The brutalities included shooting, stabbing, cutting open the abdomen, excavating the heart, decapitation, drowning and punching the body and eye with an awl. Thousands of civilians were buried or burnt alive, or used as targets for bayonet practice, shot in large groups and thrown into Yangtze River. Many soldiers went beyond rape to disembowel women, slice off their breasts, nail them to walls. Not only did live burials, castration, the carving of organs and the roasting of people become routine, but more diabolical tortures were practiced, such as hanging people by their tongues on iron hooks.

Victims were often taken to a proving ground called Anda, where they were tied to stakes and bombarded with test weapons to see how effective the new technologies were. Planes sprayed the zone with a plague culture or dropped bombs with plague-infected fleas to see how many people would die.

The Japanese organized burning of buildings in the city. After they had set fire to buildings using either gasoline or some other flammable chemicals, they hid, waited for and killed people who came to extinguish the fire. Numerous people were killed in this way. Nanjing, once a beautiful historical city, was burned to ashes by the Japanese.

The Japanese invented games of rape and torture, turning murder into sport. Soldiers competed in "Bushido" - KILLING CONTESTS and sent the number of murders back to Nichi-Nichi Shimbun national newspaper in Japan to publish.
