Kazuki Anaguchi, 23, had fought seven fights for a record of six victories, including two by knockout, and one defeat. The athlete had been in a coma since his brain operation on December 26.
The intervention aimed to treat injuries suffered during his fight against his compatriot Seiya Tsutsumi. He leaves behind a one-year-old daughter, whom he planned to take on vacation with the money won in the fight that was fatal to him. A tragic event which mourns the boxing world.
