CERO: 18

Items classified as 18 and Over (Jūhachi-sai ijō taishō) by the Japanese Computer Entertainment Rating Organization (CERO). This was a voluntary advisory only. With the March 2006 system revision, this rating ceased and a new CERO D (17+) rating was introduced alongside the legally restricted CERO Z (18+). Most titles in this legacy classification would meet the new 17+ rating.
