Ironman Heavymetalweight Championship

The Ironman Heavymetalweight Championship (Japanese: アイアンマンヘビーメタル級王座, Hepburn: Aianman Hebīmetaru-kyū Ōza) is a professional wrestling championship created and promoted by the Japanese promotion CyberFight in its DDT Pro-Wrestling (DDT) brand. Open to anyone, regardless of gender or DDT employment status, the championship is defended "24/7", as in any time, anywhere, as long as a referee is there to confirm the win. Because of this rule, not only is the championship winnable regardless of gender or number of individuals (in case of a common pinfall or submission), it is also available to "unconventional" champions such as animals or inanimate objects, with title changes regularly occurring outside of regular shows, often with videos posted on the promotion's social media accounts. The current champion is Unagi Sayaka who is in her eighth reign.

The championship was introduced on the June 29, 2000 TV taping, during which Poison Sawada Black created the title and awarded it to himself. It was created as a parody of the now-defunct WWE Hardcore Championship, which also had a "24/7 rule". The title is often defended during a 10-minute battle royal, with the current holder not being allowed to leave the match until the end of the time limit; as per 24/7 rules, the championship can change hands during, and not only as the result, of the match. Despite its name and similarly titled championships, it is not specific to Iron Man matches.
