The ring at Yokohama Buntai had barely settled when Takeshi Ishii brought it to sudden silence. The Japanese former kickboxer needed only 65 seconds to knock out Puerto Rico’s Wilfredo Méndez and seize the vacant WBA minimumweight world title on Wednesday night.
Ishii showed no patience for a feeling-out round. From the opening bell he pressed forward at a relentless pace, cutting off escape routes and denying the southpaw the jab that had anchored his own world-title reign. Méndez tried a lateral step to find room and walked straight into a hook to the liver.
A body shot that broke the count
The blow landed with a vicious, delayed effect. Ishii followed it instantly with a short right to the chin, and Méndez crumpled heavily to the canvas. Referee Jean Robert Laine of Monaco picked up the count as Méndez knelt and fought to rise, but the pain was too severe.
“I took a bad body shot,” Méndez said flatly afterwards. “That knocked me down with a bad pain. I couldn’t stand up.” The official time read one minute and five seconds, and the black-and-gold belt was Ishii’s.
Fastest world-title KO in Japanese history
The stoppage did more than crown a new champion. It broke a national record held by Ishii’s own senior stablemate, undisputed super-bantamweight Naoya Inoue. Inoue had stopped Juan Carlos Payano in 1:10 at this same Yokohama venue in 2018; Ishii shaved five seconds off that mark, setting the shortest knockout by a Japanese boxer in a world-title bout.
Ishii, now 12-1 with 9 knockouts, travelled an unusual path to this moment. Trained by former three-division champion Akira Yaegashi and guided by the Ohashi gym, he followed the route of Yoshiki Takei — another kickboxer who turned to international-style boxing when size and physique made the summit of his first sport look distant. At 26, he found a discipline built for his compact power.
The win leaves Ishii with one quiet certainty: his first defence is likely before the year ends. For now, the shortest night of his career has placed him at the tallest point of the minimumweight division.
