Japan and South Korea are set to agree early next month to link their radars via a U.S. system to share real-time information on North Korea's ballistic missiles, a person with knowledge of the matter said on Tuesday.
With North Korea launching ballistic missiles at an unprecedented pace in the past year, the three countries in November agreed to speed up information-sharing. Japan and South Korea are independently linked to the United States' radar systems but not to each other.
