Japanese Boxer Naoya Inoue Triumphs Over American Stephen Fulton, Clinching Four-Category World Champion Title

Moreover, this triumph marked Inoue's 25th consecutive win, with his last six fights all culminating in an early knockout.

Earlier this year, Inoue relinquished all his lightweight titles and advanced to the heavyweight division. The 29-year-old Fulton held a joint championship of the WBC and WBO in the super lightweight category.

Dominating the ring for seven rounds, Inoue persistently attacked Fulton. The decisive moment came in the eighth round. Fulton initially managed to recover from a series of blows to the head, but Inoue then cornered him, leading the referee to call an end to the fight.
