Immigrants from more than 80 countries were processed at the Angel Island Immigration Station between 1910-1940, including approximately 175,000 Chinese, most who were detained for months and even years at a time. Up to 85,000 Japanese were admitted through Angel Island, and the barracks housed Nikkei detainees from Hawai‘i during World War II, as well as Japanese POWs. Recent additions include the Angel Island Immigration Museum and a new permanent exhibit in the former World War II Mess Hall entitled “Taken From Their Families: Japanese American Incarceration on Angel Island During World War II.” Guided tours are provided by park staff and volunteers.
