Emergency Warning Broadcast System (Japan)

Not to be confused with Emergency Alert System, Emergency Broadcast System, J-Alert, or Emergency Warning System.

Emergency Warning Broadcast System, omitted as EWBS or EWS (緊急警報放送, Kinkyū keihō hōsō) is a warning broadcast system in Japan that is performed by automatically turning on the switch of a television/radio receiver in a standby state by using a specific signal.[1][2]

This is done when a large-scale disaster such as an earthquake occurs or when a tsunami warning is announced, and it is intended to help prevent or mitigate the damage caused by the disaster.
