Japan expected to take PAC-3 missiles off alert in Tokyo as North Korea fears subside
Media reports said the units were to be taken off alert status as early as Friday, but officials refused to comment.
Japan, South Korea and U.S. troops have been taking special measures to counter North Korean threats that it might launch a long-range missile or some kind of a retaliatory strike if provoked. The tensions reached their peak in April, as the United States and South Korea held large-scale joint military manoeuvrs, but have since calmed down.
Japan deployed PAC-3 anti-missile defence units at three locations in and around Tokyo, which is within range of North Korea's ballistic missiles, in early April.
