirmed, it is assumed that most of the idols currently in the Cinderella Girls mobile game are part of this agency.
- 346 Production's logo appeared on Ranko's [Nation Blue] SR background in Starlight Stage, one of few instances where 346 Production made appearance outside of the anime continuity and the G4U games.
- 346 Production is the first agency in the series to not focus on idols. It is also the first to have divisions for other talents.
- 346 is read as "Mishiro", meaning "beautiful castle".
- The Gravure For You! series was the first game in THE iDOLM@STER series to label the cast from THE iDOLM@STER Cinderella Girls as members of 346 Production.
- In addition to filming and photo studios, 346 Production also has a dormitory off-site for idols who don't live in Tokyo. This is a nod to the Cinderella Girls mobile game, where extra idols can be "stored" in dorms.
- The official color hex code for the 346 Production logo is #1B1B1B.
