Before World War II, the FBI had dossiers on many German, Italian, and Japanese immigrants. Immediately after Pearl Harbor, thousands of them were arrested and sent to "temporary detention centers" and internment camps throughout the country. Learn about these men and women, focusing on the Japanese immigrants held at Sharp Park and Angel Island in the Bay Area. Newly digitized documents available online create new opportunities to learn about their stories.

Key points and insights

In this compelling educational session hosted by Legacy Family Tree Webinars, renowned researcher Grant Din sheds light on a poignant and often overlooked chapter of American history: the World War II internment of Japanese immigrant "enemy aliens" in the San Francisco Bay Area. Focusing primarily on detention facilities at Angel Island and Sharp Park, the presentation explores the profound impact of wartime policies on families and individuals who were legally barred from obtaining U.S. citizenship due to restrictive historical naturalization laws. For family historians, this webinar provides invaluable historical context, illustrating how federal restrictions reshaped lives and demonstrating how an array of administrative records can be utilized to reconstruct complex wartime journeys and uncover deeply personal narratives.

  • Navigating Separate Wartime Jurisdictions: Viewers will learn that the Department of Justice managed distinct confinement facilities separate from civilian relocation camps. Facilities like Angel Island (militarily known as Fort McDowell) and Sharp Park generated unique custodial files, photographs, and internment cards that require specific archival search strategies.
  • The Legacy of Exclusionary Legislation: The presentation highlights how the historical interplay of the Gentlemen's Agreement, the picture bride system, and the Naturalization Act of 1790 left Japanese immigrants vulnerable to automatic classification as enemy aliens upon the outbreak of war, initiating a difficult odyssey across multiple continental camps.
  • Preserving History Through Personal Artifacts: A unique insight involves the power of alternative primary sources, such as censored wartime letters or the extensive camp sketches and diaries of artist George Hoshida, emphasizing how personal creative works and prompt oral histories can fill critical gaps left by official government records.
