Japanese

Although thousands of Japanese servicemembers were taken prisoner of war, most fought until they were killed or committed suicide. Of the 22,000 Japanese soldiers present at the beginning of the Battle of Iwo Jima, over 20,000 were killed and only 216 were taken prisoner of war. Of the 30,000 Japanese troops that defended Saipan, fewer than 1,000 remained alive at battle's end. Japanese prisoners of war sent to camps fared well; however, some were killed when attempting to surrender or were massacred just after doing so (see Allied war crimes during World War II in the Pacific). In some instances, Japanese prisoners of war were tortured through a variety of methods. A method of torture used by the Chinese National Revolutionary Army (NRA) included suspending prisoners by the neck in wooden cages until they died. In very rare cases, some were beheaded by sword, and a severed head was once used as a football by Chinese National Revolutionary Army (NRA) soldiers.

After the war, many Japanese POWs were kept on as Japanese Surrendered Personnel until mid-1947 by the Allies. The JSP were used until 1947 for labour purposes, such as road maintenance, recovering corpses for reburial, cleaning, and preparing farmland. Early tasks also included repairing airfields damaged by Allied bombing during the war and maintaining law and order until the arrival of Allied forces in the region.
