Naoya Inoue delivered one of the most authoritative performances of his career on 25 July 2023, dismantling the unbeaten Stephen Fulton Jr to claim the WBC and WBO super bantamweight world titles at the Ariake Arena in Tokyo. In a contest that had been years in the making, the Japanese icon announced his arrival at 122 pounds in emphatic fashion, forcing a stoppage in the eighth round and ending Fulton’s reign as unified champion.

The bout had originally been slated for May in Yokohama before a hand injury delayed proceedings, only adding to the anticipation surrounding one of the most intriguing match-ups in the lighter divisions. Fulton entered the ring with an unblemished record and a reputation for ring intelligence, while Inoue stepped up in weight without the benefit of an interim contest, a bold decision that spoke volumes about his confidence.

From the opening exchanges, it was clear Inoue was determined to control the tempo. He applied steady pressure, worked behind a sharp lead hand and consistently found angles that limited Fulton’s ability to dictate terms. While the American champion attempted to establish his jab and maintain distance, he was repeatedly disrupted by Inoue’s timing and variety.

As the rounds progressed, the challenger’s influence grew. Inoue mixed head and body attacks with precision, gradually eroding Fulton’s defensive shell. The difference in output became increasingly evident, with Inoue landing cleanly and often, while Fulton struggled to match the volume or accuracy being thrown at him. By the middle of the contest, the momentum had swung decisively towards the Japanese star.

The decisive moment arrived in the eighth. Inoue caught Fulton with a perfectly placed left hand that sent the champion to the canvas for the first knockdown of his career. Although Fulton rose, he was unable to recover fully. Inoue closed in swiftly, unleashing a sustained sequence of unanswered punches that prompted referee Hector Afu to intervene, bringing the contest to an end via technical knockout.

The statistics underlined the one-sided nature of the encounter. By the time of the stoppage, Inoue had outscored Fulton by a wide margin, landing 114 punches to his opponent’s 47, including a significant advantage in power shots. It was a clinical display that left little room for debate.

This victory followed Inoue’s previous outing in December 2021, when he halted Aran Dipaen in eight rounds at the Ryōgoku Kokugikan to retain his bantamweight titles. That win marked his final appearance at 118 pounds, and the transition to super bantamweight has now been completed in spectacular style.

In front of an appreciative Tokyo crowd, Naoya Inoue once again demonstrated his exceptional skill, composure and finishing instinct, while Stephen Fulton Jr showed courage but was ultimately outmatched on the night.
