On the issue of people not caring yeah Japanese political apathy is a double edged sword(pun not intended), it makes it incredibly easy for the neoliberal capitalism system to perpetuate and strengthen itself through the traditional gender and social roles, but it also means people inherently give up and don't go back to question these old issues, the WW2 issues are settled, for the average Japanese they don't care because it means more "politics" which is just the same old same old.

The fascist-nationalist elements that powerful enough to dictate Japanese policy are not watching anime anyway. If you even try to make this into accessible media like manga and stuff it is even worse, like why on earth would you expect some high school student to give a shit about an island dispute from 100 years ago?

Literally the "made/designed by committee" shit in real life, probably the most obvious and clear example of someone being out of touch with reality but pushing ahead anyway.
