Key takeaways
Kyoma Akimoto beat Kleber Koike by unanimous decision after three rounds in the main event of RIZIN 54 at the Toyota Arena Tokyo in Koto. The co-main event also went to the scorecards: Shoko Sato beat Patchy Mix after three rounds at bantamweight.
Across the ten bouts that produced a result, six ended by knockout, two by submission and two on the judges' scorecards — eight stoppages in ten fights. Every decision was unanimous: not one result divided the judges.
The quickest finish belonged to Jo Hiramoto, who stopped Ryoma Shishimoto at 1:37 of round one, and five of the eight finishes came inside the opening round. The longest was Yuki Ito's knockout of Alibek Gadzhammatov, 8 minutes and 51 seconds in. End to end, the ten fights filled one hour and 12 minutes of cage time.
Five weight classes were used, featherweight most often with three bouts.
