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

Yeah, which is why in my original post I wrote:

"It's important to recognize that any discussion about Japanese media outside of Japan is more or less only receiving the media that Japan is exporting to the world"

Which is a really just a long winded way of saying "The majority Japanese media we are exposed to is anime, manga and games"
