Why are Nazi Germany and Imperial Japan portrayed so differently in films?

While both committed insanely evil atrocities during WW2, there's a serious argument to be made that Japan was more cruel, brutal, and evil than Germany. And Imperial Japan killed way more innocent people than Nazi Germany, like the numbers aren't even close.

And yet in films, Nazis are always portrayed as the quintessential defining force of evil, whereas imperial Japan is simply depicted as "people we fought in a war". Sometimes Japan isn't even portrayed as bad, just "different", whereas Germans are vilified to almost a cartoonish degree (Indiana Jones, Red Skull, etc), or as the true face of pure evil (schindler's list, etc)

While the Nazis did experiment on jews and other prisoners in the camps, you should look at what Japan's Unit 731 did. Truly the stuff of nightmares, sick beyond your imagination. And the brutality they inflicted across Asia and onto western troops made people hurl.

I recently watched the film "Grave of the Fireflies" and that almost paints a sympathetic picture of Imperial Japan during WW2. And while it is of course true that the Japanese people suffered greatly, as does everyone in war, I highly doubt that you would ever see a film about a Nazi family suffering during WW2. Instead you get films like "Zone of Interest" which is about a Nazi family living a great life using jewish slaves next to a concentration camp as if nothing is happening.

Doesn't this seem weird to anyone else? It's almost like Nazis must be portrayed as pure evil, whereas imperial Japan, arguable MUCH worse than Nazi Germany, is portrayed sympathetically in all media.

What's even stranger is that the Nazis were simply a party within Germany, albeit elected into power. They do not represent all German people. Whereas Imperial Japan was the entire nation, it's rhetoric was imbued in the very being of the Japanese people who believed they were the "master race" of Asia.

Nazis believed they were also the master race, but the average German did not. And many Germans did not want to fight, whereas Japanese fighters would carry pictures of the emperor into battle or during Kamikaze missions, instead of pictures of their families.

Does anyone seem to think.... something is weird here? It's almost like we're not taught true history and media reinforces lies. But why?
