Computer Entertainment Rating Organization
Industry Classification board, Non-profit organization
Founded July 2002
Parent Computer Entertainment Supplier's Association

The Computer Entertainment Rating Organization (CERO) is the organization that rates video games (except PC games such as dating sims, visual novels and eroge) in Japan with levels of rating that informs the customer of the nature of the product and for what age group it is suitable. It was established on July 2002 as a branch of Computer Entertainment Supplier's Association, and became an officially recognized non-profit organization on 2003. Cultural differences between ratings are very common, and games can receive different ratings in different countries. For example, the games God Hand, Metal Gear Solid: Digital Graphic Novel, Shin Megami Tensei: Persona 3, Shin Megami Tensei: Persona 4 and Samurai Shodown: Sen were all rated B by the CERO, which would technically give them T (12+) ratings in North America. However, they were all rated M (17+ - CERO D rating) by the ESRB, a difference of two grades. Some ratings, however, are consistent, such as No More Heroes which is rated M by the ESRB, D by the CERO and 16 by the PEGI. Also, some games may be partially censored to eliminate some of the more mature themes in the games' content, such as the aforementioned No More Heroes.
