Introduction
UFC 23: Ultimate Japan 2. November 19, 1999. Tokyo Bay NK Hall, Urayasu, Chiba, Japan. Kevin Randleman, who most of the MMA world believed had won his title fight against Bas Rutten at UFC 20 only to be denied by the judges, got his second chance. Opposite Pete Williams, the man who had shocked Mark Coleman with a head kick at UFC 17, Randleman went five full rounds and won the Heavyweight Championship on a unanimous decision. Justice, or at least a version of it.
UFC 23 was also historic for ending what the tournament format had been in UFC. A four-man Japanese tournament — the first since UFC 17 — was held to crown a UFC Japan Champion. It was the last one-night tournament the UFC ever ran. The event took place in Japan during the height of PRIDE FC’s dominance there, and represented the UFC’s attempt to stay relevant in the world’s most active MMA market.

🏆 Heavyweight Championship: Kevin Randleman def. Pete Williams — Decision (Unanimous) — R5, 5:00 — Randleman becomes UFC Heavyweight Champion

🌟 Historic: Last one-night UFC tournament ever; UFC Japan vs. PRIDE FC era; Randleman wins title denied to him by judges at UFC 20
Randleman Becomes Champion
The fight opened with an aggressive exchange — Williams landed a combination that put Randleman down early, momentarily flipping the script on a man who had seemed destined for the belt. But Randleman recovered, shot for takedowns, and used his wrestling to control the remaining rounds. The pattern established at UFC 20 repeated: dominant wrestling, top control, ground-and-pound. This time the judges gave it to him. After five rounds, Randleman won by unanimous decision and became the UFC Heavyweight Champion.
For the majority of observers who had watched UFC 20, the result was satisfying. Randleman had looked like the winner against Rutten. The split decision had felt wrong. In Tokyo, the outcome was not in question. He would go on to make one successful title defence before losing the belt at UFC 28.
The Last UFC Tournament
The four-man UFC Japan tournament was the first to feature Japanese fighters in a structured format and was designed to produce a UFC Japan Champion. Kenichi Yamamoto defeated Daiju Takase in the semi-final and then beat Katsuhisa Fujii with a kneebar in the final to claim the title. It was the first UFC tournament since UFC 17 in May 1998 — and the last the promotion ever ran. The format that had defined the UFC since its first event in November 1993 made its final appearance here.

Legacy & Impact
UFC 23 is a transition point in multiple directions simultaneously. The tournament format — the UFC’s founding structure, the framework that had produced some of the sport’s most dramatic early moments — ended here. The heavyweight championship found its rightful occupant, correcting what most of the sport had seen as a judging error at UFC 20. And the UFC was competing in Japan against PRIDE FC, a promotion that had captured the country’s MMA enthusiasm with larger productions and bigger stars.
Randleman’s title run would be brief. He made one successful defence against Pedro Rizzo at UFC 26, but lost the belt to Randy Couture at UFC 28 via TKO. The heavyweight division was entering one of its most turbulent periods. UFC 23 captured a brief moment of clarity — the right man won, on a format that had reached its end.
