The Rohwer War Relocation Center was a World War II Japanese American concentration camp located in rural southeastern Arkansas, in Desha County. It was in operation from September 18, 1942, until November 30, 1945, and held as many as 8,475 Japanese Americans forcibly evacuated from California. Among the inmates, the notation "朗和 " was sometimes applied. The Rohwer War Relocation Center Cemetery is located here, and was declared a National Historic Landmark in 1992.
