The World Heavyweight Championship is a professional wrestling world heavyweight championship in the Japanese promotion Pro Wrestling Zero1. It is Zero1's top singles title. It was first introduced on December 15, 2007 when Zero1 ended their relationship with the AWA Superstars of Wrestling. The AWA Superstars of Wrestling Champion at the time, Masato Tanaka, was then recognized as the first Zero1 World Heavyweight Champion.[1] To this day, Zero1 continues to use the AWA title belt, which reads "AWA World Heavyweight Wrestling Champion", to represent their world heavyweight championship.[2]

There have been a total of 21 recognized champions who have had a combined 34 official reigns. The current champion is Go Shiozaki who is in his first reign.
