From PlayAsia. This is the link. Limited time offer ($100 off).
$300 + $25 shipping to the US, This is the lowest price I've ever seen.
The game is in Japanese but it's like the monster hunter, so not knowing Japanese is not a big deal. If you have a JP PSN account, you can also try out the demo first. A pretty impressive game if you like monster hunter.
I was quoted $280 for this from AmiAmi
