List of Ironman Heavymetalweight Champions
The Ironman Heavymetalweight Championship is a professional wrestling championship created and promoted by the Japanese promotion DDT Pro-Wrestling. 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, 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. It was created as a parody of the defunct WWE Hardcore Championship, which also had a "24/7 rule".
The championship was introduced on the June 29, 2000 TV taping, during which Poison Julie Sawada created the title and awarded it to himself, only to lose it in under three minutes after Mitsunobu Kikuzawa attacked him with the belt and successfully pinned him.
