Given that I have no idea what else would be in it for Japan, I am going to say "maybe". This is a worldwide direct, and they are most certainly not going to be revealing all of the localizations for NA/EU... for Japan.
NA/EU is easy to make sense of since it has things like DQVII, DQVIII (both of which, at this point, in the west and if you didn't know any better, you'd probably think were Nintendo properties), Dragonball Fusion, EOV, and a bunch of other late localizations and coming releases like Pokemon. Might even see MHStories.
But Japan isn't going to be seeing that as it'd make zero sense.
Let's see, I can see:
- Monster Hunter Stories for Japan (not out yet)
- Pokemon Info (obviously)
- Monster Hunter GX (?)
- ...? Lightning Returns to Termina: Electric Boogaloo?
