We should just be all one region, one nationality, one language.
Also Japan has a huge culture centered around brand cross promotions for all sorts of media unlike the U.S, so them having a collab with something like KFC isnt anything new. You see stuff like that all the time over there. I kinda wish the US would also do neat cross promo stuff like that for games. I mean it happens sometimes but not to the same level as Japan.
Oh well. I think the easier solution for this is to allow non-JPN players to be able to earn the emote somehow in-game but theres probably some restrictions or brand limitations or contracts or whatever legal mumbo jumbo in place.
