Premise: Japanese Devils (or Riben Guizi 日本鬼子 ) is a Japanese documentary about the war crimes committed by the Imperial Japanese Army between 1931 and 1945. The documentary is a series of interviews with 14 Japanese veterans of the Second Sino-Japanese War who recount rape, massacres, bio-experiments, and cannibalism. The accuracy of these interviews is contested by Japanese nationalist critics.
Hypothesis: Japanese Devils is not in English.
