If it is confirmed a ballistic missile has been launched over Japan the government will use the national system of instant warning called “J-Alert” to transmit emergency information.

By using the system “J-Alert” a special alarm along with a message through the emergency transmission system will be issued and an emergency message will be also send to cell phones.

Why sometimes the “J-Alert” system does not activate even if a ballistic missile is launched?

The “J-Alert” is used if there is the possibility of a ballistic missile falls over Japan’s territory or sea or if there is the possibility a missile flies over the country.

Therefore, if it is decided there is no possibility the missile falls over Japan’ territory, sea or flies over the country, the J-Alert will not be issued.

Example of message issued by “J-Alert” system

“TADACHINI HINAN. TADACHINI HINAN. TADACHINI GANJŌNA TATEMONO YA CHIKA NI HINAN SHITE KUDASAI.

MISAIRU GA RAKKA SURU KANŌSEI GA ARIMASU. TADACHI NI HINAN SHITE KUDASAI.”

(Take shelter immediately! Take shelter immediately! Take shelter immediately in resistant structure buildings or underground. We may be hit by a missile. Take shelter immediately!)
