WWII Japanese American detainees return to Minidoka for visit. When Amy Hirasawa, 85, left Idaho 60 years ago after years of internment under the War Relocation Authority, one thing she took with her was her doll named "Blondie" that saw her through the war. Former Japanese American detainee Amy Hirasawa , of Seattle, returned with other World War II prisoners to the Minidoka Relocation Center near Twin Falls last weekend.
