18-year-old prospect Adrian Lee, the younger brother of current ONE two-division champion Christian Lee, has booked his third fight since turning professional.

This time around, Lee faces undefeated fighter Shozo Isojima, who comes into the matchup with a perfect 5-0 record, when they meet at ONE 172, which is scheduled to take place at Saitama Super Arena in Japan on March 23.

ONE officials confirmed the pairing to MMA Fighting on Wednesday.

Coming from a family famous for fighting, Lee is making his own waves in the sport after starting out his career with back-to-back submission wins.

Lee competed twice in 2024 with his brother Christian serving as his primary trainer once his family’s martial arts gym actually closed its doors following the tragic loss of his sister Victoria Lee in 2022. Lee’s older sister Angela Lee previously served as ONE’s strawweight champion but she retired from competition to focus on her non-profit organization focused on mental health.

Now it’s Adrian carrying the torch as he moves forward with his own career in ONE Championship.

As for Isojima, he makes his debut for the promotion when he faces Lee in March as part of ONE’s return to Japan. Isojima has only previously competed for the Gladiator organization in his native country with five straight wins including an impressive 4-0 resume in 2024.

Lee vs. Isojima joins a growing lineup at ONE 172 with a kickboxing match between Takeru Segawa vs. Rodtang Jitmuangnon headlining the card.
