NWA World Heavyweight Championship
On March 16, 2013, Conway defeated Kahagas to win the National Wrestling Alliance (NWA) World Heavyweight Championship. Through NWA's working relationship with New Japan Pro-Wrestling, Conway appeared via video at New Japan's March 23 event announcing that he would be taking part in the promotion's April 7 Invasion Attack event. He was then challenged to a match for the NWA World Heavyweight Championship by Satoshi Kojima. Conway made his debut appearance for New Japan on April 5, when he, accompanied by NWA president Bruce Tharpe, had an in-ring confrontation with Kojima. Two days later, Conway defeated Kojima, following interference from Tharpe and fellow NWA wrestler Jax Dane, to retain the NWA World Heavyweight Championship. On April 20, Conway successfully defended the NWA World Heavyweight Championship against Chris Masters in Houston, Texas, after which he was presented a new title belt. On June 22, Conway returned to New Japan at Dominion 6.22, where he successfully defended the NWA World Heavyweight Championship against Manabu Nakanishi.
