World War II Japanese American Incarceration: Federal Courts

Despite the numerous violations of their civil liberties, many Japanese Americans and their advocates filed legal challenges to defend their constitutional rights. The decisions rendered in these cases were not always favorable. The courts nonetheless played a crucial role in shaping the narrative and ultimately paved the way for redress and acknowledgement of the injustices faced by the Japanese community in the United States.

Constitutionality of Incarceration

Four test cases raised constitutional questions over the legality of federal policies imposed on Japanese Americans during the war. These cases were particularly important in reconsidering the treatment of underrepresented groups during times of national crisis.

Refusal to Comply with Curfew

Supreme Court (RG 267): 

  • Hirabayashi v. United States, 320 U.S. 81 (1943), no. 870 October Term 1942

Summary: Minoru Yasui and Gordon Hirabayashi were prosecuted and convicted together. The verdict upheld the curfew and exclusion orders enforced within the designated military area. While the Court ruled on the constitutionality of the curfew order, it reserved judgment on the exclusion issue for the Koretmatsu case. In the 1980s, these charges were vacated through petitions for a writ of error (coram nobis).

Summary: Ruled that “concededly loyal" citizens could not be detained without cause. The Court's unanimous decision in Endo offered the federal government a shield to avoid accepting responsibility in denying due process and constitutional rights to its own citizens. The case paved the way for the end of mass confinement and the lifting of exclusion orders.

Draft Resistance

Shigeru Shige Fujii's Prison Admission Summary

Shigeru Fujii's Prison Record (National Archives Identifier: 342714145)

Among the approximately 300 Japanese American men prosecuted for refusing or aiding draft evasion, nearly all were convicted and imprisoned. On December 23, 1947, President Truman signed 

Proclamation 2762 and granted full pardons to these men (along with other conscientious objectors). Those who were still young enough for the draft after the war would go on to serve in the Korean conflict.

Related prison records can be found in Record Group 129 and in the series, “Inmate Case Files, July 3, 1895–November 5, 1957” (National Archives Identifier: 571125) for those sent to the Leavenworth Federal Penitentiary and in the series, “Case Files of Japanese American Prisoners, 1944–1946" (National Archives Identifier: 2675080) for those sent to the McNeil Island Federal Penitentiary. 

The following is a sample list of cases organized by the War Relocation Authority (WRA) camp. Draft resistance did not result in criminal prosecution at every camp.

Limitation of Martial Law

Supreme Court (RG 267): Duncan v. Duke Kahanamoku, 327 U.S. 304 (1946), no. 14 October Term 1945

Court of Appeals (RG 276): Ex parte Duncan, 9th Circuit (1944), no. 10763

District Court (RG 21): Ex Parte Lloyd C. Duncan, District of Hawai’i, Habeas Corpus no. 298.

Summary: Ruled that trials of civilians by military tribunal were unjustified. It also concluded that martial law in Hawai’i could not supplant all civilian laws, and that the military had to respect the constitutional rights of individuals, even during wartime. Although neither party in the case were of Japanese descent, this case was decided on the heels of Hirabayashi and Korematsu, and some justices issued opinions that also addressed the racialized wartime policies inflicted on Japanese Americans.

Involuntary Deportation and Renunciation

Following the end of the war, the government sought to expel Japanese persons detained in the camps, including U.S. citizens and those taken from Latin America, through a renunciation process and deportation proceedings. Lawsuits were filed, both individually and as class actions, aimed at reinstating U.S. citizenship and preventing mass removal.

Renunciation Cases

Court of Appeals (RG 276): 

  • Acheson v. Miye Mae Murakami et al., 9th Circuit (1949), no. 12082

  • Kaname Furuya v. Clark, Northern District of California (San Francisco), Civil no. 25295
  • Tadayasu Abo v. Williams, Northern District of California (San Francisco), Civil no. 25296
  • Kaname Furuya v. Williams, Northern District of California (San Francisco), Civil no. 25297

Summary: Class action suits filed to prevent involuntary deportation, and full restoration of citizenship for the thousands who had renounced, charging that they had been deceived or coerced under the Renunciation Act of 1944. In lieu of oral testimonies, the court required individual affidavits to reestablish their citizenship; this time-consuming process lasted until 1967, when the last final judgment was issued.

Japanese Peruvian Internees

District Court (RG 21): 

  • In re Iwamori Sakasegawa, Northern District of California (San Francisco), Civil no. 26139
  • In re Chika Yamasaki, Northern District of California (San Francisco), Civil no. 26140

Summary: Contending that they were kidnapped by U.S. military police, Japanese Peruvians filed test suits (writs of habeas corpus) in 1946 to prevent deportation to Japan. The federal government agreed to suspend expulsion, reclassified them as resident aliens and allowed them to stay in the United States. A small number of internees were able to return to Peru.

