"Japanese teenage women have grown increasingly violent in the last 20 years,"a criminologist said yesterday. The ratio of women in their teens inflicting bodily injury has risen to more than 20 per 100,000 of the total Japanese population. "More than 7 times the level 20 years ago," said JinSuke Kageyama, a professor at the Tokyo Institute of Technology.
"Japanese males have shifted increasingly to aggression, previously linked with women, such as bullying others by excluding from conversation," he said.
