Shinya Aoki is retiring from mixed martial arts, and he has a date and a name for the last one. Aoki announced on X on Nov. 8, linking a post titled with the words “Aoki Shinya retirement,” that he will end his MMA career after facing Taisei Sakuraba on New Year’s Eve. RIZIN confirmed the matchup the same day, billing it officially as Aoki’s retirement bout.
The fight lands on Super RIZIN 6 on Thursday, Dec. 31, at Vantelin Dome Nagoya. RIZIN lists it as a three-round fight under its MMA rules, five minutes a round, at a 71.0 kg limit (roughly 156.5 pounds). Doors are scheduled to open at 11:00 a.m. local time, with the show starting at 1 p.m. The event carries a subtitle built around gekokujo, the old Japanese idea of the lower rank overthrowing the higher one. Putting Aoki in a retirement fight on that card tells you exactly what role the promotion has written for the other guy.
That other guy has a familiar surname. Kenji Osawa pointed out on X that Aoki’s opponent is Sakuraba’s son, and added that the older crowd wants to see it. Former fighter Katsunori Kikuno reposted Aoki’s announcement and wrote that another era is ending.

Aoki’s career runs past two decades, and the timing of the news hit an oddly fitting week. Two days before the announcement, ONE Championship was promoting Christian Lee’s lightweight title defense against Tye Ruotolo by replaying the night Lee first won the belt from Aoki. The other piece of Aoki history floating around this weekend came from a Fedor Emelianenko story on Essentially Sports, which recalled their 2009 grappling exhibition at Tokyo’s Differ Ariake Arena. Fedor won that one by Achilles lock, which is a strange sentence to type about a man whose whole reputation was built on finishing people from the bottom.

Aoki had been writing about RIZIN as recently as Nov. 8, posting a preview of RIZIN.55, which he described as the last event before New Year’s Eve. In that same post he mentioned that his purse from RIZIN’s September event arrived earlier than scheduled, and that he was grateful for it.
My take: this is the right way to book a farewell. Aoki gets a name with weight in Japanese fight history, RIZIN gets its generational handoff story, and the fight is short enough (three rounds, five minutes each) that Aoki’s path is obvious. He needs to get his hands on Sakuraba early, drag it to the mat, and start hunting limbs before the legs and lungs of a younger fighter become the story. If Sakuraba keeps it standing through the first five minutes, the gekokujo poster starts looking prophetic. If Aoki gets a grip on a heel or an arm in Round 1, Nagoya gets one more of the finishes that made him. The answer comes Dec. 31.
