Japan plans to deploy surface-to-air missiles at four sites to shoot down North Korean missiles that stray into Japanese territory from their intended target of waters around Guam.

An official decision to deploy the Patriot Advanced Capability 3 (PAC-3) missiles at Ground Self-Defense Force bases in the Chugoku and Shikoku regions will likely be made within a few days, government sources said.

In the escalating verbal war with the United States, North Korea has warned that it plans to fire four missiles over Japan to Guam, home to a U.S. military base.

According to the sources, the PAC-3 missiles will be placed in: Kaitaichi base, Hiroshima Prefecture; Izumo base, Shimane Prefecture; Kochi base, Kochi Prefecture; and Matsuyama base, Ehime Prefecture.

The Maritime Self-Defense Force has sent an Aegis destroyer installed with the SM-3 interceptor in the Sea of Japan to be on guard against North Korea missiles.
