Amid the growing problem of teenage prostitution in Japan, Fukuoka Prefectural Police are stepping up surveillance on young girls who are offering sex via the internet and trying to prevent such cases by posing as potential clients.
The police also are calling on parents to keep a close eye on their children in the summer, when kids spend more of their free time outside.
Last year, 533 teenage girls aged 18 or younger were found offering their services and taken into police custody nationwide. The number was about 20 percent higher than in the previous year.
