Stepping onto the global stage of ONE Championship for the first time, Japanese grappling sensation Kenta Iwamoto isn't just looking to make an entrance—he's coming for revenge. His debut at ONE Fight Night 42 this April 10th is a highly anticipated rematch against Canadian standout Dante Leon, and Iwamoto has vowed to turn the tables in their welterweight submission grappling clash.

The fight, set for the iconic Lumpinee Stadium in Bangkok, airs live in U.S. primetime on Prime Video. For Iwamoto, a three-time ADCC Asia and Oceania Trials Champion, this is more than a debut; it's a chance to settle a score from their 2023 meeting at the AIGA Champions League, where the more experienced Leon secured a submission victory.

That loss sparked a transformation. Iwamoto has since embarked on a global campaign, sharpening his skills and building immense momentum. Training with teams like IGLOO Brazilian Jiu-Jitsu and B-Team, he has evolved into a more complete and confident athlete, consistently testing himself against top-tier competition.

"When I first fought Dante, I wasn't as experienced as I am now," Iwamoto told ONE Championship. "I've been performing well, fighting big names, and getting comfortable forcing my style on my opponents. That's the difference."

His game plan is clear and carries the confidence of a fighter who has done the work. "I want to take him into deep waters," Iwamoto stated, outlining a strategy to break Leon's spirit through relentless pressure and technical prowess. This mindset reflects the dedication of an athlete who has lived on the mats, refining every detail of his craft for this exact moment.

For fans of combat sports and the technical chess match of high-level grappling, this rematch is a must-watch. It's the story of a motivated debutant aiming to prove his evolution against a proven veteran, all under the bright lights of ONE Championship.
