In this episode of Dark Stories, we explore the disturbing history of Unit 731 — a secret biological warfare program operated by the Imperial Japanese Army during World War II.

Hidden in occupied China, Unit 731 conducted human experimentation to develop biological weapons. The program remained secret for years after the war, and its legacy continues to raise ethical and historical questions.
