The Japanese National Police Agency has decided to ask for an amendment of the law to obligate operators of dating service Web sites to record with prefectural public safety commissions and to offer for penalties for those that fail to do so. The National Police Agency wants to straightforwardly oblige stricter policy and beef up its monitoring of Internet dating service operators, because the law governing such services, which banns minors under 18 from using them, has been mostly disregarded. The operators of dating service Web sites also would be obliged to erase messages associated with underage girls posted on their Web site. The law regulating Internet dating service sites, which was enacted in September 2003, prohibits minors fewer than 18 from such actions as posting messages on the sites that can be interpreted as soliciting to have paid sex. The revised law also will without a doubt stipulate that service operators must delete problematic messages. The National Police Agency is asking that the revised law allow for a prison term of up to six months for site operators who fail to comply. If operators fail to properly confirm users' ages or to delete problematic messages, the NPA wants the law to allow it to issue correction orders or orders to suspend business. According to the NPA, there are about 5,000 dating service sites on the Internet. The number of juvenile people under 18 who were victims of sex crimes in connection with dating service sites in 2006 increased 92 from the previous year to 1,153. Of the victims, 95 percent accessed the sites via cell phone.
