Second Japanese boxer dies in days: Shigetoshi Kotari succumbs to brain injury

Japanese boxer Shigetoshi Kotari, 28, tragically passed away after suffering a brain injury during his title fight against Yamato Hata on August 2 in Tokyo.

Kotari underwent emergency brain surgery to treat a subdural hematoma, a life-threatening condition where blood collects between the skull and brain but sadly didn't survive. 

The World Boxing Organization (WBO) paid tribute to him, calling him a "warrior in the ring" and a "fighter in spirit". Kotari had a record of 8 wins, 2 losses, and 2 draws, and his death has sparked an outpouring of condolences from the boxing community.

Tragic news hit the boxing world as Hiromasa Urakawa, 28, succumbed to injuries from his knockout loss to Yoji Saito on August 2.
