In order to get this thing you'll have to use an auction service like www.rinkya.com. I've used them before and they are reliable but it's not cheap - tons o fees.
But hell, for someone who has everything and money no object, this might do the trick.
If you need a japanese to english translator, try www.worldlingo.com.
