About CERO

Our mission is to enable everyone to purchase and enjoy computer and video games free from concernes about content.
As the technology of game consoles advances and the age brackets of game consumers expand, computer and video games have been diversified both in content and expressions. Given this trend, social requirements have intensified, and a typical requirement is related to the influence that the content of a game may have on young people. To fulfill those social needs, the Computer Entertainment Rating Organization (abbreviated as CERO) was founded in June 2002. CERO is operated independently of any specific corporation or organization for the sake of fairness.
CERO was accredited as a specified nonprofit corporation by the Tokyo Metropolitan Government in December 2003.
