Police in central Japan's Shizuoka Prefecture have notified a child consultation center over a 13-year-old girl who allegedly stabbed her mother to death with a knife.

They received a call from a family member shortly before midnight on Monday that a woman had been stabbed at her home in Makinohara City.

The woman, in her 40s, was pronounced dead at a hospital.

Sources say she had multiple stab wounds to her neck and elsewhere.

Police questioned her daughter, who was at the home, and she admitted to committing the crime.

Japanese law stipulates that children under 14 cannot be held criminally responsible for their actions.

Police plan to investigate the circumstances that led to the stabbing.
