Like, half of anime is exactly that. The audience likes being exposed to the culture and things that don’t easily translate. They like learning specific words and concepts that can’t be translated easily “nakama” being important in One Piece for example.

Exactly. Most young peoples in the west nowadays know what "sensei" "-kun/-san/-chan" "kawaii" and so on mean because of mangas.
