"Don't look. Don't listen. Don't tell. That was the golden rule of the unit," Shinozuka said.
The initial training he had to undergo was to learn how to produce germs and cultivate fleas, and the first germs produced in mass quantities were used in the Nomohan Incident between Japanese and Soviet near the Chinese and Mongolian border in 1939, he said.
The Soviet forces defeated the Japanese army in the military conflict that took place from May to September, and the defeat was a major setback for those advocates in the army who promoted confrontation with the Soviet Union rather than with the United States.
Unit 731 was active from around 1936 in the former Manchukuo, a puppet state that the Japanese controlled from 1932 to 1945 in the northeastern Chinese region traditionally called Manchuria.
Shinozuka said he himself was involved in vivisections, and that people who were killed for experiments were called "logs" or "maruta" in Japanese.
"We said in the unit we chop one log, two logs...human beings were synonymous to logs...what I was involved in were very serious war crimes," he said.
