The Foreign Ministry kept a written record of a meeting with the U.S. ambassador in 1968 in which he reminded ministry officials of a secret 1960 bilateral nuclear deal, a former senior ministry official said Tuesday, further contradicting government claims that no such pact existed.
Prime Minister Yukio Hatoyama's administration has been pressing the ministry to reveal whether there was a secret U.S.-Japan pact since assuming office last month. Up to now, the Foreign Ministry has repeatedly denied the existence of a deal despite confirmation of the pact in declassified U.S. documents and statements by former Japanese vice ministers.
According to the senior official, who once headed the ministry's former Treaties Bureau and who spoke on condition of anonymity, the records were maintained covertly by the Treaties and the North American Affairs bureaus at least until the end of the 1990s.
