One out of every 20 high school girls who took part in a recent survey claimed to have been raped, according to the poll findings released Tuesday.

The poll on sexual violence, which was conducted by the government-backed Asian Women's Fund, was carried out at nine high schools in Tokyo, one in Fukuoka Prefecture and two in Miyazaki Prefecture between Nov. 6 and Dec. 18. The group collected responses from 2,346 pupils -- 1,463 girls and 883 boys.

According to the poll, 5.3 percent of the girls said they had been forced to have sex -- mainly with their boyfriends or other people they knew.
