Honouliuli Internment Camp is located in Hawaii

The Honouliuli Internment Camp, Hawaiʻi's largest and longest-operating internment camp, opened in 1943 and closed in 1946. Located near Waipahu on the island of Oʻahu, the site was designated Honouliuli National Monument by Presidential Proclamation on February 24, 2015 by President Barack Obama. The internment camp held 320 internees and also became the largest prisoner of war camp in Hawai‘i with nearly 4,000 individuals being held.^[5] Of the seventeen sites that were associated with the history of internment in Hawaiʻi during World War II, the camp was the only one built specifically for prolonged detention.^[6][7][8][9] As of 2015^[update], the new national monument is without formal services and programs.^[10]
