Japanese boxing superstar Naoya Inoue retained his undisputed super bantamweight world title with a 3-0 unanimous decision over countryman Junto Nakatani in Tokyo on May 2.
Inoue, 33, extended his record winning streak in world title matches to 28. The fighter known as "The Monster" holds a career record of 33 wins, including 27 knockouts.
Defeat for Nakatani, who was aiming to become a four-division champion, was the first of the 28-year-old's career. He dropped to 32-1 (24 knockouts).
The 33-year-old Inoue failed to register a knockdown, but was in control from the start, pressuring Nakatani with constant feints as he patiently looked for openings. From the middle rounds onward, he became increasingly aggressive, unleashing a barrage of punches in the 11th round. Although Inoue never landed a decisive shot, he showcased impressive speed, movement, and defensive skill.
Nakatani, armed with his powerful left, was able to match Inoue at several points in the bout, but a head clash late in the 10th round slowed the momentum the challenger had built up to that stage.

"I was totally focused on winning and fought with complete belief that I would be the one to come out on top tonight."

Inoue dominated a high-level tactical battle worthy of a title showdown, earning a convincing decision victory over Nakatani, who had expected to "dethrone the champion." Inoue showed no mercy, relentlessly targeting the cut above Nakatani's left eyebrow—opened by an accidental clash of heads -- as he fought with unwavering determination to retain his crown as the undisputed champion. Reflecting on the bout, he said, "I was totally focused on winning and fought with complete belief that I would be the one to come out on top tonight."
Inoue seemed to relish the intensity of a fight in which a single mistake could prove fatal. He had already anticipated Nakatani's left counter after throwing his right hand, narrowly slipping the punch with razor-sharp precision. Nakatani responded with a wry smile, as if acknowledging his opponent's brilliance. Although the fight did not end in dramatic fashion, the crowd remained captivated throughout by the elite-level exchanges of skill and technique.
After moving up to the super bantamweight division in July 2023, Inoue had remained virtually untouchable. Yet in October 2024, he openly recognized Nakatani as a legitimate rival. "There's a young fighter aiming to become pound-for-pound number one," he said at the time. "All I can do is wait for that fighter to rise." It was only natural that his attention turned toward the rising star pursuing the very P4P throne Inoue himself once claimed.
Throughout his career, Inoue has consistently sought out the toughest possible opponents. Nakatani answered that challenge by building an impressive resume of his own, including two world bantamweight titles, as he pursued the summit of the sport. In the long-awaited showdown fans had dreamed of, however, victory belonged to the Monster, whose dominance showed no signs of fading.

"I wasn't surprised. He showed why he is the champion. His technique was amazing."

No new legend emerged from this fight of the century. Nakatani fell agonizingly short against a once-in-a-generation champion, suffering the first loss of his professional career at the fateful Tokyo Dome. His promise -- "I will defeat Naoya Inoue and become champion" -- went unfulfilled.
Nakatani's trainer had forbidden him from sparring with Inoue, telling him, "One day, you'll fight him for real." As that long-awaited moment approached, the strategy was clear: seize the initiative and fight with sharp focus.
The sweeping left hook he unleashed just before the end of the opening round was a statement of intent. Making full use of his three-centimeter reach advantage, he controlled distance with his jab while searching for an opportunity to end the fight with his devastating left hand, known as the "Big Bang." Rather than throwing punches in volume, Nakatani appeared fully committed to landing the one shot capable of defeating Inoue.
But Inoue avoided his tense, explosive punches by the narrowest of margins. Nakatani mounted a fierce offensive with heavy combinations in the 10th round, but failed to produce a decisive breakthrough and was countered in the following round. When the final bell rang, he accepted the decision calmly and bowed respectfully to the massive crowd.

After graduating from junior high school, Nakatani moved alone to the United States in pursuit of becoming the world's strongest boxer. "I want my story to matter," he once said. In the end, whether it was grit or technique that proved just insufficient, the ring showed no mercy. Even so, the defeated challenger earned warm applause from the crowd for his courage and determination.
