Analyse both the contemporary and past trends in anime and decide whether representation of different race of people is required or not considering the fact the amount of liberty an anime creator enjoys. Also, if representation in anime is a need of the hour as many people believe the sheer ridiculousness in shonen anime character style does not require characters to resemble real life human beings.
I think any attempt to discuss racial diversity in anime needs to take into account that the Japanese have their own ideas about what constitutes "diversity." Japan isn't a very racially-diverse nation, so when Japanese anime and manga attempt to depict diversity the discussion tends to center more around things like social and cultural class, or, in some cases, the few minority ethnic groups that exist (like the Ainu, who feature prominently in "Golden Kamuy," for instance). One anime that's rather famous for exploring the various forms of diversity in Japanese culture is "Samurai Champloo." Obviously anime that don't take place in Japan need to be more conscious of different races and cultures than those that do. I also think cultural provincialism is a bigger problem in a lot of anime than racism as such. I've seen anime that were set in "white" nations and featured white characters that still struck me as very insensitive, because the creators make everyone whose opinions matter (and even some who don't) behave and react the same way a Japanese person would. – Debs7 months ago
It could be helpful to examine how genres treat race. For example, historical anime would likely have a limit on which races will be depicted. Also, stereotypes can be a problem in anime. – Jiraiyan6 months ago
