On February 19, 1942, President Franklin Delano Roosevelt issued Executive Order 9066, which sanctioned the removal of Japanese immigrants and Americans of Japanese heritage from their homes to be imprisoned in internment camps throughout the country.
At the time, the move was sold to the public as a strategic military necessity. Following the attack on Pearl Harbor on December 7, 1941, the government argued that it was impossible to know where the loyalties of Japanese-Americans rested.
Between 110,000 and 120,000 people of Japanese ancestry were relocated to internment camps along the West Coast and as far east as Louisiana. Here are 12 facts about what former first lady Laura Bush has described as "one of the most shameful episodes in U.S. history."
1. The government was already discussing detaining people before the Pearl Harbor attack.
In 1936, President Franklin Roosevelt—who was concerned about Japan’s growing military might—instructed William H. Standley, his chief of naval operations, to clandestinely monitor "every Japanese citizen or non-citizen on the island of Oahu who meets these Japanese ships [arriving in Hawaii] or has any connection with their officers or men" and to secretly place their names "on a special list of those who would be the first to be placed in a concentration camp in the event of trouble."
This sentiment helped lead to the creation of the Custodial Detention List, which would later guide the U.S. in detaining 31,899 Japanese, German, and Italian nationals, separate from the 110,000-plus later interred, without charging them with a crime or offering them any access to legal counsel.
2. Initial studies of the “Japanese problem” proved that there wasn’t one.
In early 1941, Curtis Munson, a special representative of the State Department, was tasked with interviewing West Coast-based Japanese-Americans to gauge their loyalty levels in coordination with the FBI and the Office of Naval Intelligence. Munson reported that there was extraordinary patriotism among Japanese immigrants, saying that "90 percent like our way best," and that they were "extremely good citizen[s]" who were "straining every nerve to show their loyalty." Lieutenant Commander K.D. Ringle’s follow-up report showed the same findings and argued against internment because only a small percentage of the community posed a threat, and most of those individuals were already in custody.
3. The general in charge of Western defense command took nothing happening after Pearl Harbor as proof that something would happen.
Despite both Munson and Ringle debunking the concept of internment as a strategic necessity, the plan moved ahead—spurred largely by Western Defense Command head General John L. DeWitt. One month after Pearl Harbor, DeWitt created the central ground for mass incarceration by declaring: "The fact that nothing has happened so far is more or less ... ominous in that I feel that in view of the fact that we have had no sporadic attempts at sabotage that there is a control being exercised and when we have it, it will be on a mass basis."
DeWitt, whose ancestors were Dutch, didn’t want anyone of Japanese descent on the West Coast, stating that “American citizenship does not necessarily determine loyalty.”
4. Almost no one protested internment.
Alongside General DeWitt, Wartime Civil Control Administration director Colonel Karl Bendetsen avowed that anyone with even “one drop of Japanese blood” should be incarcerated, and the country generally went along with that assessment. Some newspapers ran op-eds opposing the policy, and the American Baptist Home Mission Societies created pamphlets to push back, but as historian Eric Foner wrote in The Story of American Freedom, "One searches the wartime record in vain for public protests among non-Japanese." Senator Robert Taft was the only congressperson to condemn the policy.
5. Supporting or opposing internment were both matters of economics.
White farmers and landowners on the West Coast had great economic incentives to get rid of Japanese farmers who had come to the area only decades before and found success with new irrigation methods. They fomented deep hatred for their Japanese neighbors and publicly advocated for internment, which is one reason so many of the more than 110,000 Japanese individuals sent to camps came from the West Coast. In Hawaii, it was a different story. White business owners opposed internment, but not for noble reasons: They feared losing their workforce. Thus, only between 1200 and 1800 Japanese-Americans from Hawaii were sent to internment camps.
6. People were tagged for identification.
Moving entire communities of people to camps in California, Colorado, Texas, and beyond was a gargantuan logistical task. The military assigned tags with ID numbers to families, including the children, to ensure they would be transferred to the correct camp. In 2012, artist Wendy Maruyama recreated thousands of these tags for an art exhibition she titled "The Tag Project."
"The process of replicating these tags using government databases, writing thousands of names, numbers, and camp locations became a meditative process," Maruyama told Voices of San Diego. “And for the hundreds of volunteers, they could, for a minute or two as they wrote the names, contemplate and wonder what this person was thinking as he or she was being moved from the comforts of home to the spare and bare prisons placed in the foreboding deserts and wastelands of America. And could it happen again?”
