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. He was among the last three Japanese holdouts to be found after the end of hostilities in 1945, discovered in the jungles of Guam in January 1972, almost 28 years after US forces had regained control of the island in 1944.
