MITO - A 42-year-old mother accused of killing her two children at their apartment in Ibaraki Prefecture in July 2023 was sentenced to eight years in prison by the Mito District Court on November 5th, after judges ruled that her ability to stop herself from committing the crime had been severely impaired by her mental condition, resulting in a sentence 10 years shorter than prosecutors had requested.
Akiko Ota, who appeared in court wearing a black suit, was charged with murdering her eight-year-old son, Keima, and five-year-old daughter, Riko, by stabbing them in the neck with a kitchen knife at their home in July 2023.
During the trial, testimony from colleagues and friends painted a picture of a conscientious and devoted mother whose mental health had deteriorated significantly in the period leading up to the killings.
A former female colleague described Ota as "serious, hardworking and responsible," while a friend recalled her as "a cheerful and kind mother" who appeared to have deep affection for her children.
However, those close to Ota noticed troubling changes in her behavior before the incident. One friend said conversations with her had become increasingly difficult, describing her as looking exhausted and emotionally drained.
According to testimony presented during the proceedings, Ota had developed strong dissatisfaction with changes in the management policies of the restaurant where she worked, contributing to a deterioration in her psychological condition.
Prosecutors cited statements Ota made during the investigation to explain the circumstances behind the killings. They said she had begun suffering from depression, insomnia and growing distrust of others, eventually contemplating suicide.
According to prosecutors, Ota came to believe that her children would be unable to survive without her and that they could be reunited in heaven after death. These thoughts were presented as central to her motivation for killing the children.
However, Ota repeatedly told the court that she could not remember her thoughts or actions at the time of the incident. When questioned about her motive, she responded, "I don't know."
Her defense lawyers argued that the killings were the consequence of a mental illness and maintained that she had been legally insane at the time of the offense. They sought an acquittal on the grounds that she lacked criminal responsibility.
In delivering the verdict on November 5th, the presiding judge rejected the argument that Ota had been entirely incapable of understanding or controlling her actions.
The court found that ordinary psychological motivations, including her desire for the three family members to remain together, had continued to influence her behavior to some extent. It therefore concluded that she had not been in a state of complete mental incapacity.
Nevertheless, the court recognized that Ota's ability to restrain herself from carrying out the killings had been severely diminished, establishing that she was suffering from substantially impaired mental capacity at the time.
On that basis, the court sentenced her to eight years in prison, substantially below the 18-year term sought by prosecutors.
Ota remained motionless and stared straight ahead as the judge delivered the verdict.
