Reigning ONE Flyweight MMA World Champion Yuya Wakamatsu will defend his crown against current strawweight king Joshua Pacio in a champion versus champion showdown at ONE 173: Superbon vs. Noiri on Saturday, November 16, at Ariake Arena in Tokyo, Japan.
The 30-year-old Japanese titleholder reflected on the career-defining moment when he captured the vacant flyweight belt by knocking out multiple-time champion Adriano Moraes in the first round at ONE 172 in March 2025. Wakamatsu described it as the best moment of his life, and now, he looks to make another lasting memory in just a few weeks.
