Biography
Naoya Inoue, born Zama, Kanagawa in 1993, became undisputed four-belt bantamweight champion in just his 24th fight (December 2022, KO 11 over Paul Butler) and undisputed four-belt super bantamweight champion within the same calendar year (December 2023, KO 10 over Marlon Tapales). He is one of two fighters in history (Terence Crawford the other) to be four-belt undisputed in two divisions. As of 2026 his career record is 29-0 with 26 KOs (a 90% KO ratio) — the highest of any pound-for-pound top-five fighter.
