The fight
Sixteen thousand spectators filled Tokyo’s Kuramae Kokugikan to see an unbeaten Japanese challenger who had stopped 16 of his 18 professional opponents. They instead witnessed the measured destruction of that record, as the taller and more experienced champion retained his WBA and Ring featherweight titles by knocking Royal Kobayashi out in the fifth round.
Alexis Arguello arrived in Japan with a record of 40 victories and four defeats. The Nicaraguan had taken the WBA championship from Ruben Olivares with a thirteenth-round knockout in November 1974, then defended it against Leonel Hernandez and Rigoberto Riasco. At five feet ten inches, he was exceptionally tall for a featherweight and carried his power without sacrificing balance or accuracy. Kobayashi, a member of Japan’s 1972 Olympic team, had won all 18 of his professional contests and had become known as the “KO Maker.” Trained by Eddie Townsend, he was regarded as one of Japan’s most dangerous young fighters and entered the ring with considerable local support.
The opening rounds were closely fought. Kobayashi attempted to deny Arguello the room required for his straight punches, moving forward and looking to bring his shorter, quicker blows into play. The champion remained upright and composed, judging the distance with his left hand and refusing to be hurried into unnecessary exchanges. Kobayashi’s aggression made him competitive, but it also required him to cross the greater man’s punching range whenever he attacked.
Arguello gradually began to find the target with greater regularity. His work to the body was particularly important. Rather than pursuing an immediate finish, he placed punches beneath Kobayashi’s elbows and then brought his attack back upstairs when the challenger lowered his guard. Kobayashi continued to advance and remained dangerous, but his movements became less brisk as the contest approached its middle stages. The champion’s punches were being delivered with less effort and greater effect.
The decisive change came in the fifth round. Arguello’s body punching broke down Kobayashi’s resistance and left him increasingly exposed to the following blows. The challenger was sent down twice during the round. He rose after the first knockdown, but his strength had been taken from him and Arguello resumed with the same deliberate accuracy. The second knockdown brought the contest to its conclusion at 2 minutes 47 seconds. Kobayashi had shown courage and ambition, but he had been unable to withstand the champion’s accumulated force.
The victory was Arguello’s third successful defence of the WBA featherweight championship and his first defence of the Ring title he had acquired after beating Riasco. It also confirmed his ability to retain his form away from familiar surroundings against an unbeaten challenger fighting before a large home crowd. Kobayashi recovered from the defeat and, almost exactly a year later in the same arena, dropped to junior featherweight and knocked out Riasco to win the WBC championship. For Arguello, the Tokyo victory formed another stage in a championship career that would later carry him to world titles at super featherweight and lightweight.
The House on this fight
I’ve always rated Arguello among the finest technical punchers boxing has produced. He never wasted much. Every shot had a purpose, and against the unbeaten Kobayashi he showed exactly why that matters.
Kobayashi was dangerous, with 16 stoppages from 18 wins, and had 16,000 people behind him in Tokyo. But Arguello stayed composed, used his height and gradually worked downstairs. That body attack took the spring from Kobayashi’s legs and made him increasingly vulnerable.
By the fifth, the challenger was being broken up rather than merely beaten. Two knockdowns finished it at 2:47. Kobayashi later became a world champion, so this was no soft defence. Arguello was simply operating at another level.
