IWGPヘビー級王座
On June 29, 2007, IGF held its debut show with Lesnar defending the IWGP Heavyweight Championship against Kurt Angle in the main event. Angle defeated Lesnar to win the championship and went on to appear in the American Total Nonstop Action Wrestling (TNA) promotion with the physical title belt. TNA also referred to the title belt as the IWGP Heavyweight Championship in the same manner as IGF, recognizing Angle as the official IWGP Heavyweight Champion. NJPW did not recognize Angle as the IWGP Heavyweight Champion, instead it viewed Angle as the second IWGP 3rd Belt holder.