Reinstatement of U.S. Citizenship

American-born Japanese who were stranded in Japan during the war were confronted with the prospect of expatriation due to their activities abroad. These activities—such as being conscripted into Japan's military, participating in Japanese elections after the war, or holding dual citizenship with Japan—were perceived as inconsistent with their ability to retain U.S. citizenship. Turning to the courts, they sought to have their American citizenship confirmed or restored. Some of these cases also provide detailed descriptions of their lives in Japan just before and during World War II, with a focus on the activities of and climate created by the Japanese police and military. 

The following selection of cases shows how the decisions rendered were contingent on the merits of whether their actions in Japan were voluntary or involuntary. Related applications for repatriation may be also found among naturalization petitions.

Treason

While no large-scale conspiracy of espionage or sabotage was ever uncovered, there were a few Japanese Americans who were convicted of either treason or the lesser offense, the conspiracy to commit treason.

District Court (RG 21): United States v. Wallace, District of Colorado, Criminal no. 10387

Summary: Three Japanese American women (Tsuroko ["Toots"] Wallace, Florence ["Flo"] Otani, and Misao ["Billie"] Tanigoshi) were convicted of the conspiracy to commit treason for helping German soldiers escape from a POW camp.

District Court (RG 21): United States v. Iva Ikuko Toguri D’Aquino, Northern District of California (San Francisco), Criminal no. 31712

Summary: D'Aquino was convicted of treason for allegedly undermining American morale while working as a radio broadcaster for Radio Tokyo. In 1977, due to insufficient evidence and prosecutorial misconduct, she was pardoned and her citizenship was restored. The case raised questions over the definition of treason and the limits of free speech during wartime.

Reparations

The post-war redress movement was long and hard-fought. Led by Japanese American activists, the campaign sought large-scale financial compensation for lost property, and public recognition and apology for the forced removal and confinement. While reparations were pursued through Congress, claims were also filed in the federal courts. The passage of the Civil Liberties Act in 1988 eventually provided reparations to camp survivors who were U.S. citizens and permanent residents. On the other hand, Japanese Latin American internees achieved only a partial victory with a settlement in 1999, and their fight for equal compensation continues to this day.

Cases Related to the Japanese American Claims Act, July 2, 1948

U.S. Court of Claims (RG 123):

  • William S. Koda v. United States, U.S. Court of Claims, no. 329-57
  • Edward K. Koda v. United States, U.S. Court of Claims, no. 330-57

Summary: Sample cases. Under Public Law 80-886 (80 H.R. 3999), Japanese Americans could seek compensation for their losses up to $2,500 (later increased to $100,000 for remaining claims), through the Department of Justice. Additional claims could be filed in the Court of Claims for amounts beyond this limit or for dismissed claims. Despite efforts to simplify the process in subsequent legislation, the overall compensation and number of claimants remained unfairly low. Only with the passing of the 1988 Act, did they receive a more substantial redress, including a public apology. To search for additional claim suits, see series, General Jurisdiction Case Files, 1855–1970 (National Archives Identifier: 2733380) and Index (National Archives Identifier: 594766).

Claims Filed Against the Office of Alien Property Custodian (APC)

Supreme Court (RG 267): Honda et al. v. Clark, 386 U.S. 484 (1967), no. 164 October Term 1966

Court of Appeals (RG 276): 

  • Honda et al. v. Clark, District of Columbia Circuit (1969), no. 22188 and 22193
  • Aratani et al. v. Kennedy, District of Columbia Circuit (1963), no. 16808
  • Harue Sakamoto v. Kennedy, 9th Circuit (1961), no. 16770

  • Sekiyo Nishikawa et al. v. Brownell, Jr., Central District of California (Los Angeles), Civil no. 18267
  • Kazuichi Hashimoto v. Markham, Central District of California (Los Angeles), Civil no. 5739

Summary: Sample list of cases. During and after the war, claims were filed in federal courts seeking the recovery of property that had been seized by the APC or requesting compensation from the proceeds of any property sold. These assets include bank deposits, land, and businesses. Many of these cases were “dismissed without prejudice.”

Class Action Redress Lawsuit

Supreme Court (RG 267): United States v. Hohri et al., 482 U.S. 64 (1987), no. 86-510

Court of Appeals (RG 276): Hohri et al. v. United States, District of Columbia Circuit (1986), no. 84-5460

District Court (RG 21): William Hohri et al. v. United States, District of Columbia, Civil no. 83-0750

Summary: Class action suit that sought compensation for injuries sustained by the forced removal and incarceration during World War II. The case was ultimately dismissed after Congress passed the Civil Liberties Act of 1988.

Reparations Claims by Japanese Latin Americans

U.S. Court of Federal Claims (RG 502): Carmen Mochizuki et al. v. United States, 43 Fed. Cl. 97 (1999), no. 97-294C

Summary: This class action settlement provided a presidential apology and $5,000 reparation payment to Latin Americans of Japanese descent who had been excluded from the Civil Liberties Act of 1988. The settlement also underscored its shortcomings: due to inadequate funding provided by the Act, there was no guarantee of redress payments. And those who declined payment or were excluded from the initial lawsuit continue to advocate for reparations to this day. NOTE: As of 2024, case 97-294C has not yet been transferred to the National Archives. Please contact the U.S. Court of Federal Claims for access.
