Children subjected to strict discipline, which is sometimes seen as child abuse by the minors themselves, tend to repeat crimes such as extorting money and assaulting others, according to a survey conducted by the Japan Federation of Bar Associations.

In cases where large differences existed in the perception of what constituted discipline by the parents and the children, about 75 percent continued to get in trouble when they got older, according to the results of a survey the federation plans to release at a symposium in Nara on Thursday.

Yoshifusa Saito, a lawyer who serves as the head of the executive committee for the symposium on human rights protection, said, "Even if parents think they love their children, if the children aren't convinced, then (the affection) is simply self-centered on the part of the parents."
