ONE Championship Announces Two World Title Fights For Tokyo And Bangkok

ONE Championship has confirmed two World Title fights for two separate events, with Joshua Pacio and Regian Eersel both putting their gold on the line before the year is out.

First up, the Philippines' Joshua Pacio makes his latest defense of the ONE Strawweight MMA World Title against Keito Yamakita at ONE SAMURAI 5 on November 18, live from Tokyo.

Then, two-sport ONE World Champion Regian Eersel defends his ONE Lightweight Muay Thai World Title against a familiar face in George Jarvis at The Inner Circle 33 on October 2, streaming via live.onefc.com from Bangkok, Thailand.

Pacio's reign is one for the history books. Eight championship wins. A 24-5 career MMA record with 19 finishes. A 15-5 ONE record with 10 finishes. These are numbers that speak for themselves, and the Lions Nation MMA product is showing no signs of slowing down.

Yamakita is the challenger most equipped to change that. The 30-year-old Japanese wrestler carries a 13-1 career record with six finishes and a 6-1 ONE record into the Tokyo title fight, with five consecutive victories building an unstoppable wave of momentum.

The story in Bangkok centres on a rematch that has been simmering since August 2025. Eersel, 33, is a force of nature in the lightweight Muay Thai division, and the numbers behind his reign are staggering. The Sityodtong Amsterdam product carries a 65-5 striking record and a 14-1 ONE slate into the rematch.

For Eersel, October 2 is simply another opportunity to remind the lightweight striking world that there is no one in his class.

Jarvis, 26, carries that first-fight result as motivation rather than a burden. The Lumpini Crawley product, standing 6 feet with a 28-5 striking record and a 6-2 ONE slate, has responded to the setback exactly as a title contender should, stringing together two victories over former title challengers to earn his second crack at Eersel's Muay Thai crown. Now, he arrives in Bangkok with a specific point to prove.
