TOKYO - The Japanese government is considering requiring certain stalking offenders to wear GPS tracking devices under a new system that would alert victims when an offender approaches their home, workplace or another protected location. Chief Cabinet Secretary Kihara said the government was conducting an intensive study into stronger measures against stalking, including the possibility of fitting perpetrators with GPS devices. The government plans to compile emergency measures soon, centered on strengthening protection for victims, following a series of stalking-related incidents. It says alerts should be issued only when an offender enters a designated area around a victim's home, workplace or another specified location. South Korea has already introduced a system requiring repeat stalking offenders to wear GPS tracking devices.
