World War II in Asia began earlier—and was far darker.

When did World War II really begin in the Pacific? According to historian Jenny Chan, the answer isn’t 1941 and Pearl Harbor. It’s 1931—and the consequences reshaped Asia long before Europe went to war.

In this powerful and unflinching episode of History Rage, Paul Bavill is joined by Jenny Chan, historian, author, and co-founder of Pacific Atrocities Education, to expose the forgotten atrocities of the Second World War in Asia. From the Mukden Incident and the invasion of Manchuria to the Rape of Nanjing and the horrors of Unit 731, this episode confronts the systemic violence that began a decade before Pearl Harbor—and challenges the Western narrative of WWII.

Jenny argues that framing the Pacific War as starting in 1941 erases millions of Asian victims. Japan’s occupation of Manchuria in 1931 marked the beginning of large-scale imperial expansion, biological warfare experimentation, forced labour, and state-sponsored sexual slavery. The brutality of the Nanjing Massacre in 1937 shocked even foreign observers. Meanwhile, Unit 731 conducted human experimentation on an industrial scale—research later shielded from prosecution in exchange for scientific data.

This episode explores:

Why WWII in Asia began in 1931, not 1941
The Mukden Incident and the failure of the League of Nations
The Nanjing Massacre and its global implications
Unit 731 and Japan’s biological warfare programme
Forced labour, “comfort women,” and racial ideology
Why many perpetrators avoided justice after 1945
How the war’s end triggered civil wars and Cold War conflicts across Asia

Jenny also explains how Cold War politics reshaped justice in Asia, why some alleged war criminals returned to positions of power, and how unresolved trauma still shapes East Asian geopolitics today.

This is essential listening for anyone interested in World War II history, Pacific War history, Japanese imperialism, war crimes, or the global consequences of empire.
