This March, the Expert Committee on the so-called Secret Agreements between the United States and Japan submitted its report to the Foreign Minister. Some of the secret agreements between the two countries regarding the Japan-U.S. Security Treaty and the reversion of Okinawa to Japan that were said to be “nonexistent” were certified as existing agreements, and the debate over its judgment is continuing. Meanwhile, with the closure of the investigation into the secret agreements, the Ministry of Foreign Affairs has disclosed many of the related classified documents. Based on these newly disclosed documents, Prof. Hatano Sumio, who was a member of the above Committee, will talk about the issue in regard to the Japan-U.S. Security Treaty, which is at the root of the “secret agreement issue,” the reversion of Okinawa and the “secret nuclear pact,” and the difference in understanding between Japan and the United States.
