Japanese Intelligence In World War Ii

In the eyes of history, Japanese intelligence in World War II has fared very poorly. However, these historians have most often concentrated on the later years of the war, when Japan was fighting a multi-front war against numerous opponents. In this groundbreaking new study, Japanese scholar Ken Kotani re-examines the Japanese Intelligence department, beginning with the early phase of the war. He points out that without the intelligence gathered by the Japanese Army and Navy they would have been unable to achieve their long string of victories against the forces of Russia, China, and Great Britain. Notable in these early campaigns were the successful strikes against both Singapore and Pearl Harbor. Yet as these victories expanded the sphere of Japanese control, they also made it harder for the intelligence services to gather accurate information about their growing list of adversaries. At the battle of Midway in 1942, Japanese intelligence suffered its worst mishap when the Americans broke their code and tricked the Japanese into revealing the target of their attack. It was a mistake from which they would never recover. As the military might of Japan was forced to retreat and her forces deteriorated, so too did her intelligence services.

"This book tells the story of an unusual group of American soldiers in World War II, second-generation Japanese Americans (Nisei) who served as interpreters and translators in the Military Intelligence Service."--Preface.

The prewar history of the Japanese intelligence community demonstrates how having power over much, but insight into little can have devastating consequences. Its postwar history—one of limited Japanese power despite growing insight—has also been problematic for national security. In Special Duty Richard J. Samuels dissects the fascinating history of the intelligence community in Japan. Looking at the impact of shifts in the strategic environment, technological change, and past failures, he probes the reasons why Japan has endured such a roller-coaster ride when it comes to intelligence gathering and analysis, and concludes that the ups and downs of the past century—combined with growing uncertainties in the regional security environment—have convinced Japanese leaders of the critical importance of striking balance between power and insight. Using examples of excessive hubris and debilitating bureaucratic competition before the Asia-Pacific War, the unavoidable dependence on US assets and popular sensitivity to security issues after World War II, and the tardy adoption of image-processing and cyber technologies, Samuels' bold book highlights the century-long history of Japan's struggles to develop a fully functioning and effective intelligence capability, and makes clear that Japanese leaders have begun to reinvent their nation's intelligence community.

The most authoritative and revealing examination yet of the way intelligence--of all kinds--was instrumental in defeating Japan. Prados gives a new picture of the war in the Pacific, one which will challenge many previous conceptions about that conflict, and one which will be irresistible to those readers who find histories of that period fascinating. 16 pages of photos.

In the foreword to this book, first published in 1978, Sen. Daniel Inouye describes the story as ""the raw material of adventure fiction--but this is all true and told in a manner that is at the same time fascinating and professional."" Despite the passage of twenty years and the appearance of several studies of code breaking, this inside look at naval intelligence in the Pacific is as powerful as ever. This book provides a compassionate and unique understanding of the war and the business of intelligence gathering. Assigned to the combat intelligence unit in Honolulu from June 1941 to the end of the war, W. J. Holmes shares his history-making experiences as part of an organization that collected, analyzed, and disseminated naval intelligence throughout World War II. His book not only captures the mood of the period but gives rare insight into the problems and personalities involved, allowing the reader to fully appreciate the painful moral dilemma faced daily by commanders in the Pacific once the Japanese naval codes were broken. Every time the Americans made use of the enemy messages they had decoded, they increased the probability of the Japanese realizing what had happened and changing their codes. And such a change would cause the U.S. Pacific Fleet to lose a vital edge. On the other hand, withholding the information could--and sometimes did--result in the loss of U.S. lives and ships. This revealing study illuminates the difficulties in both collecting intelligence and deciding when to use it.

Nisei Linguists, first published in 2006, is a fascinating, well-documented look at the World War II service performed by second-generation Japanese-Americans in World War II. The men, serving as interpreters and translators for the U.S. Army Military Intelligence Service, made valuable contributions to the war effort including interrogation of prisoners, translating captured documents, making propaganda broadcasts, and assisting in the Allied occupation of Japan. Nisei Linguists provides a detailed description of the training, the camps, and the field deployments of these servicemen. Illustrated throughout with maps and nearly 80 photographs.

While previous writers have focused primarily on strategic, military, and intelligence factors, Walter Grunden underscores the dramatic scientific and technological disparities that left Japan vunerable and ultimately led to its defeat in World War II.

In the history of the twentieth century, the role of the military intelligence services in the competition among nations is still murky. Among the world's foremost intelligence services, those of Imperial Japan remain the least known. Few stories are as compelling as those surrounding the Japanese Army's Nakano School. From 1938 to 1945, the Nakano School trained more than 2,000 men in intelligence gathering, propaganda, and irregular warfare. Working in the shadows, these dedicated warriors executed a range of missions, from gathering intelligence in Latin America to leading commando raids against American lines in Papua New Guinea, in the Philippines, and on Okinawa. They played major roles in operations to subvert British rule in India, and they organized Japanese civilians into guerrilla units that would have made the invasion of Japan a bloodbath. One graduate used his Nakano commando training to elude U.S. and Philippine military patrols until emerging from the jungle nearly thirty years after the war's end. In the decades after World War II, graduates of the school worked to obtain from the United States and Russia the release of imprisoned war criminals and the recovery of lost territory, including Okinawa. Based on archival research and the memoirs of Japanese veterans, The Shadow Warriors of Nakano shines a much-needed light into the shadows of World War II and postwar Japanese affairs.

The Alamo Scouts, Sixth Army's Special Reconnaissance Unit of World War II, provided intelligence-gathering and tactical reconnaissance in the Pacific Theatre. During the war, they performed over 106 successful missions in the Admiralty Islands, New Guinea and the Philippines, most deep behind enemy lines. The Scouts took part in liberating two POW camps. The Scouts evolved from a simple reconnaissance unit to a sophisticated intelligence unit supplying and coordinating large-scale guerilla operations on Leyte and Luzon. They did this without losing a man, killed or captured. The Scouts are now recognised as forerunners of the modern Special Forces.
