The Computer Entertainment Rating Organization(JP) (CERO) is a Japanese video game content rating system used for Nintendo's gaming systems starting with the Game Boy Advance and the Nintendo GameCube. It was established by the Japan-based Computer Entertainment Supplier's Association (CESA)(JP), an organization that Nintendo is a member of.[1]

The CERO does not rate games that contain excessive sexual, violent, criminal, or indecent content.[2][3] In addition to this, Nintendo hasn't allowed these types of games to be developed for their systems long before the CERO's establishment.
