The number of crimes targeting children has risen alarmingly in Japan and the majority of elementary school children now carry portable crime-prevention alarms. The alarms are designed to alert passers-by in the event of an incident, but the fact that only one in ten adults can recognize the sound of an alarm diminishes their effectiveness as a crime-prevention measure. This radio spot effectively utilizes the characteristics of the media to educate the public about the actual sound of a crime-prevention alarm, aiming to make the streets of Japan a safer place for children.
