> I agree that the well known works are usually the better productions, but that detail is wrong. Crunchyroll puts out almost everything that's currently being released

Japan produces a lot more media than just anime, the west does not see most of it. When was the last time you saw a live action Japanese procedural crime show localized to English? Or really any live action Japanese shows that aren't something like Kamen Rider or Godzilla?

Also, arguably the only reason Crunchyroll even exists today is because of dedicated fan subs making Japanese media available for decades

That's true, my mind just instantly jumped to anime because of the word fansub.

I think most people would also agree that anime, manga (and games as a distant third) are the main cultural exports of Japan, while life action movies/series are often centered around American productions

Arguably? Crunchyroll started as a pirate streaming site that hosted fansubs before they went legit.
