Well, tragically, I get the impression from multiple sources of an ongoing conflict between the western military ideal in Japan, and the Bushido spirit ideal.
There were certainly learned, and qualified, generals in Japan. They accomplished alot! But there also seemed to be a sense that if they weren't accomplishing RIGHT THEN, that they were doing something wrong and should try harder.
This is what led to the Japanese Army (or Navy, probably) following a well thought-out and strategically/tactically based policy... Then getting an itch for glory or combat or whatever, and just doing a full-out, dangerous charge!
I do not understand it, but it seems to come up again and again in the histories I've read. The impulse to seek honor far above the preservation of one's own life seems very strong, such that it often overwhelmed good military sense. And in the end it killed the Japanese Army and Navy.
Just my observations, since you asked.
