- It followed death of Shigetoshi Kotari who fought on same card
The boxing world is in a state of shock and mourning after the death of Japanese boxers Shigetoshi Kotari and Hiromasa Urakawa, who died following brain injuries sustained on the same card.
Urakawa was hospitalised and underwent surgery after suffering a brain injury during an eighth-round defeat by Yoji Saito on August 2.
A craniotomy was performed following Urakawa’s knockout.
However, Ring Magazine have reported that the 28-year-old sadly passed away.
His death comes just a day after his fellow boxer Kotari, who had also featured on the card, succumbed to his injuries in hospital.
Following the event, the Japanese Boxing Commission announced an immediate rule change. All Oriental and Pacific Boxing Federation title bouts will now be 10 rounds instead of 12.

‘Kotari, 28, lost consciousness after the 12-round bout for Yamato Hata’s OPBF super featherweight title. He was rushed to a hospital for emergency brain surgery, suffering a subdural hematoma, which is another term for a brain hemorrhage.
‘Kotari, from Nagoya, had won two consecutive eight-round fights by unanimous decision to earn this title shot.
‘The WBC and its president, Mauricio Sulaimán, deeply mourn this irreparable loss and wish his family and friends strength during this difficult time. Rest in Peace…’
