Jesus... why are (some) Japanese developers so ignorant when it comes to, well, rest of the globe, don't they want money? I don't understand such mentality.
Given the disconnect of the nature of how the Persona franchise is established globally, it makes sense to split up the messaging.
Japanese audience are exposed to the Persona franchise as a multimedia property with figurines, anime, movies, concerts, games and many more. Furthermore, the core Persona development team are not English-literate, so there's a huge communication barrier. Even Square Enix of all publishers struggle with this and they are far larger than Atlus.
On the other hand, Persona is just a gaming franchise with minor anime offshoots in the rest of the world.
So, it makes sense that Atlus Japan communicates with "Japanese market" whereas Atlus USA communicates with the "US and related" markets, so to speak.
The problem stems from the nature of the relationship between these partners, where this is true even for many other publishers.
The balance of relationship always lean in favour of the branch that develops the game. This is not uncommon for many Japanese games, where we don't get localised trailers day-and-date. There's always some lag in the marketing and messaging compared to the Japanese information.
A lot of times, we just don't care.
But for Persona, because it's such a desired title, people are paying attention to this "disconnect."
