An excellent point, Leo. The Code of Bushido taught that a soldier who surrendered or was captured by the enemy was a contemptable, dishonorable coward who betrayed the Emperor, the Japanese culture and his fellow soldiers. This is the main reason why so few Japanese fell into Allied hands during the Pacific War. They would almost always commit suicide rather than be captured by an enemy they had been brainwashed into believing would torture them to death.
GuerraCivil can find a lot of discussion on this subject over on Axis History Forum (
http://forum.axishistory.com/ ) under Holocaust & 20th Century War Crimes, and I believe a thread dealing with his specific question can be found there, IIRC.
