The bombshell that former Foreign Ministry official Bunroku Yoshino dropped last month hasn't had the explosive effect one might expect. Yoshino was in charge of the ministry's American Bureau at the time the United States handed Okinawa back to Japan in 1972, and in an exclusive interview in the Feb. 8 Hokkaido Shimbun he said that Japan paid the U.S. money under the table for the handover.

Ever since suspicions about this secret payment arose at the time, the government has vehemently denied any payment was made, and continues to do so now despite Yoshino's very detailed admission. While the major media reported Yoshino's story, the followup has been virtually nonexistent. One reason for this neglect, though by no means an excuse, is the fact that the news arrived during the Nagata e-mail fiasco in the Diet. One of the ironies of the timing is that the secret payment was the subject of a similar scandal involving a piece of correspondence. In March 1972 an opposition lawmaker presented telegrams in the Diet saying that they were proof of the payment. The government fought back, and Takichi Nishiyama, The Mainichi Shimbun reporter who passed the telegrams to the politician, ended up arrested, fired, and disgraced. Last week, he testified in a suit he has brought against the government for destroying his reputation more than 30 years ago. No news organization covered this testimony.

Given the current controversy over realignment of American forces and Okinawa's status as the host of those forces, the secret payment would seem to be more relevant than ever. The media's lack of interest is difficult to understand.
