This podcast episode delves into the dark history of Unit 731, a secret Japanese detachment that committed medical atrocities during World War II. It explores the rise of ultra-nationalism in Japan, the formation and location of Unit 731, the unethical experiments conducted, the brutal treatment of prisoners, the aftermath and trials, and the ongoing debate on teaching this history to future generations. The revelations about Unit 731's atrocities and their collaboration with the U.S. to obtain information instead of prosecuting them raise important questions about accountability and the long-lasting impact of war crimes.
