PDF Summary:Ghosts of Honolulu, by Mark Harmon and Leon Carroll Jr.

Ghosts of Honolulu, by Mark Harmon and Leon Carroll Jr., explores the complex challenges faced by Japanese Americans during World War II, intertwining loyalty, cultural identity, and the crucial role of intelligence operations. The narrative delves into the lives of individuals like Douglas Wada, whose dual heritage caught him between allegiances as he assisted Naval Intelligence in thwarting espionage from within the vibrant Japanese community in Hawaii.

The authors shed light on the Japanese spy ring led by Takeo Yoshikawa, whose meticulous efforts enabled the Pearl Harbor attack. While mainland Japanese Americans endured mass incarceration, Hawaii's approach was shaped by Nisei intelligence operatives who advocated for protecting civil liberties. This insightful account examines the enduring impact on Naval Intelligence and the cultural revival of Japanese Americans following the war's upheaval.

(continued)...

Yoshikawa's efforts to collect information went well beyond simple surveillance. With the indispensable aid of two Japanese American aides from the consulate, he gained access to crucial logistical support, transportation, and vital information networks. He also cultivated relationships with individuals such as Robert Glover, an American kendo instructor who unwittingly divulged details regarding the U.S. Navy, despite his concurrent service in the naval reserves. The authors detail the involvement of Otto Kuehn, a German national with Nazi connections, who established a clandestine communication network employing coded light signals, other signaling techniques, and hidden messages in advertisements, all of which were employed by the Japanese navy before the attack on Pearl Harbor.

Warnings conveyed through messages that could have provided advance notice of the imminent attack were ultimately ignored or misinterpreted, despite their capacity to raise an alarm.

Efforts were simultaneously being made to decode the messages from the consulate while Yoshikawa was active in Honolulu. The narrative delves into the secretive activities of Captain Irving Mayfield's 14th District Intelligence Office, which included the surveillance of communications at the consulate and the interpretation of messages sent via RCA. Station Hypo, a covert group adept in cryptanalysis situated at Pearl Harbor, adeptly intercepted and deciphered communications from Japanese naval units, which encompassed particular intelligence requests stemming from their spies within Honolulu. The Naval Intelligence Office, along with Station Hypo, had decoded a multitude of messages that clearly pointed to an impending attack on Pearl Harbor shortly before it happened.

The book details a succession of oversights, instances of negligence, and misunderstandings that led to senior military officials in Hawaii disregarding or downplaying these warnings. The authors highlight the leadership's disregard, viewing the intercepted messages as either unclear or routine intelligence gathering, which led to an underestimation of the significance of Japanese espionage efforts. The book also elaborates on how critical intelligence regarding an imminent Japanese attack was not conveyed by authorities in Pearl Harbor and Washington D.C. to the military commanders in Hawaii.

Following the bombing at Pearl Harbor, stringent measures were enacted to dismantle Japanese spy networks.

In this segment of the tale, the story delves into the rapid measures undertaken by espionage operatives to dismantle Yoshikawa's spy ring after the attack. The investigative team, fueled by a blend of anger and grief, relentlessly pursued justice by ensuring that all individuals involved in planning and facilitating the attack were held responsible.

Individuals suspected of espionage, including staff from the embassy and their local counterparts, were detained and interrogated.

Following the attack, Harmon and Carroll Jr. depict a hive of activity at the ONI and FBI offices. The team quickly assembled at the Japanese embassy, seizing documents, interrogating staff members, and thoroughly investigating clues linked to the espionage ring. Wada and Iwai were instrumental during the interrogation of Ensign Kazuo Sakamaki, the first prisoner of the war, from whom they obtained vital information, such as the strategic use of small underwater crafts by Japan in the attack. The interrogation was crucial in identifying Yoshikawa as the key operative in the spy ring.

The narrative details the capture and subsequent interrogation of key individuals, among them the consulate's financial specialist Kokichi Seki, along with his colleagues Richard Kotoshirodo and John Mikami, as well as Otto Kuehn, a German national. The authors describe the interrogation methods that resulted in gathering crucial evidence and confessions, which uncovered Yoshikawa's widespread espionage activities and his connections with local conspirators.

The goal was to uncover the espionage activities of the Japanese and to make certain that the individuals accountable were prosecuted.

Utilizing decoded communications, along with confessions from key plotters and materials obtained during the consulate raid, the FBI and ONI were resolute in their mission to capture and bring to justice the individuals behind the assault. The publication thoroughly details the spy operations conducted by Yoshikawa, tracking his movements, pinpointing individuals he collaborated with, and outlining how the information he gathered was sent from Honolulu to Tokyo. The investigation uncovered that the diplomatic mission deliberately created false identities for their intelligence operatives, obtained finances without the necessary authorization, and exploited the deep-seated social and cultural ties among the Japanese American population in Honolulu.

