The missiles are deployed at Amami while shore-base anti-ship missiles are deployed at Setouchi. Both units will be activated on Mar. 26.

On that same day, another Ground Self-Defense Force base will open on Miyako island in Okinawa. It will eventually host surface-to-air and anti-ship missiles as well.
