World War II Japanese American Incarceration: Researching an Individual or Family
Getting Started
Although most persons of Japanese descent were incarcerated in one of the ten War Relocation Authority (WRA) incarceration camps, others were placed in camps run by the Department of Justice or the U.S. Army. A number of Nikkei (Japanese emigrants and their descendants) communities residing outside the Pacific Coast were never detained, but may have been documented by the federal government in other ways. Researchers should also consider accessing personnel records for those who served in the military or were employed by the federal government.
Knowing a person’s background will help determine what kind of records may be available. Consider starting your research by delving into the individual’s history and examining relevant documents. This initial step will help you collect some basic information such as:
- Name of individual
- Date and place of birth
- Place of residence before incarceration
Provide additional information, if known:
- Name of the camp or camps (for those who may have been transferred between multiple sites).
- These will include camps administered by the War Relocation Authority, Army, and/or the Department of Justice/Immigration and Naturalization Service.
- Name of the head of family and other family members
- Family number
- These were numbers assigned to a family entering the War Relocation Authority camp. While each record was assigned an “Individual Number,” members of one family usually have the same five numbers, with the letter denoting the position of the person in the family.
- Branch of military service
- Federal agency where employed
-
Some individual files have been indexed and are name searchable in the National Archives Catalog. If you are able to locate a Catalog record related to your individual or family, please contact the NARA office identified under the section “Archived Copy.”

War Relocation Authority Camps
War Relocation Authority (WRA) Case Files
The National Archives in Washington, DC, holds the case files of Japanese and Japanese Americans detained in WRA incarceration camps, known as "relocation centers." These camps initially imprisoned persons of Japanese ancestry, both citizens and noncitizens, who were forcibly removed from parts of California, Oregon, Washington, and Arizona that had been designated as military areas. As some Japanese enemy aliens were released from Army and Department of Justice-Immigration and Naturalization Service (DOJ-INS) camps, they were transferred to the WRA sites, where many reunited with their families.
The case files are found in Entry PI-77 22 in Record Group 210, Records of the War Relocation Authority (National Archives Identifier: 891305).
What you will find in these records:
The content of individual case files varies. In addition to including basic identifying information about the individual (such as their name, age, and physical description), case files may also contain:
- Medical records
- Property records
- School records
- Military service information
- WRA camp employment records
- Leave or discharge documentation
- Related correspondence
- Additional information about an individual's family members
Note: Not all case files contain each of these documents.

Starting Your Research
In addition to creating individual and family folders, the WRA collected statistical information upon arrival and near the closing of the camps. This data can be useful for locating information about those incarcerated in WRA camps, including family numbers.
Entering the WRA Camps, 1942
Evacuee Summary Data Cards, 1942–1946 (National Archives Identifier: 1055737): These computer punch cards consist of basic information gathered soon after Japanese American individuals and families entered the WRA camps. These data cards are particularly useful to locate individuals who left the camps early during the war (to enlist in the military, to work in the civilian workforce, or other), before the Final Accountability Rosters were created in 1944.
Data from the computer punch cards can be searched electronically via the Access to Archival Databases (AAD).

Closing the Camps, 1944–1946
Final Accountability Rosters of Evacuees, 1944–1946 (National Archives Identifier: 1055789): These rosters were created as the WRA camps prepared to close and contain valuable information including the trajectory of a person’s incarceration from the method of original entry (from an "assembly center," other institutions, Hawai'i, another "relocation center," or birth) to the type of final departure (indefinite leave, internment, repatriation/expatriation, segregation, relocation, or death). While these rosters are useful to locate individuals who were still in the WRA camps near the end of the war, including those transferred from DOJ-INS camps, the rosters will not include those who left earlier in the war.
- Digitized microfilms are arranged by WRA camp. Name searchable indexes are also available from Ancestry.com.
**Both the Final Rosters and Data Cards have been indexed into a combined Names Registry developed by Densho.org.

Immigration (INS) Case Files
After receiving an order from the U.S. Attorney General for the internment of an enemy alien, the person was sent to an Enemy Alien Internment Facility run by the Immigration and Naturalization Service (INS) (Record Group 85). The INS oversaw all the Department of Justice and many of the Department of State internment facilities. INS field offices also maintained case files for the initial arrests of enemy aliens.
The INS ran twelve permanent enemy alien internment facilities:
INS records also include files from the Tule Lake Segregation Center, covering the immediate post-war period when the camp held those who renounced their U.S. citizenship, and those seeking repatriation and expatriation to Japan.

Military and Civilian Service
Because most military branches refused to enlist persons of Japanese descent during World War II, the majority of Nisei (Japanese Americans whose parents emigrated from Japan) served in the U.S. Army, while others (both Nisei and Issei [first-generation immigrants from Japan]) were employed in civilian roles including the Office of Strategic Services and the Cadet Nurse Corps. While personnel records may be requested from the National Archives at St. Louis or the National Personnel Records Center, several online name indexes are also available for researchers to search for information.

Renouncing—and Restoring—U.S. Citizenship
Public Law 78-405, commonly referred to as the Renunciation Act of 1944 or the Denationalization Act of 1944, was signed into law on July 1, 1944. This law amended the Nationality Act of 1940 and allowed Americans within the United States renounce their citizenship. The National Archives holds records that document both the application process to renounce and the legal proceedings to restore U.S. citizenship for Japanese Americans.

Post-War Redress and Reparations
The post-war redress movement—seeking financial compensation, and public recognition and apology for the forced removal and confinement—took decades to bear fruit. While the Claims Act of 1948 provided token compensation for lost property, only with the passing of the Civil Liberties Act of 1988 did the formerly incarcerated receive more substantial redress, including a public apology. Records at NARA include case files for claims filed under the 1948 Act, claims filed under the 1988 Act, and testimonies from the public hearings held by the Commission on Wartime Relocation and Internment of Civilians (CWRIC).
Japanese American Claims Act Case Files, under 1948 law
About the Claims
The Japanese American Evacuation Claims Act of July 2, 1948, provided compensation for losses of real and personal property to Japanese American citizens removed from the West Coast during World War II. The vast majority of the approximately 26,550 claims filed were compensated for $2,500 or less. The program was administered by the Justice Department, which later set a $100,000 limit on each claim. Approximately $37 million was awarded.

CWRIC Public Hearings and Testimonies
About the Commission on Wartime Relocation and Internment of Civilians (CWRIC) (Record Group 220)
The CWRIC was set up to review the facts and circumstances surrounding the forced removal and incarceration, and its impact on American citizens and permanent residents.
What you will find in these records
These records reflect the Commission's twenty days of hearings and testimonies from more than 750 witnesses held between July and December 1981, in cities across the country. These witnesses included Japanese Americans and Aleuts who had lived through the events of World War II, former government officials who ran the incarceration programs, public figures, organizations such as the Japanese American Citizens League, interested citizens, historians, and other professionals who had studied the subjects of the Commission's inquiry. Materials also include publications, reports, press releases, photographs, newspaper clippings, and transcripts that relate to the hearings. The transcripts contain many personal narratives that directly capture the intangible losses stemming from the wartime policies by the U.S. government.
