Japan's Holocaust combines research conducted in over eighteen research facilities in five nations to explore Imperial Japan's atrocities from 1927 to 1945 during its military expansions and reckless campaigns throughout Asia and the Pacific. This book brings together the most recent scholarship and new primary research to ascertain that Japan claimed a minimum of thirty million lives, slaughtering more than Hitler's Nazi Germany. Japan's Holocaust shows that Emperor Hirohito not only knew about the atrocities his legions committed, but actually ordered them. He did nothing to stop them when they exceeded even the most depraved person's imagination, as illustrated during the Rape of Nanking as well as many other events. Japan's Holocaust will document in painful detail that the Rape of Nanking was not an isolated event during the Asian War but rather representative of how Japan behaved for all its campaigns throughout Asia and the Pacific from 1927 to 1945.

Mass murder, rape, and economic exploitation was Japan's modus operandi during this period, and whereas Hitler's SS Death's Head outfits attempted to hide their atrocities, Hirohito's legions committed their atrocities out in the open. Moreover, whereas Germany has done much since World War II to atone for its crimes and to document them, Japan has been disgraceful with its reparations for its crimes.
