How were the war crimes carried out by Germany and Japan differentiate with one another?

Hi Indy and Crew!

War crimes during WWII have piqued my interest and I found out about Unit 731 when I took a WWII course a couple of years ago. I have common knowledge of the war crimes and atrocities committed by Nazi Germany but I know little of Imperial Japanese war crimes and atrocities. Is there a difference between these two governments on how they carried out these war crimes? Which one was the most severe or grievous towards POWs or civilians?


I think part of the difference was simply due to the fact that Japan had a smaller industrial base at the time, so it faced greater difficulties when trying to commit mass-killings and genocide.
