During WWII, Japanese and Nazi doctors committed heinous experimental medical atrocities. Yet, those performed by the Nazi doctors were deemed “crimes against humanity,” whereas those performed by Japanese doctors were disregarded despite the many similarities. The doctors in both countries who carried out diabolical experiments regarded their victims as sub-human, not worthy of living.

From what I’ve understood from reading writings of people who fought in both Theaters. The Germans were considered the most “Civilized” of the two. Civilized isn’t the best word choice. But it better describes the differences between the two.
In fact people from one theater could often struggle to understand people who fought in the other. Because the enemies were rather dramatically different.
Cannibalism of both Civilians and POWs by Japanese forces wasn’t an isolated occurrence for instance. It wasn’t widespread. But still was disturbingly frequent.
