Sigh. It is about information sharing. Most nations know things about the cyber theft and cyber espionage operations of their adversaries and keep this information very closely held. The US and Japan have some common adversaries so it makes sense for each nation to share what they know about the common threat. It may be that Japan has some uniquely placed people who can fill in holes in the information the US has and vice versa, or that each has unique capabilities the other does not that now can be shared. Don't expect either nation to be too specific on the matter because neither wants to reveal information that would allow their common adversaries to know their cyber operations have been compromised and strengthen their own security.
