This film depicts the Japs as noble warriors.

"Japs"= Japanese people= race (or specifically ethnicity of a race)

"Nazis" = typically German (and also, yes, could be considered ethnicity and/or nationality) but is rather a group of people in a MOVEMENT rather than simply just a race group = not a race ("japs" refer as a term to a whole race of people that paints them all as bad, while nazi is an official term that is used to talk about heinous acts committed by specific large groups not just limited to race ((however, of course, it's almost always white people)) not supposed to be used as an offensive term (((though of course can be used as an insult)))

There is a difference and it's a huge generalization trying to compare the two

Anyways, to me it seemed like the Japanese people were more portrayed as bad than good in this movie.

Schindler’s List has a literal Nazi as the hero.

Also the two surrendering Wehrmacht soldiers being mercilessly gunned down in Saving Private Ryan.
