TOKYO -- As the U.K. makes overtures toward Japan about working more closely with or even joining the Five Eyes intelligence-sharing alliance, Tokyo faces the task of ensuring it can keep sensitive data safe both within and outside the government.
While Japan shares information with the group's members -- the U.K., the U.S., Canada, Australia and New Zealand -- it is not itself part of Five Eyes. Joining would allow for intelligence to be made available at an earlier stage as well as facilitate sensitive communication.
