The documents, published Monday in collaboration with Japanese news
broadcaster NHK, reveal the complicated relationship the NSA has
maintained with Japan over a period of more than six decades. Japan has
allowed NSA to maintain at least three bases on its territory and
contributed more than half a billion dollars to help finance the NSA’s
facilities and operations. In return, NSA has kitted out Japanese spies
with powerful surveillance tools and shared intelligence with them.
However, there is a duplicitous dimension to the partnership. While the
NSA has maintained friendly ties with its Japanese counterparts and
benefited from their financial generosity, at the same time it has
secretly spied on Japanese officials and institutions.
