Japanese Surrendered Personnel

Japanese Surrendered Personnel (or JSP) is a designation for captive Japanese soldiers (similar to Disarmed Enemy Forces and Surrendered Enemy Personnel). It was used in particular by British Forces referring to Japanese forces in Asia after the end of World War II.

Military and other forced labor
The JSP were until at least 1947 used for enforced labor purposes, such as road maintenance, recovering corpses for reburial, cleaning, preparing farmland etc. Early tasks also included repairing airfields damaged by Allied bombing during the war and maintaining law and order until the arrival of the British forces of occupation.

After the war the U.K. quickly worked to regain control of its Colonial empire territories, and also worked to ensure that the Dutch and French could regain control of their colonial empires. Due to British manpower shortages in the combat against the local resistance fighters who sought national independence, JSP were often pressed into combat service alongside British occupation troops. Louis Mountbatten took on 35,000 Japanese troops into his command in Indonesia. Retaining their wartime organisation and led by Japanese officers they had to fight alongside the British, with one Japanese even being recommended for the Distinguished Service Order as early as November 1945. The recommendation was done by General Philip Christison for Japanese battalion commander Major Kido. Other examples of action include the Japanese company led by Captain Yamada that had to fight their way into Magelang to assist the British; Japanese Kempeitai (military police) used to guard camps in Buitenzorg, Japanese artillery units used for offensives in Bandung, and the Bandoeng garrison that was reinforced by 1,500 armed Japanese. Japanese saw action in Semarang, Ambarawa, Magelang.

Being aware of the sensitivity and hypocrisy of using Japanese troops for the purpose of by force restoring the European colonial Empires against the wishes of the people, the Americans and British worked successfully to conceal the extent of Japanese involvement in this post-war activity.

Legality of retaining JSP
The JSP term was invented by the British so that they would not have to comply with the requirements of the Geneva Convention vis-à-vis Prisoners of War. "The retention of JSP by the British forces was carried out in spite of the repeated questioning of its validity by the American side."

Repatriation of JSP
However, at the same time that they questioned the British use of the JSP designation, the US made use of up to 80,000 JSP in the Philippines for the duration of 1946, at one time even lowering the area priority for shipping and rerouting shipping to the British South East Asia Command to slow the rate of repatriation.

Relevant publications
Several memoirs and other works relevant to the issue have been published. The most famous in Japan, which has been translated into English, is that by Aida Yuji, ''Prisoner of the British. A Japanese Soldier’s Experience in Burma''.
