Marutas of Unit 731

Unit 731, under Dr. Ishii Shiro, conducted horrific human experiments during World War II, masked as public health initiatives. Targeting Chinese patriots, civilians, Russians, and allied POWs, the unit operated with the Kempeitai's support, capturing individuals for experimentation. While the exact number of victims remains uncertain due to evidence destruction post-war, estimates suggest between 3,000 and 250,000 innocent lives were affected. The atrocities were performed by top medical talent, revealing a dark chapter in Japan's wartime history.
