Confirming J - Alert System In Case Of Missile Test

Confirming J-ALERT system in case of missile testJapan's government is asking officials of local administrations, major railways, and telecommunications companies to confirm the integrity of their parts of the national emergency alert system.
The precaution follows the test-launch of a missile by North Korea on February 12th.

The North said it was a new ground-based medium-range ballistic missile, remodeled from a submarine-launched type. The country has hinted it may test-fire an intercontinental ballistic missile soon.

Japan will use its national J-ALERT system to warn the public if North Korea fires a missile that could fall onto Japanese territory or waters. It will also transmit an estimated landing location.

Cities and towns across Japan are to relay the message to the public using loudspeakers of public address systems and area mails.

Officials will be instructed at a briefing session on Thursday and Friday to ensure their parts of the system are working properly. They will also be informed that the alert sound of Japan's public address system has been changed to the one that conveys a sense of urgency.

The government previously held briefings on the J-ALERT system after North Korean announcements of planned rocket tests. This will be the first briefing without any prior notice from the North.

Experts say it's becoming increasingly difficult to detect imminent launches by North Korea. The missile the country fired last week used solid fuel, which requires less preparation time, making it harder to find.
