Japanese Defense Ministry officials told Kyodo news that the Patriot Advanced Capability-3 (PAC-3) system would likely be deployed at Ground Self-Defense Force bases in the western prefectures of Shimane, Hiroshima and Kochi, areas which North Korea said its missiles could fly over.
Japan's missile defense program includes the Maritime Self-Defense Force's (SDF) Aegis destroyers, aimed at shooting down airborne missiles, and the Air Self-Defense Force's PAC-3 system, which is aimed at countering missiles that evade Aegis interceptors. Tensions between Pyongyang and Washington have escalated as the war of words continue between the two countries, with President Donald Trump warning to Kim Jong-un that he "will truly regret" if he issues any hostile action or threat against Guam or any ally of Washington.
North Korea said this week it was examining a plan of a ballistic missile strike near Guam, which hosts several U.S. military bases.
The government wants to be prepared in the event that the North Korean missiles fail as they cross over Japan. As per the television footages, Japan's military vehicles carried launchers and other equipment.
On Friday, President Donald Trump urged North Korean leader Kim Jong-Un not to take any action against the United States, its territories including Guam or its allies, warning he would regret such a move - and "regret it fast".
In 2009, a North Korean rocket passed over Japanese territory without incident, triggering Japan's immediate denouncement.
But the Chinese foreign ministry said Xi urged Trump to avoid "words and deeds" that would "exacerbate" the already-tense situation, exercise restraint and seek a political settlement.
