Pacific Mall is a waste of time when it comes to anime and manga in my experience, although you can still find some places selling plushies and things like that, and there's three or four food stores with fun snacks. You used to be able to find all sorts of stuff there, but now I think there's maybe one store left selling anime, and everything else is just life-action drama DVDs and music videos or whatever, with the odd Ghibli film here and here, but never anything obscure, since law enforcement cracked down on all the illegal subs a couple years ago and all those shops got replaced by phone stores.
But if you have better luck or do manage to get to J-Town, definitely let me know.
