The IWGP World Heavyweight Championship (IWGP世界ヘビー級王座, IWGP Sekai hebī-kyū ōza) is a professional wrestling world heavyweight championship owned by the New Japan Pro-Wrestling (NJPW) promotion. "IWGP" is the acronym of NJPW's governing body, the International Wrestling Grand Prix (インターナショナル・レスリング・グラン・プリ, intānashonaru resuringu guran puri).[1] The championship was created on March 1, 2021 by the unification of the IWGP Heavyweight Championship and the IWGP Intercontinental Championship. The current champion is Tetsuya Naito, who is in his first reign.


The inaugural champion was Kota Ibushi.

In 2019, when he was IWGP Intercontinental Champion, Tetsuya Naito declared his intention of making history by becoming the first to hold the IWGP Heavyweight Championship and the Intercontinental Championship at the same time.[2] By the end of the year, Jay White, who had won the Intercontinental Championship from Naito, and Kota Ibushi, who was the next challenger for the Heavyweight Championship, also expressed the same desire. After a fan vote, it was decided that Naito, White, Ibushi, and Heavyweight Champion Kazuchika Okada would compete at Wrestle Kingdom 14 on January 4–5, 2020, where one would end up with both titles.[3] Naito achieved the feat to become the first "Double Champion" and the two titles were defended together since (apart from one time). During 2020, Naito said his original intention was for the titles to be defended separately. He requested for this, or otherwise for the titles to be unified, but no change happened.[4]

After Ibushi won the titles from Naito at Wrestle Kingdom 15 on January 4, 2021, he expressed his desire for the titles to be unified.[5] On March 1, 2021, with Ibushi still champion, the unification of the titles to create the new IWGP World Heavyweight Championship was officially announced, with Ibushi as the inaugural World Heavyweight Champion. After the announcement, Ibushi, who was scheduled to face El Desperado at the NJPW 49th Anniversary Show on March 4, 2021 in a non-title match, requested for the match to be for the Double Championship.[6] His request was granted with the title unification delayed until after the match, of which the winner would be final Double Champion and, therefore, the inaugural World Heavyweight Champion.[7] Ibushi won the match.[8]

With the announcement of the new championship was the announcement of a new championship belt.[5] Until the new belt was ready, Ibushi continued to hold the old IWGP Heavyweight and IWGP Intercontinental Championship belts. The new belt was eventually revealed and presented to the champion Ibushi in a presentation ceremony on March 30, 2021.[9] Its design incorporated the past belt designs of the two old titles.[10]
