At 2023's Power Struggle, after Will Ospreay had defended the IWGP United States Heavyweight Championship against Shota Umino in the main event, Bullet Club leader David Finlay destroyed both the U.S. belt and Ospreay's custom IWGP United Kingdom Heavyweight Championship belt with a mallet after attacking Ospreay and Umino's former mentor, AEW's Jon Moxley, and a three-way match was scheduled for three men at Wrestle Kingdom 18.[3]
While the match was initially listed as for the United States title, NJPW chairman Naoki Sugabayashi announced at a press conference on November 6, 2023 that the title would be retired and the match would be for a brand new championship.[4] On December 11, at another press conference, he announced the name of the new championship, the IWGP Global Heavyweight Championship.[1][5]
Belt design
The new championship belt was revealed on January 3, 2024. It is set on a white strap, similar to the now-retired IWGP Intercontinental Championship, and features five plates: one center and two set of side plates. The center plate features depictions of lions on each side, the "IWGP" letters in the center, and the words (all in capital letters) "Global" and "Champion" on the top and bottom, respectively; the New Japan logo is also featured on the top. Four gold circles with a ruby in the center are vertically set, two on each side, next to the center plate. The two sets of side plates each feature different parts of the world globe.[6]
Reigns
As of November 8, 2024, there have been three reigns shared among two wrestlers. David Finlay was the inaugural champion, has the most reigns at two, and was the youngest champion, winning it at 30 years old. Nic Nemeth was the oldest champion when he won it at 43 years old.
