TRANSLATION - Page 2 "In one of the books written in the United States about the attack on Pearl Harbor, the author deemed it unlikely that such important information would have come to the attention of the Minister of Peru while escaping the notice of secret agents of the American Embassy in Tokyo. What is certain is that without looking for it and without having an intelligence service (information regarding), the initial Japanese preparations for the surprise attack on the American naval base came to the attention of Dr. Rivera Schreiber. "The information received by the Minister about this plan extended over a period of two months. During that period he gradually gathered the data which his domestic servant sponta-' neously supplied him which coincided with the trips to Tokyo of the employee of the Peruvian Consulate in Yokohama. Initial information had it that the Japanese squadron would, in a surprise move, sink the American squadron; according to a second report the operation was to take place in the central Pacific; [and] according to a third report it was to be carried out by aircraft. At first he3/ hesitated to lend credence to such information, which seemed fantastic [and appeared to be] an outgrowth of patriotic Japanese fervor. He was fully convinced only when a Japanese friend, an interpreter of the War Ministry, a Professor of Spanish Literature at the University of Tokyo and a man inclined to oppose militarism, in the excitement of a dialogue, confided to him -- about January 26, 1941 -- that he had proof that at that very time aircraft car- riers of the Japanese squadron were steaming toward southern Japan with a view to beginning tests for the air attack which they were planning [to carry out] against the American squadron at Pearl Harbor and that they would use a small Japanese island for those tests. Such definitive and precise information, which coincided in every respect with the data received from the other source, persuaded him of the probability of the attack on Pearl Harbor. Moreover, months later, as shown in the memoirs of Secretary of State Cordel[l] Hull, the Japanese Government's secret cables to its Embassy in Washington -- decoded by the American services -- confirmed that that very day the simulated attacks referred to by the Japanese informant were carried out. "Without wasting a minute, he personally telephoned Mr. Joseph Grew, United States Ambassador in Tokyo, and they agreed to meet immediately. The conversation took place in Mr. Grew's office at the American Embassy residence. They sat down on a small sofa and chatted for more than an hour during which the Minister of Peru scrupulously related to him the details of the important information. The American Ambassador appeared to be quite moved by and immensely grateful for this friendly gesture and literally said, 'This is a great service you are rendering to my country _________________________ 3/ Tr.: Supra.
