The suspect in a stabbing incident at a Tokyo subway station has begun revealing motives to investigators, citing parental pressure to excel in education. He says he aimed to show that parents who are overzealous about their children's schooling can push them to commit crimes.



The suspect also told investigators that he committed the crime because his life fell apart financially.



Tokyo police arrested 43-year-old Toda Yoshitaka on suspicion of assaulting a university student with a knife on the platform at Todaimae Station on the Tokyo Metro Namboku Line on Wednesday evening. The student was injured. Another man was also hurt while detaining Toda.



On Friday, Toda was turned over to public prosecutors on suspicion of attempted murder and violating a law on the possession of firearms and swords.



Investigative sources say the suspect has now admitted to allegations and begun speaking about his motives.



He said that when he was in junior high he became unable to attend school and suffered hardships due to pressure from his education-obsessed parents.



Toda said he wanted to show people that children can turn delinquent and commit crimes if their parents push them too far.



He said financial hardship was another reason for what he did.



Residents around his home said the suspect moved from Tokyo to Nagano Prefecture, central Japan, four years ago and has been living alone.



Toda was believed to have come to Tokyo by train on Wednesday, the day of the incident.
