Japan has put its military on alert as North Korea is showing signs of launching a ballistic missile, Japanese media reports showed Monday.
  
Citing a local government source, NHK reported that the Japanese government has ordered its military to be ready to intercept any ballistic missile to be fired by the North if it enters its territory.
  
Under the order, Japan's military will deploy Aegis destroyers equipped with high-performing radars and intercept capabilities along with ground-based interception missile troops in a bid to step up surveillance.
 
Kyodo News also reported that signs have been detected that the North is preparing a missile launch which it speculated might be a Musudan intermediate-range missile.
  
The Joint Chiefs of Staff here said that it is closely tracking development in the North and ready to react to any provocations. (Yonhap)
