Every time I check into this place, I'm taunted by something I see that you simply can't get anywhere else, and the fact that they won't ship to the US. There are two options as I see it to getting stuff from them. Either you travel to Japan (or if a friend's going, have him/her pick something up for you), or hire a 3rd party shipping company (I've got a link somewhere of a company that specifically orders goods from Japan for US customers). I believe the typical fee is upwards of 10-15% of the final price of the goods. Still, if there's something you absolutely have to have then it might be worth it.
Some of the really rare lefty stuff they've got right now: Gretsch Broadkaster basses, a Danelectro longhorn, a Hofner Cavern, and LEFTY FENDER JAGUAR BASSES!. Take a look:
