Why are there literally hundreds of WW2 Nazi movies, but only a handful of ones about the Japanese?

I feel like there are probably more WW2 Nazi movies than any other genre. by comparison I can only think of may be 5 or 6 about the Japanese .

Why such the disparity?

For one it's a bit disingenuous and disrespectful to portray WW2 as a purely European conflict. And from a strictly entertainment standpoint, you could write up a million different scripts that would put Private Ryan to shame.

Also, the few movies I have seen about Japanese in WW2 tend to portray them as noble warriors when in reality they were every bit as evil and diabolical as the Nazis, and committed some of the worst atrocities of the last hundred years.

Their treatment of POWs was also probably the worst fates suffered during any US military war. They would literally mass execute captured soldiers and sailors, often by beheading....

Why is there no Inglorious Bastards Japanese version to date?
