COPY OF AIDE-MEMOIRE PREPARED BY THE EMBASSY OF JAPAN TO THE UNITED STATES APRIL 12, 1954 It is reported that on March 31, Mr. Lewis L. Strauss, Chairman of the Atomic Energy Commission, made the following statements, among others, concerning the thermonuclear test which took place at the Bikini Atoll on March 1, 1954. ‘., . . A Japanese fishing trawler, the 'Fortunate Dragon', appears to have been missed by the search but, based on a statement attributed to her skipper, to the effect that he saw the flash of the explosion and heard the concussion six minutes later, it must have been well within the danger area, .. - '., . . The situation with respect to the 23 Japanese fishermen is less certain due to the fact that our people have not yet been permitted by the Japanese authorities to make a proper clinical examination. It is interesting to note, however, that the reports which have recently come through to us indicate that the blood count of these men is comparable to that of our weather station personnel. .. .’ The portion of Mr. Strauss' statement quoted above not being entirely consistent with information officially received here, the Japanese Embassy wishes to place it on record that factS ascertained by the Japanese authorities on these points are as follows: l. Upon investigation, it has been established that the crew of the Fukuryu Maru No. 5 heard the detonation of the explosion seven or eight minutes after the crew saw its flash. It is estimated that the position of the vessel when they saw the flash and the spot where the ash fell upon them were respectively 19 miles and 26 miles outside the danger-zone which the United States Government had previously estab-~ lished and publicized by the official publication ‘Notice to Mariners'. For the details as to the movement of the vessel reference is made to the . . « Aide-Memoire handed in Tokyo to Ambassador Allison by Vice Minister Okumura of Foreign Affairs on March 27, 1954.
