Correct me if I'm wrong, but isn't that a bag of MSG (Monosodium Glutamate)?
Then again, I suppose that could be salt or sugar as well, but please don’t tell me there are anime mascots for food additives now too?
I guess that’s not too far from reality, considering it’s Japan. In any case, thanks again to Winnie for sending this in!
EDIT: Thanks to anon for letting me know this is a personification of Hakata Salt (which is apparently from Mexico and packaged in Japan)!
