Rating System

Age Rating System

The system is to indicate target ages of potential game players based on content and expressions of computer and video games. It endeavors to indicate age classification marks covering all the computer and video games for household use sold domestically. The system that started on October 1, 2002 is maintained and implemented by Computer Entertainment Rating Organization (abbreviated as CERO) established in June 2002.
An indicated "age classification mark" represents that the game has been reviewed according to the CERO Code of Ethics and that the game includes content suitable for the game players of the indicated age and above. The marks are to be used for informed purchasing decisions. 

1. Scope of Rating

The rating by CERO covers the computer and video games for household use (including cellular phone-type games) sold in Japan. It covers not only main stories but also all the recorded expressions such as hidden commands and tricks.

3. CERO Rating Marks

"CERO rating marks" are grouped broadly into "age classification marks" and "other marks."
 
A. Age Classification Marks
 
Age classification marks include the following five marks. One of the marks is indicated on the left bottom of the game box front, and a corresponding color bar is also shown on the box spine. (Bar colors: black for "A"; green for "B"; blue for "C"; orange for "D"; red for "Z")
Note: Products indicated with the classification marks are being sold, the products having been rated according to the pre-revision criteria. 
"※Pre-Revision Age Classification Mark"
B. Other Marks
 
Other marks include three marks of "Educational/Database," "CERO Regulations-Compatible" used for trial versions, and "Rating Scheduled" used for promotion items that game publishers use for advertisements of their games being created (having yet to be reviewed at this point).
Reminder: 
Irrelevant to CERO rating, cases have recently occurred in which a "rating mark" or a similar mark is indicated on product boxes in the market. Since such conduct confuses people and allows them misunderstand that the game in question has been assigned rating by CERO and infringes the Unfair Competition Prevention Law, please be reminded that such conduct should not be performed.
 

4. Content Icons

The rating mark is indicated on the game box front, and the content icon, on the back. Content icons represent that the age classification decision has been made based on the expressions belonging to one (or more) of the content icons. They are grouped into nine categories.

5. Rating Process

The following is the flow of the steps for reviewing rating to indicating an age classification mark:
 
   1) CERO receives a request of ethics reviewing for a computer and video game from a game publisher. 
 
   2) Numerous raters review expressions, content, etc. of the requester's game. 
* The expression items subjected to reviewing include twenty-four items listed in "2. Expression items to be covered through rating," and each expression item has an upper limit, the expressions and content that exceed the upper limit are specified as "banned expressions," and the computer and video games that include the banned expressions will not be assigned rating.
 
   3) An age classification is determined based on respective evaluating results. 
 
   4) CERO notifies the game publisher of the review result. 
 
   5) The game publisher indicates an age classification mark on the product.

Raters consist of males and females in various occupations, aged from the twenties to the sixties, who are recruited widely from the public and have been trained in advance by CERO. Raters have been registered by CERO and have executed a non-disclosure agreement. It is taken into consideration that there is no bias in raters' attributes such as sex and age in respective reviewing. No raters who are associated with the game industry are registered.
