JAV is a commercial industry; they are out to make money, not to appease social justice warriors or black men.
Those who buy JAV are almost all Japanese men and they are, generally, not turned on by Japanese girls with good looking black men.
Instead they want to see the girls "defiled"(by their own standards) and humiliated.
If black men, one day, win science Nobel prizes and are noted for high intelligence, the number of black men in JAV will be reduced to that of white men.
Still spouting stupidity I see
