About CERO
Our mission is to enable everyone to purchase and enjoy computer and video games free from concerns about content.
With the advancement of home video game console technology and the expansion of the age range of game users, as the content and expression of game software have become more diverse, there has been an increasing need to consider the impact these games have on young people. In June 2002, in response to such social demands, the Computer Entertainment Rating Organization (CERO) was established as an institution to operate and implement an age-based rating system for game software. In November 2003, CERO was certified as a specific nonprofit corporation (NPO) by the Tokyo Metropolitan Government and continues to operate today.
The organization conducts age-based rating reviews in a fair and impartial manner, operating independently without reliance on specific companies or organizations.
