China Japan History

The Imperial Japanese Military had invaded Shanghai on August 13, 1937, rapidly reducing the once-prosperous city to a pile of burning rubble after three months of brutal urban combat. Countless blazing fires raged throughout the city, some of which had been caused by the fighting, but most had been set by the retreating Chinese Army in a futile effort to stall the Japanese invaders.

Shanghai, known as the Pearl of the Orient, had always been an international center in China was near-total destruction during the Sino-Japanese War. Following the Marco Polo Bridge Incident in 1937, the Japanese headed for its goal, the capital of China, Nanking. Shanghai was a key battleground before they were able to reach the capital of China, which brought on the “Stalingrad on the Yangtze”.

Unit 731 was established during the Sino-Japanese War in Harbin as a covert biological warfare research and development section of the Imperial Japanese Army. Besides human experimentation, they developed lethal biological weapons as an efficient way to win the war against the world. In about a decade of existence, they produced a massive amount of germs enough to kill the world three times. 

During the occupation of Japan after WWII, the US had an important decision to make. Should they hold those responsible for atrocities during the war accountable or should they take the information to advance national interest? The researchers who worked at Unit 731, the biological and chemical warfare research and development unit, were given immunity in exchange for their research data. Unit 731 included factories filled with humans, tested with various diseases, as well as field tests on civilians of the Soviet Union and China.

Though scarcely mentioned in the world of early 21st century politics, Manchuria represented a key region of Asia during the first half of the 20th century. Once the heartland of the fierce Manchu empire, this northeastern Chinese region's rich natural resources made it a prize for nations in the process of entering the modern age, and three ambitious nations in the midst of such a transformation lay close enough to Manchuria to attempt to claim it: Japan, Russia, and China.
