Shōichi Yokoi (横井 庄一, Yokoi Shōichi, March 31, 1915 – September 22, 1997) was a Japanese sergeant in the Imperial Japanese Army (IJA) during the Second World War, and was among the last three Japanese holdouts to be found after the end of hostilities in 1945. He was discovered in the jungles of Guam on 24 January 1972, almost 28 years after U.S. forces had regained control of the island in 1944.
