If you guys are interested in that game you can get it at numerous online dealers.
Here's one. NCSX is VERY reliable. I've ordered from the NUMEROUS times...
Here's another site. Play Asia is also a great site.
I
HIGHLY recommend the game. It's a bit hard to navigate without any knowledge of japanese, however. The main menu is in English, but to get into everything in depth it's a bit of a pain...
It's on backorder last time I checked though...
