Image credit: Daniel K. Inouye Institute December 7, 1941Martial Law is Declared in HawaiʻiAmid rising tensions in the Pacific during the second World War, the Japanese Imperial Army launched a surprise attack on Pearl Harbor, Oʻahu, Hawaiʻi. This devastating event left 2,403 people dead and the naval fleet in tatters. Mere hours after the attack, martial law was declared in Hawaiʻi, and Japanese and European citizens were immediately arrested, guilty of nothing aside from looking like the enemy, although the vast majority targeted were Japanese. The detainment of American civilians under martial law was a contrast to that of the detainment of Japanese Americans on the mainland who were forcibly removed under Executive Order 9066.

Used primarily as a transfer center to continental camps or other camps in Hawaiʻi, up to 450 residents and dozens of prisoners of war were imprisoned here at its peak. This internment camp was in operation for fifteen months while Honouliuli was being constructed on the west side of Oʻahu. Sand Island was often considered the worst experience for many detainees due to camp conditions, inhumane practices, and weather.
There were many different types of incarceration sites in Hawaiʻi and on the continent, as Japanese civilians were shuffled across the country often times staying in temporary camps prior to their permanent site of incarceration. It is important to distinguish between these sites and understand their differences.

Honouliuli saw around 4000 POWs and 400 citizens imprisoned at any given time. Most of the POWs were from Korea, Japan, and Okinawa, with a few being German and Italian.
A small number of women were incarcereated at Honouliuli where they were kept in a separate compound as the men. Americans who were incarcerated were selectively chosen because they were influential to the Japanese communities (Japanese language teachers, priests, politicians, etc.) Learn MoreLife in Honouliuli Internment CampJanuary 27, 1946Honouliuli Internment Camp ClosesAfter three years in operation, Honouliuli internment camp finally closed its doors and released the people held there. Although they returned to their families and communities, re-integration was a long and emotionally painful journey. Unlike the mainland where entire families were interned together, only a select group of citizens were interned. Upon arriving home, they were often met with suspicion for being taken, born out of the assumption that if you had been taken you must be a traitor.
Prisoners of war were repatriated to their home countries. Some had found themselves partners and decided to return to or stay in Hawaiʻi to begin families and start anew. The land where Honouliuli once stood was eventually leased to farming companies. Decades would pass before anyone would realize what had taken place there. Learn MoreWho Was Interned at Honouliuli?2002Site of Honouliuli is RediscoveredThere were many on Oʻahu who knew of Honouliuli's existence, with articles and books naming it as the internment site on Oʻahu, including Ganbare! by Patsy Saiki and Waipahu at War by R.H. Lodge. However, the exact location of where the camp once stood remained a mystery.
One day in 1998, a volunteer of the Japanese Cultural Center named Jane Kurahara answered the phone to be met with a question from a local news station asking where the internment camp on Oʻahu had been. The news station was planning on airing the movie Schindler's List and wanted to concurrently highlight Oʻahu's internment site. At the time, the cultural center was not even aware of an internment site on Oʻahu at all. That phone call kicked off a years long search for the exact site of Honouliuli. It was found with the help of local farmers who recognized the aqueduct in the historical photos four years after the search began. Honouliuli had been found, never to be forgotten again. February 24, 2015Honouliuli Declared a National MonumentFor several years, the Japanese Cultural Center of Hawaiʻi managed and preserved the site. They partnered with archaeologists to uncover the aqueduct, the historic rock wall, and the foundation to what was once the mess hall, amongst many other artifacts. People began to recognize the historical significance of Honouliuli, and with the help of political figures in the community along with local organizations like Historic Hawai‘i Foundation, the Japanese Cultural Center of Hawai‘i, UH West O‘ahu, and others, they publicly advocated for the permanent protection of the park. President Obama historically signed Honouliuli into National Monument status after this grassroots movement, officially making it a National Park. The park service, with the help of the community and local organizations, continues to preserve and protect this historically significant site.
