Japanese Boxers Tragically Die from Brain Injuries After August 2 Fights

Tokyo, Japan – The boxing world is in mourning following the tragic deaths of two Japanese boxers, Shigetoshi Kotari and Hiromasa Urakawa, both aged 28, who succumbed to brain injuries sustained during separate bouts on August 2, 2025, at Tokyo’s iconic Korakuen Hall. The back-to-back fatalities have sparked renewed debate about safety protocols in the sport and prompted immediate action from the Japanese Boxing Commission (JBC).

The Tragic Events

Shigetoshi Kotari, a super featherweight with a professional record of 8 wins, 2 losses, and 2 draws (8-2-2, 5 KOs), competed in a grueling 12-round bout against Oriental and Pacific Boxing Federation (OPBF) junior lightweight champion Yamato Hata. The fight ended in a draw, but Kotari collapsed shortly after, having lost consciousness due to a subdural hematoma—a life-threatening condition where blood collects between the brain and skull. He was rushed to a local hospital for emergency brain surgery but tragically passed away on August 8, 2025, at 10:59 PM, as confirmed by his M.T Boxing Gym. “He did his best to fight his way through the surgery and treatment,” the gym stated, highlighting Kotari’s resilience both in and out of the ring.

Hiromasa Urakawa, a lightweight with a record of 10 wins and 4 losses (10-4, 7 KOs), faced Yoji Saito in an eight-round bout on the same card. Urakawa suffered a technical knockout loss in the final round, marking his first career defeat by stoppage. He collapsed shortly after the fight and was taken to the hospital, where he underwent a craniotomy to treat an acute subdural hematoma. Despite medical efforts, Urakawa passed away on August 9, 2025, just one day after Kotari’s death. The World Boxing Organization (WBO) announced his passing, noting the heartbreaking coincidence of losing two fighters from the same event.

Boxing Community Mourns

The boxing community has been deeply shaken by the loss of these two young athletes. The WBO paid tribute to Kotari, stating, “Rest in peace, Shigetoshi Kotari. A warrior in the ring. A fighter in spirit. Gone too soon.” The organization also extended condolences to Urakawa’s family, friends, and the Japanese boxing community, emphasizing the profound impact of the dual tragedies. The World Boxing Council (WBC) echoed these sentiments, with president Mauricio Sulaimán expressing deep sorrow and calling for continued research to enhance boxing safety.

Kotari’s gym released a heartfelt statement, describing him as a dedicated fighter who gave everything in the ring and during his medical treatment. Urakawa’s death, coming so soon after Kotari’s, has left the sport in a state of shock, with tributes pouring in from fans, fellow boxers, and officials worldwide.

Safety Reforms Prompted

The unprecedented nature of two boxers undergoing skull-opening surgeries from the same event prompted swift action from the JBC. Tsuyoshi Yasukochi, the commission’s secretary-general, noted that this was likely the first time such an incident had occurred in Japan. In response, the JBC announced that all OPBF title bouts will be reduced from 12 rounds to 10, effective immediately, to minimize the risk of severe injuries. This decision follows a historical precedent set after the 1982 death of boxer Kim Duk-koo, which led to world championship fights being shortened from 15 rounds to 12.

The tragedies have reignited calls for broader safety reforms in boxing, both in Japan and globally. Advocates are pushing for mandatory post-fight medical scans, stricter concussion protocols, and enhanced ringside medical oversight to prevent such outcomes. The deaths of Kotari and Urakawa mark the third and fourth boxing fatalities worldwide in 2025, following the earlier loss of Irish boxer John Cooney, who died from a brain injury sustained in a February bout.

A Call for Reflection

The boxing community and fans worldwide are grappling with the loss of two promising athletes who exemplified courage and dedication. Kotari, from Nagoya, was challenging for his first regional title, stepping up from eight-round to 12-round fights, while Urakawa, from Tokyo, was a seasoned fighter looking to rebound from recent setbacks. Neither showed signs of physical distress prior to their bouts, making their deaths all the more shocking.

As the sport reflects on these losses, the focus is shifting toward ensuring that such tragedies are not repeated. The JBC’s decision to shorten title bouts is a step forward, but many believe more comprehensive measures are needed to protect boxers. “Deeply sorry for this loss, a ring accident which makes all of us go back to continue research to find ways to make boxing safer,” said WBC president Mauricio Sulaimán.

The deaths of Shigetoshi Kotari and Hiromasa Urakawa serve as a somber reminder of the risks inherent in boxing and the urgent need for ongoing safety improvements. Their legacies as warriors in the ring will endure, as will the resolve to make the sport safer for future generations.