The narrative underscores the challenges faced by intelligence agencies in ensuring accountability for key figures in Japan, even though they were successful in capturing significant personalities. Concerns over potential reprisals aimed at U.S. diplomats within territories under Japanese authority, coupled with the complex legal matters associated with espionage, made it impractical to legally pursue the main individuals involved in the espionage activities, who used the pseudonym "Morimura." The narrative details the controversial decision to repatriate embassy personnel to Japan, thus allowing them to avoid prosecution for their roles in the Pearl Harbor assault.

Other Perspectives

• The Japanese espionage system may not have fully collapsed post-Pearl Harbor, as intelligence operations are often multi-layered and can persist even after key operatives are compromised.
• The effectiveness of Yoshikawa's intelligence in enabling the Pearl Harbor attack could be debated, as the success of the attack was also due to other factors, such as tactical surprise and American unpreparedness.
• The extent of collaboration with local Japanese Americans could be nuanced, as not all Japanese Americans were involved or supportive of espionage activities, and some may have been unfairly targeted or suspected due to their ethnicity.
• Some historians argue that warnings of the attack were not so much ignored or misinterpreted, but rather not recognized for their significance due to a lack of context or the overwhelming amount of intelligence "noise" at the time.
• The post-attack measures to dismantle spy networks might have had unintended consequences, such as the internment of Japanese Americans, which is now viewed as a grave injustice.
• The detention and interrogation of suspected spies could be criticized for potentially violating civil liberties or for being driven by racial prejudice rather than solid evidence.
• The prosecution of those responsible for espionage activities might not have been as straightforward as suggested, with legal and diplomatic complexities that could have hindered the process.

The constraints and restrictions imposed on Japanese Americans, including the valuable input from intelligence operatives who were of second-generation Japanese American heritage.

This segment of the narrative explores the profound societal repercussions that arose following the attack on Pearl Harbor, highlighting the harsh conditions of the war era and the extensive internment of Japanese Americans. Harmon and Carroll Jr. emphasize the stark difference between the indiscriminate internment of Japanese Americans throughout the mainland United States, fueled by widespread apprehension and prejudice, and the more discerning approach taken in Hawaii, where local intelligence recognized the loyalty of the majority of Japanese Americans.

The narrative explores the complex roles of Japanese American intelligence agents from the second generation, highlighting their involvement in the spy network that monitored their own community while advocating for their people's civil rights and freedoms. They explore the intricacies of expressing allegiance through service and scrutinize the transformation of personal identity in individuals of Japanese descent, especially within the Hawaiian context.

The strategy employed in Hawaii offered a more equitable option in contrast to the extensive confinement of Japanese Americans that occurred on the West Coast.

The surge of animosity directed at Japanese people in America, which intensified after the assault, was fueled by a combination of wartime hysteria, entrenched biases, and political figures who exploited the circumstances. They examine the role of influential figures such as California governor Culbert Olson and newspaper columnist Henry McLemore in escalating public fear and advocating for the removal of citizens of Japanese descent. The story details the circumstances leading to President Roosevelt's issuance of Executive Order 9066, which mandated the forced removal of Japanese Americans from areas considered critical to national defense, a decision shaped by the counsel of military authorities and influential politicians from the West Coast.

The authors contrast this with the situation in Hawaii, where local intelligence officials, including FBI SAC Robert Shivers, Army Colonel George Bicknell, and ONI Captain Irving Mayfield, along with Nisei agents like Wada and Iwai, understood the loyalty of the Japanese American community and advocated against mass incarceration. The story highlights the commitment of these individuals to provide accurate assessments of the actual threat posed by the Japanese activity in Hawaii, while promoting a measured approach that focused on examining particular individuals rather than broad internment based solely on ethnic background. The authors attribute the advanced tactics utilized in Hawaii to the acumen of intelligence agents like Kenneth Ringle, who recommended assessing individuals individually and encouraging local community participation rather than depending on biased judgments.

Kenneth Ringle was a staunch advocate against indiscriminate detentions, emphasizing the loyalty of American citizens with Japanese ancestry.

Leon Carroll Jr. presents Ringle's numerical evaluations for the readers to contemplate. He concluded that the issue often referred to as the 'Japanese Problem' has been exaggerated beyond its actual significance, primarily due to the distinctive physical traits of the individuals in question, and the report suggests a radical approach: to embrace them as a permanent segment of the American populace, irrespective of their distinct racial characteristics, and to grant them the rights and privileges that come with being a part of the nation, along with the expectation that they will also shoulder the responsibilities and commitments that accompany such status.

Masaji Marumoto, along with other Nisei figures, worked tirelessly to ease the tensions between the Japanese residents of Hawaii and the armed forces personnel.

