On Dec. 10, 1968, a uniformed man pulled over a bank car in Tokyo. He explained that police had received a warning that dynamite had been planted in the vehicle, which was transporting bonuses for local Toshiba employees. The four passengers got out and watched as the officer crawled underneath.
After a moment he rolled out, shouting that the car was about to explode. When the passengers ran, he got in and drove off.
Thus one man stole 294,307,500 yen in broad daylight, working alone and without harming anyone. It remains the largest single heist in Japanese history. The thief was never caught.
