The Metropolitan Police Department sent the case to prosecutors the same day.
Naoya Nagatomi, a member of a group affiliated with major yakuza syndicate Sumiyoshi-kai, was arrested Wednesday for repeatedly hitting and kicking Ayato Arai on Monday.
An ambulance was called to an apartment in Ota Ward in the early hours of Wednesday – more than a day after the incident. When it arrived, the boy was covered with bruises and was not breathing.
He was later confirmed dead at a hospital, having suffered a subdural hematoma and hemorrhage in the back of his eyes.
Police will further investigate the case on suspicion that Nagatomi caused injury resulting in death.
Nagatomi, 195 cm tall and weighing 120 kg, admitted to the charges. “I did it because I was angry that (the boy) glared at me. I struck his face many times and threw him to the ground,” police quoted him as saying.
“He jabbed a cooking knife into the floor, and kicked using heel drops. He also said ‘die,’ ” the 22-year-old mother told police.
