Two Japanese Boxers, Both 28, Die From Injuries Sustained At The Same Event
On August 2, Shigetoshi Kotari and Hiromasa Urakawa — both 28 years old — suffered fatal brain injuries while competing in separate matches during an event at Tokyo’s Korakuen Hall.
Kotari collapsed shortly after completing a 12-round draw against Oriental and Pacific Boxing Federation junior lightweight champion Yamato Hata.
Despite their efforts to treat his subdural hematoma — a dangerous condition caused by bleeding between the brain and the skull — he passed away on Friday, August 8.
In another tragic turn, Urakawa was knocked out in his fight against Yoji Saito and also required urgent surgery, undergoing a craniotomy in hopes of survival.
In response to the devastating events, the Japanese Boxing Commission has announced that all OPBF title fights will now be reduced from 12 rounds to 10.
The World Boxing Organization (WBO) posted separate tributes for each of the fighters on social media.
“A warrior in the ring. A fighter in spirit. Gone too soon.”
“Our thoughts and prayers are with his family, team, and the entire Japanese boxing community.”
“We extend our deepest condolences to the families, friends, and the Japanese boxing community during this incredibly difficult time.”
Urakawa, a lightweight, had a professional record of 10 wins (7 by knockout) and 4 losses, while featherweight Kotari had fought 12 times, earning 8 wins, 2 losses, and 2 draws with 5 knockouts.

“Finally the time has come. What I’ve been accumulating. Bet it all and go win. I will definitely be a champion.”
“Tomorrow at the venue, U-NEXT live broadcast. Thanks in advance for your support!”
“Stay tuned. Osu.”
Urakawa also shared his anticipation, writing: “Passed the weigh in! Preparing for tomorrow.”
“2025, I’m only going to focus on winning. Thank you for your support this year,” he said in another post.
