Adrian Lee, 18, Scheduled for Third Pro Fight Against Undefeated Opponent at ONE’s Japan Event in March

Adrian Lee, the 18-year-old rising star in mixed martial arts and younger sibling of two-division ONE champion Christian Lee, is preparing for his third professional bout. Lee will face off against the undefeated Shozo Isojima, who boasts a flawless 5-0 record, at ONE 172. The event is set to take place on March 23 at the Saitama Super Arena in Japan.

Lee, hailing from a family renowned in the fighting world, has been making his own mark in the sport. He began his professional career impressively with two consecutive submission victories. In 2024, Lee competed twice, with his brother Christian acting as his primary coach following the closure of their family’s martial arts gym after the tragic loss of their sister Victoria in 2022.

The young fighter is now carrying on the family legacy in ONE Championship. His older sister, Angela Lee, formerly held the ONE strawweight title but has since retired to focus on a mental health non-profit organization.

Isojima, Lee’s opponent, will be making his debut in ONE Championship. The Japanese fighter has previously competed exclusively in the Gladiator organization in his home country, accumulating five straight wins, with an impressive four victories in 2024 alone.

The Lee vs. Isojima matchup adds to the growing card for ONE 172, which will be headlined by a kickboxing bout between Takeru Segawa and Rodtang Jitmuangnon.
