Junto Nakatani Stops Ryosuke Nishida to Unify Bantamweight
A Night of Knockouts and Rising Stars at Ariake Coliseum
On June 8, 2025, Tokyo’s Ariake Coliseum played host to Prime Video Boxing 13, a stacked card headlined by Junto Nakatani’s emphatic sixth-round TKO over Ryosuke Nishida. The victory earned Nakatani the IBF and WBC World Bantamweight Titles, solidifying his place among the elite in the 118-pound division.
Main Event: Nakatani vs. Nishida – A Statement of Power
Nakatani, already holding the WBC strap, entered the ring as a heavy favorite—and he delivered. After five rounds of calculated pressure and body work, the ringside physician examined Nishida after Round 6, and Nishida retired on his stool because his right eye was shut. The official result: TKO (Retirement), Round 6, 3:00.
With the win, Nakatani improved to 28-0, continuing his unbeaten streak and setting the stage for a potential mega-fight with Naoya Inoue. Nishida, who showed heart but couldn’t match the pace, fell to 9-1.

What the Result Means
Nakatani entered the contest as the WBC champion, while Nishida brought the IBF belt, making the bout a genuine unification rather than a defense of a single title. Top Rank reported that Nishida retired on his stool after six rounds following an examination by the ringside physician, as his right eye had been shut by Nakatani’s punches. That distinction matters: the result was a stoppage after round six, not a corner throwing in a towel during the round. The win joined two championship lineages at bantamweight and gave Nakatani his first unified title. It also underlined the risks in a high-output fight: a boxer may remain competitive and determined, yet a doctor or referee can stop a bout when an injury compromises safety. The event drew attention beyond the result because it placed two Japanese champions together in a unification match at Ariake Coliseum.
