Definitions of Japanese war crimes: There are differences from one country to another regarding the definition of Japanese war crimes.  War crimes have been broadly defined as violations of the laws or customs of war, which include crimes against either enemy combatants or enemy non-combatants.  War crimes also included deliberate attacks on citizens and property of neutral states as they fall under the category of non-combatants, as at the attack on Pearl Harbor.  Military personnel from the Empire of Japan have been accused and/or convicted of committing many such acts during the period of Japanese imperialism from the late 19th to mid-20th centuries.  They have been accused of conducting a series of human rights abuses against civilians and prisoners of war (POWs) throughout east Asia and the western Pacific region.  These events reached their height during the Second Sino-Japanese War of 1937–45 and the Asian and Pacific campaigns of World War II (1941–45).
