Interrogations of Japanese Officials
Foreword
The interrogations in this volume were conducted in TOKYO during the months of October, November, and December 1945 by officers of the Naval Analysis Division of the U.S. Strategic Bombing Survey. While the original purpose of the interrogations was to gain evidence for an assessment of the role of airpower in the war with JAPAN, in the absence of any other body concerned with the conduct of this naval war, this purpose was broadened to include as wide a survey of wartime events as time and other restrictions would permit. The specific purpose of individual interrogations varied between that of obtaining comment and opinion from those very senior officers who were in a position to view the war as a whole, the discussion of specific operations and engagements with responsible commanders or other eyewitnesses, and the elaboration and clarification of documentary material.
Although the Imperial Japanese Navy was abolished shortly after the surrender, and its personnel retired and dispersed, permission was obtained from General MacArthur to retain a nucleus of experienced officers at the Naval War College at HIYOSHI. In addition to being interrogated on their particular specialties and experiences, these officers performed research at the direction of the Naval Analysis Division and, together with the Japanese Naval Liaison Officer, gave useful assistance in identifying and procuring other officers for interrogation.
Despite the cooperation of the Japanese, a number of unavoidable difficulties hindered the investigation. It was often a considerable problem to identify the proper individual for interrogation on a given subject, in many instances the most desirable candidates were dead, and in almost every case the selected officers had to be brought especially to TOKYO from all parts of JAPAN and even, in one case, from as far as SINGAPORE. All work was conducted by a small staff under pressure of time, without an adequate library, and in the face of an almost complete lack of original Japanese documents which had been either burned in air raids, or destroyed or hidden on surrender. Towards the end of the stay in JAPAN a quantity of hidden records were discovered; these have been returned to the United States and are now in process of translation, a work which will require a period of years to complete. In many instances, therefore, questions had to be explored entirely by interrogation with only partial or inaccurate war-time information as the starting point, with resultant delay and repetition.
So far as the question of veracity is concerned, it should be stated that almost without exception the Japanese naval officers interrogated were cooperative to the highest degree, and that no important attempt consciously to mislead the interrogator was ever noted. Accuracy on fine points was inevitably affected by the language problem which necessitated in most cases translation of both question and answer, by the specialized nature of the naval vocabulary which in some instances troubled the interpreters, and by the somewhat imprecise nature of the Japanese language itself. Allowance must also be made for the normal fallibility of human memory and in particular the memory of events months or years in the past which were witnessed under the intense strain of combat. Despite all these considerations it is felt that the interrogations provide an accurate picture of the war from the Japanese viewpoint, subject only to the qualifications that on important or disputed points documentary confirmation should where possible be obtained.
The planned use of this material was, as has been noted above, as evidence for an evaluation of the role of airpower in the Pacific war. These interrogations, together with other material accumulated by the Naval Analysis Division, form the basis of reports to be submitted to the chairman of the U.S. Strategic Bombing Survey. In view, however, of the wide range of subject matter covered, the important and in some cases unique qualifications of the Japanese officers interrogated, and the improbability that such an investigation will ever or could ever be repeated, it is believed that these interrogations form a body of source material indispensable to any future study of the war with JAPAN.
