Shiro Ishii was born in Shibayama Village, Sanbu District, Chiba Prefecture, Japan. He studied medicine at the Kyoto Imperial University. In 1922, after joining the Japanese Army, he was assigned to the 1st Army Hospital and Army Medical School in Tokyo, Japan. In 1924, he returned to Kyoto Imperial University for post-graduate studies. Between 1928 and 1930, he traveled to the West, researching biological and chemical warfare from the experience from WW1. In 1932, he was chosen by the Japanese Army to begin biological warfare research at the Zhongma Fortress in Beiyinhe, which was outside of Harbin in Manchuria, northeast China (Manchukuo). In 1935, Ishii shut down the Zhongma Fortress due to a security breach, and shortly after set up a very large facility in Pingfang, which was 24 kilometers south of Harbin; the new facility had 150 buildings over six square kilometers of land, and the facility was publicly known as a water purification research center. In 1940, he was appointed the Chief of Biological Warfare Section of the Japanese Kwantung Army, while at the same time holding the title of the head of the Bacteriological Department of the Japanese Army Medical Academy. In 1941, his unit was formally renamed the Epidemic Prevention and Water Purification Department of the Kwantung Army, also known as Unit 731. In 1942, he began conducting tests of germ warfare agents on Chinese prisoners of war, Chinese civilians, and in combat. Some of the germs he experimented with included bubonic plague, cholera, and anthrax, among others. Between 1942 and 1945, he was the Chief of the Medical Section of the Japanese First Army. In 1945, as the end seemed near, Japanese troops attempted to destroy Unit 731's headquarters to destroy all evidence; as part of this effort, Ishii ordered 150 remaining subjects killed.

After the war, Ishii was arrested by American troops. As with all other Unit 731 leaders, he was granted immunity by Allied leaders in exchange for their knowledge in biological and chemical warfare. According to Cambridge University lecturer Richard Drayton, Ishii moved to Maryland, United States to continue his research of biological weapons, but his daughter Harumi noted that Ishii remained in Japan after the war. He passed away from throat cancer in Tokyo, Japan in 1959.
