Did the Japanese detonate an atomic device just days before they surrendered?
Using once-secret Japanese wartime documents, Japan’s Atomic Bomb offers evidence that Japan had world-class nuclear physicists, access to uranium ore, and cyclotrons to process it.
The Japanese devised an innovative way to deliver the bombs using 400-foot long Sen Toku submarines, capable of carrying and launching airplanes. Only six days after Hiroshima, Japan tested its own atomic device on a small island 20 miles off the Korean coast. The evidence suggests Japan was just weeks behind the United States in the race to build the bomb.
Since the end of WWII, conventional wisdom claimed that Imperial Japan was years away from building an atomic weapon. Japan’s Atomic Bomb shatters that view.
