TY - BOOK AU - SAITO Naoki TI - Japanese Navy's Tactical Intelligence Collection on the Eve of the Pacific War? PY - 2020/// KW - Japan N2 - This article looks at IJN records that have survived in Japanese government archives to provide a more complete picture of IJN intelligence in late 1941 than appears in the existing literature. The article discusses the structure of IJN intelligence and its institutional context, thereby explaining better than the existing literature how IJN intelligence as a whole worked to support the attack. This article first describes the intelligence organization of the IJN on the eve of the Pearl Harbor attack. It then examines how the IJN used most intelligence collection disciplines, including human intelligence (HUMINT), communications intelligence (COMINT), aerial reconnaissance, and counterintelligence to help develop its attack plan, and then to enable the Combined Fleet to return to Japanese waters safe from pursuing American submarines UR - https://www.tandfonline.com/doi/full/10.1080/08850607.2020.1743948 ER -
