Honouliuli National Historic Site near Waipahu on the island of Oahu, is the site of the largest and longest-operating internment camp in Hawaii. The internment camp was opened in 1943 and closed in 1946, and used to house Japanese Americans (both citizens and non-citizens), Italians, Germans, and other individuals considered to be "enemy aliens" during World War II. The park is currently closed to the public. If you would like learn more about Hono‘uli‘uli when visiting O‘ahu, you can visit the Japanese Cultural Center of Hawai‘i in Honolulu. However, the Honouliuli Preserve is open to the public for hiking and birdwatching.
