What happened: Aoki is booked for Thursday’s co-main event in Osaka. He views the RIZIN appearance as a chance to close the unfinished chapter left after DREAM failed to replace PRIDE.
Why it matters: The bout connects Japan’s current MMA scene to two defining names from its earlier era. At 43, Aoki’s return carries clear historical weight beyond the matchup itself.
By the numbers: Aoki is 43 years old.
What to watch: The next marker is Thursday’s co-main event in Osaka, where Aoki’s return becomes competitive rather than retrospective.
