Japan will upgrade its J-Alert early warning system by next summer after it malfunctioned in October when North Korea launched a ballistic missile over the archipelago for the first time in five years, , the Cabinet Secretariat says.
Multiple North Korean missiles headed toward Japan prompted the country to issue emergency alerts for people in at least three northern prefectures on Thursday morning.
Japanese Chief Cabinet Secretary Hirokazu Matsuno apologizes for the malfunctioning of the government s J-Alert early warning system in nine of Tokyo s island towns and villages after a North Korean ballistic missile launch the previous day.
