Ok, that's strange, cause you can order from overseas through the global FC and also e.g. through HMV online Japan.
I just directly preordered both CD only editions on HMV Japan with my overseas adress without problems.
Here's her site there on the english page:

I've already bought my re(LIVE) special edition there without any problems.
Even shipping to Germany was fast.
But you know, that usually means there's going to be a collabo or a featuring on the albums avex doesn't want to pay the global rights for, just like for re(CORD), rofl.
