The boy died from loss of blood in hospital on Sunday
A Japanese father stabbed his 12-year-old son to death with a kitchen knife after the boy failed to study for a school entrance exam, officials said.
Kengo Satake, the boy’s 48-year-old father, told police that he “argued with his son for not studying” before a test to enter a private junior high school, according to public broadcaster NHK.
