Callum Newman Makes History as Youngest IWGP Heavyweight Champion at Sakura Genesis

History was rewritten at Sumo Hall this Saturday during NJPW Sakura Genesis, as Callum Newman captured the IWGP Heavyweight Championship. At just 23 years traditional, Newman has officially grow the youngest champion in the title’s history, marking a seismic shift in the landscape of New Japan Pro-Wrestling.

A Historic Night at Sumo Hall

In the main event of Sakura Genesis 2026, Callum Newman faced off against Yota Tsuji, who had held the championship since Wrestle Kingdom 20 in January. The match was a high-stakes clash that culminated in Newman scoring the pinfall victory after connecting with the Prince’s Curse and the “make way.”

Newman’s path to victory was not without tension. During the bout, Newman attempted to use a steel chair on Tsuji, but was stopped by his mentor, Will Ospreay. Newman eventually secured the win after blasting Tsuji with a “Hidden Blade.” Following the match, Ospreay—who wrestled earlier in the evening—was the first to embrace Newman and personally place the IWGP Championship around his waist.

In a short post-match promo, the new champion told the crowd that there was no longer any doubt about his capabilities, punctuating the moment by telling the audience to “kiss the crown.”

The Ascent of the United Empire’s New Leader

Newman’s victory is the culmination of a rapid rise within NJPW. According to biographical records, Newman began his training at the age of seven under his grandfather, Toni Granzi, a renowned heel wrestler from the 1950s and 1960s. After a hiatus to focus on football, he debuted professionally in 2018 under the mentorship of Will Ospreay, gaining experience in the British independent circuit through promotions like Progress Wrestling, Revolution Pro Wrestling (RevPro) and London Lucha League (LLL).

After signing with NJPW in 2023, Newman joined the United Empire. He ascended to the leadership of the stable in 2025 following the departures of TJP and Ospreay. His momentum peaked in 2026 when he became the youngest wrestler to ever win the New Japan Cup, a victory that paved his way to the IWGP Heavyweight Championship.

During his championship win, Newman was accompanied by the full force of the United Empire, with members Jakob Austin Young, Jake Lee, Francesco Akira, HENARE, and Great-O-Khan all sporting suits for the occasion.

Chaos and Challenges: What’s Next for the Champion?

The celebration was quickly interrupted by a series of unexpected events that set the stage for Newman’s first reign.

The Return of Gabe Kidd

Immediately following the main event, a hooded figure appeared and attacked the former champion, Yota Tsuji, with a piledriver. The assailant was revealed to be Gabe Kidd. Whereas Shingo Takagi attempted to make the save, Kidd landed a punch before exiting the area.

Shingo Takagi Steps Up

Following the chaos, Shingo Takagi recovered and crossed paths with the new champion, officially issuing the first challenge for the IWGP Heavyweight Championship.

Inter-Promotional Hints

Adding to the intrigue, Will Ospreay requested a private conversation with Newman backstage. This interaction appeared to hint that Ospreay may require assistance in AEW, where he has been facing a “numbers game” played by Jon Moxley and the Death Riders.