7. Not everyone went quietly.
Directly combatting the image of the “polite” Japanese-Americans who acquiesced to internment without protest, collections of resistance stories paint a disruptive picture of those who refused to go to the camps or made trouble once inside. Among those who were considered "problematic" were individuals who refused to register for the compulsory loyalty questionnaire, which asked questions about whether the person was a registered voter and with which party, as well as marital status and "citizenship of wife" and "race of wife."
“A broadly understood notion of resistance represents a more complete picture of what happened during World War II,” David Yoo, a professor of Asian American Studies and History and vice provost at UCLA's Institute of American Cultures, told NBC News about collecting these resistance stories. “Because these stories touch upon human rights, they are important for all peoples.”
8. The government converted unused buildings into camp facilities.
For the most part, camps were set against desert scrub land or infertile Ozark hills bordered with barbed wire. Before getting on buses to be transported to their new "homes," detainees had to go through processing centers housed in converted racetracks and fairgrounds, where they might stay for several months. The largest and most noteworthy center was Santa Anita Park, a racetrack in Arcadia, California, which was shut down so that makeshift barracks could be assembled and horse stables could be used for sleeping quarters.
9. Ansel Adams took hundreds of photographs inside the most famous camp, as did an internee with a smuggled camera.
Approximately 200 miles north of Santa Anita Park, at the foot of the Sierra Nevada mountain range, was Manzanar—which, with its 11,000 internees, was perhaps the most famous of America's 10 relocation centers. It was also the most photographed facility. In the fall of 1942, famed photographer Ansel Adams—who was personally outraged by the situation when a family friend was taken from his home and moved halfway across the country—shot more than 200 images of the camp. In a letter to a friend about a book being made of the photos, Adams wrote that, "Through the pictures the reader will be introduced to perhaps 20 individuals ... loyal American citizens who are anxious to get back into the stream of life and contribute to our victory."
While Adams may have successfully offered a small glimpse at life inside Manzanar, Tōyō Miyatake—a photographer and detainee who managed to smuggle a lens and film into the camp, which he later fashioned into a makeshift camera—produced a series of photos that offered a much more intimate depiction of what everyday life was like for the individuals who were imprisoned there between 1942 and 1945. Today, Manzanar is a National Historic Site.
10. Detainees were told they were in camps for their own protection.
Just as the justification for internment was an erroneous belief in mass disloyalty among a single racial group, the argument given to those incarcerated was that they were better off inside the barbed wire compounds than back in their own homes, where racist neighbors could assault them. When presented with that logic, one detainee rebutted, “If we were put there for our protection, why were the guns at the guard towers pointed inward, instead of outward?”
11. Internees experienced long-term health problems because of the camps, and children had it the worst.
Internment officially lasted through 1944, with the last camp closing in early 1946. In those years, Japanese-Americans did their best to make lives for themselves on the inside. That included jobs and governance, as well as concerts, religion, and sports teams. Children went to school, but there were also dances and comic books to keep them occupied. But the effects of their internment were long-lasting.
There have been multiple studies of the physical and psychological health of former internees. They found those placed in camps had a greater risk for cardiovascular disease and death, as well as traumatic stress. Younger internees experienced low self-esteem, as well as psychological trauma that led many to shed their Japanese culture and language. Gwendolyn M. Jensen’s The Experience of Injustice: Health Consequences of the Japanese American Internment found that younger internees “reported more post-traumatic stress symptoms of unexpected and disturbing flashback experiences than those who were older at the time of incarceration.”
12. A congressional panel called it a “grave injustice" ... 40 years later.
It wasn’t until 1983 that a special Congressional commission determined that the mass internment was a matter of racism and not of military strategy. Calling the incarceration a “grave injustice,” the panel cited the ignored Munson and Ringle reports, the absence of any documented acts of espionage, and delays in shutting down the camps due to weak political leadership from President Roosevelt on down as factors in its conclusion. The commission paved the way for President Reagan to sign the Civil Liberties Act, which gave each surviving internee $20,000 and officially apologized. Approximately two-thirds of the more than 110,000 people detained were U.S. citizens.