The narrative highlights the challenges faced by Nisei community leaders like Masaji Marumoto, who navigated the complex and charged atmosphere in Hawaii when war was ongoing. In their quest to support the war effort and protect the rights and interests of Japanese Americans, these leaders worked in conjunction with military authorities and simultaneously navigated the social unrest and cultural constraints imposed by military rule. The book details Marumoto's development of important relationships with key intelligence individuals, including the principal special agent Shivers and an Army Colonel named Marston. The narrative delves deeper into Marumoto's crucial role in founding the Emergency Service Committee, a group dedicated to nurturing a strong sense of national loyalty among Japanese Americans, aiding war relief efforts, and improving communication between military officials and the community.

The policies of confinement and detention caused considerable turmoil, leading to the collapse of cultural establishments among Japanese Americans and disrupting the committed efforts of Nisei intelligence officers.

This subsection delves into the profound effects of the stringent policies and the excessive intervention by authorities on the Japanese American community. The book delves into the damage inflicted upon cultural identities and the feeling of seclusion experienced by Japanese Americans, as well as the psychological pressure faced by those of the second generation as they strive to reconcile their cultural heritage with their commitment to a country that questioned their fidelity.

The dismantling of schools, various organizations, and sacred Shinto sites in Hawaii.

Harmon and Carroll Jr. detail how, throughout Hawaii, schools teaching Japanese were shut down, and there was a systematic dismantling of Shinto shrines and Buddhist temples, fueled by fears of allegiance to the emperor, potential foreign influence, and the threat of insurrection. The government's actions resulted in the disbanding of many groups, with their leaders imprisoned or banished, and their assets seized, all under the guise of safeguarding the nation's well-being. The influence of these actions reached beyond institutional boundaries, affecting social and cultural gatherings as well as altering the physical environment. The authors depict the erasure of Japanese cultural legacy by recounting specific events, such as the destruction of the teahouse built by Wada's father, the closure of a beloved local shrine near Wada's home on Kama Lane, and the enforced renaming of the Japanese Hospital, where Marumoto served on the board, highlighting the disruption and eradication of the cultural identity tied to Japan.

Wada and Iwai had the difficult assignment of conducting surveillance on their own ethnic group as part of an intelligence network.

The story delves into the complex and disputed roles held by second-generation agents of Japanese American heritage within this framework. Wada and Iwai carried out espionage activities for the Office of Naval Intelligence and the Army, carefully gathering information on Japanese activities, examining secret documents, and interviewing people connected to their spy network. The writers portray these individuals as motivated by a strong allegiance to their nation and a dedication to protecting it, even as they struggled with the tension of aligning themselves with an organization that frequently tested their personal cultural, religious, and community-based identities. The writers emphasize the mental strain and profound inner turmoil experienced by those who conscientiously carried out their responsibilities, as well as their sense of alienation from the societal bonds that unite people.

The narrative segment describes the expansion of U.S. naval intelligence operations after the Second World War, starting with the establishment of the Office of Naval Intelligence and culminating in the inception of the US Naval Investigative Service in 1966, which would later become known as the Naval Criminal Investigative Service (NCIS).

Wada continued his involvement with naval intelligence after the war, contributing to the trials of war crimes and undertaking counterintelligence operations in Japan.

The narrative highlights Douglas Wada's continuous involvement with naval intelligence, chronicling his role in the Tokyo trials post-war and his subsequent relocation to Japan in 1954, where he assumed the position of a clandestine interpreter and intermediary serving the leader of the American Naval Forces stationed in the Far East. They recount his active role in gathering and examining proof for the Tokyo Trial, where he directly witnessed the interrogation of major figures responsible for the assault on Pearl Harbor, such as Captain Minoru Genda. The authors also reveal Wada's further involvement in covert operations aimed at collecting information on possible dangers, including his input to Project Impulse, which assessed the risks associated with the return of Japanese prisoners of war from China and Russia, and his cooperation with the Japanese government in monitoring Communist activities in the Far East.

The Japanese American community's persistent struggle to reconcile with their historical experiences has lasting repercussions from the conflict.

The narrative portrays the measures undertaken by individuals of Japanese descent in America as a demonstration of their enduring resilience and an effort to reclaim their ancestral culture.

The population of Japanese descent in America grappled with changing social circumstances and their place in the community as they endured the aftermath of the conflict and the period of their confinement.

The book explores the dynamic changes and interactions within the Japanese American community after the war. The story delves into the shift from the first-generation Japanese immigrants, who faced a decline in their societal standing prior to the conflict and the disintegration of traditional frameworks, to their American-born offspring, the Nisei, who gradually forged their own beliefs and gained significance in the community. World War II veterans played a crucial role, bringing back new perspectives and experiences that significantly influenced the evolution and growth of Hawaii's Japanese American society.
