The GHC Hardcore Openweight Title was established in April 2004, and its status as an openweight title means that both heavyweights and juniors can compete for the title. The belt was created by Jun Akiyama as his own personal title, and is defined by its unique rules; each title match has a 15 minute time limit, and should the match reach the 15 minute mark the challenger is awarded the title.
