Japan's alert system against North Korea not working properly
A drill conducted Friday across Japan turned up glitches in the J-Alert system, which includes a network of loudspeakers that can relay announcements from Tokyo.
J-Alert is a satellite-based system and provides early warnings to more than 200 Japanese municipalities in the Chugoku and Shikoku regions.
According to Kyodo, any missile Pyongyang would launch targeting the U.S. territory of Guam would fly over Shimane, Hiroshima, Ehime and Kochi prefectures, places where the drills were held on Friday.
J-Alert also transmits to mobile phones and televisions and warns people to take shelter. ■
