The boxing world is sad after Shigetoshi Kotari passed away. He was 28 and took his last breath just six days after his fight with Yamato Hata in Tokyo.
The fight on August 2 was hard and went all 12 rounds, and ended in a draw. Later, doctors found he had a serious brain injury from the fight.
Despite having emergency brain surgery, he tragically never recovered. Fans, friends, and other boxers were shocked when news of Shigetoshi Kotari’s death emerged on August 8, 2025.
[UPDATE] A Dark Night for Japanese Boxing
The tragedy of Shigetoshi Kotari’s death became even harder to bear when it was revealed that another boxer, Hiromasa Urakawa, also died from a brain injury in a different fight on the same night. Both men were just 28 years old.
In the history of Japanese boxing, this was one of the most terrifying nights. To increase safety, the Japan Boxing Commission swiftly announced changes. There will now be 10 rounds instead of 12 in OPBF title contests. Weigh-in rules, hydration checks, and fighter medical care are also being examined.
