美国国家公园管理局于2024年7月18日首次向公众开放位于夏威夷的Honouliuli战时拘留营遗址，启动试点公共导览项目[1]。这处隐没于山谷中的遗址见证了美国历史上一段沉痛的过往，如今通过每月一次、限额22人的免费导览向公众揭示其历史[1]。
Honouliuli拘留营于1943年3月开设，1946年关闭，曾是美国最大的战时拘留场所[1]。珍珠港事件发生于1941年12月7日后，军事管制随之控制了夏威夷[1]。罗斯福总统于1942年2月19日签署第9066行政令，之后超过2000名日裔美国人在夏威夷被捕，其中约400人被关押在岛内，其余被送往美国本土营地[1]。这处营地在峰值时关押近4000人，包括被强征入日本帝国陆军的韩国人、冲绳人，以及被怀疑不忠的意大利人、德国人等欧洲裔美国人[1]。拘留者曾称这里为"Jigoku Dani"（地狱谷）[1]。相比之下，在夏威夷，少于1%的日裔居民在战争期间被关押[1]。
2002年，日本文化中心根据拘留者的旧照片和草图确定了遗址位置[1]。该遗址于2015年被奥巴马总统指定为国家纪念地，国会于2019年将其指定为国家历史遗址[1]。首次公众开放已引发广泛关注，超过1800人已登记在等候名单上[1]。
The Honouliuli internment camp, once America's largest wartime detention facility, has opened to the public through guided tours for the first time [1]. Located in a remote gulch on Oahu's Kunia region, the site operated from March 1943 to 1946 and held nearly 4,000 people at its peak, including Japanese Americans, prisoners of war, Koreans forcibly conscripted into the Japanese Imperial Army, Okinawans, and people of European descent suspected of disloyalty [1]. Those detained there called it "Jigoku Dani," meaning Hell Valley [1]. The National Park Service launched the pilot public program on July 18, 2024, offering free monthly tours limited to 22 participants, with over 1,800 people already on the waiting list [1].
The camp's establishment followed Pearl Harbor's attack on December 7, 1941, which triggered military control over Hawaii and mass arrests of Japanese Americans in the islands [1]. After President Roosevelt signed Executive Order 9066 on February 19, 1942, over 2,000 Japanese Americans in Hawaii were arrested; approximately 400 were held locally while the rest were sent to mainland detention facilities [1]. Honouliuli was one of seventeen known wartime detention sites across Hawaii, though fewer than 1 percent of the islands' Japanese American residents were actually incarcerated during the war [1]. The site's location was rediscovered in 2002 by the Japanese Cultural Center using old photographs and sketches drawn by former detainees [1]. President Obama designated Honouliuli as a National Monument in 2015, and Congress subsequently established it as a National Historic Site in 2019 [1].
