Unit 731

Recently, I was watching a Chinese movie named Fist of Fury. The film references Japanese experiments conducted on human subjects. Hoping to learn more, I began reading viewer reviews, one of which mentioned "Unit 731"—a reference that confirmed the historical reality of these Japanese human experiments.

The fact remains that Unit 731 was a covert biological and chemical warfare research unit of the Japanese Imperial Army that performed human experimentation during the Sino-Japanese War and World War II. This operation from 1936 to 1945 was disguised as an epidemic prevention and water purification department. It subjected thousands of prisoners—primarily Chinese, Soviet, and Korean civilians—to horrific medical atrocities. These experiments included vivisections without anesthesia and intentional infections with pathogens such as anthrax, cholera, and bubonic plague. Furthermore, Unit 731 developed and dropped plague-infected fleas and contaminated food and water supplies in Chinese cities and villages, causing epidemics that killed tens of thousands of civilians.

Shiro Ishii

After Japan's surrender in 1945, many of the physicians, scientists, and military personnel—including the unit's commander, General Shirō Ishii—were granted immunity. In exchange, they handed over the data gathered from their human experiments to the U.S. military. For decades, the existence of Unit 731 was denied by the Japanese government. Today, it is widely recognized by historians as one of the most egregious medical atrocities and crimes against humanity.

I’m always alarmed when I learn about such historical events. It underscores the capacity for profound cruelty within human nature. Whether we label these traits as "evil" or view them as inherent components of the individual psyche, history shows us clearly that they are part of our shared nature. While atrocities are frequently attributed to Western nations—particularly the United States, given its global footprint—this capacity appears to exist within every individual and culture.

As my mother would often say regarding problematic human behavior: "What to do?" To be quite honest, I am not sure. Yet, across all religions, there are valuable lessons and teachings about love and human connection. This wisdom has been passed down through generations. If we dared to follow those teachings sincerely, they could truly make all the difference in the world.
