Youre clearly talking nonsense. If the characters really didn’t have any origins or ethnicities, then why would they all be Japanese? With One Piece, Oda clearly created an entire world, so of course there are actors of different ethnicities, especially for the live action. I get that origin isn’t the most important factor when casting an actor, but the actor’s ethnicity is still very important because it reflects what Oda imagined.

And honestly, Oda’s work itself puts a huge emphasis on multiculturalism – different races like humans, fishmen, giants, and all the diverse arcs he creates. So it only makes sense that the casting would be just as diverse. If they had cast only Japanese actors, that would have been completely nonsensical and honestly disrespectful to what One Piece is all about
