The plan emerged as Tokyo aims to acquire "counterstrike capabilities" of attacking targets in enemy territory directly in an emergency, with Beijing's military buildup and provocative activities in waters near Japan, especially the East China Sea, in mind.

[...] The GSDF has deployed surface-to-ship missile units in Miyako and Ishigaki islands in the southern prefecture of Okinawa, Uruma on Okinawa's main island, and Amami-Oshima Island in the southwestern prefecture of Kagoshima. Minamitori Island has no civilian population; only Japanese Maritime Self-Defense Force members and Meteorological Agency personnel are stationed there.
