As far as the Japanese running directly into machine gun fire there should be an understanding of the chain of command at the time. There were officers and soldiers and the soldiers did what they were told without question, IOW they were a POS and and dying in battle was an honor. Google 'issen gorin'.
Yup, exactly
for those to lazy: "issen gorin" was the price of a postage stamp. It refers to the draft cards sent to the conscripts. They were treated like shit. They were expected to live off the land, rape, kill everything and eat other people. All of this was to instill the "fighting spirit." A book that describes this rather well that comes to mind is the book "Flyboys" by the author of Flags of our Fathers. Just a note: While it is about American Airmen who went down near Iwo Jima (and were captured on an island next to it called Eta Jima that was never invaded, but skipped over), it delves a lot into the training of the Japanese soldiers.
Terrible things were done by the Japanese, especially towards the civilians in wherever they were invading. I'll share some that particularly stick in my mind as especially impacting.
1. A Japanese patrol moves into a town in China. They are poorly fed, having to take anything they want to eat from a populace who doesn't have any food. Meat is impossible to find. They kill all of the males, old women, and most of the children. The women who were of an attractive age were raped. I don't remember the exact term, but it was the equivalent of "pleasure to rape". Then most of those women were killed. The soldiers then stripped meat from them. Particularly the thighs. They ate this. The Japanese soldier recounting this said it was standard practice, and explained the best paces to get and how to prepare it right, but I'll spare you all those details.
2. The same soldier eventually ended up on Eta Jima. The airmen who were shot down there were captured. He recalls how the officers then decided the airmen needed to be killed. They selected soldiers who lacked "fighting spirit" to do the executions. One of them is described, and he was basically a geek (kind of like us) who joined the navy so he wouldn't have to do terrible things in the army. He worked with communications, and had worked with one of the American Airman as he spoke English (the airman was forced to help with their radios). After this, the surgeon was ordered to remove the livers, hearts, thighs, and a couple other organs iirc, which were then cooked in a traditional manner and fed to the commanders and those troops who lacked "fighting spirit". I believe the manner was taking small chunks and boiling them to half cooked, then in a group cooking them in small pans of hot oil.
There are more, but I don't feel like sharing. They did hideous things. Sure the holocaust was terrible, but when compared to the horrible things the Japanese did it barely holds a candle. The tortured everyone they conquered, forced women into "pleasure houses", killed and ate other people, executed anybody associated with any kind of resistance, killed someone when they were bored, mutilated bodies (ie, hacking off a penis and placing it in the still living victim's mouth).
People in Asia still don't forgive the Japanese for the things they did. There's a reason Japan is scared of a nuclear N Korea more than the South Koreans, and why North Korea likes to push the Japanese's buttons. The Chinese still have animosity towards Japan for this.
cliffs for those who want them:
-issen gorin=conscript Japanese soldier who was encouraged and forced to do terrible acts
-Read 1 and 2, I can't summarize them and get the whole point accross
-Japanese atrocities > holocaust, by a lot in lives and atrocities.
-People is Asia still don't forgive Japan
