how do you sign up for the Fan-sama club card? Do you need a Japanese address or something? Maybe silverbolt can help answer this too.
since you need a Japanese address for almost anything,this is what tenso.com does for you. it gives you an address in Japan where you can have stuff sent to. Tenso will then inform you that something has arrived,and you can have it mailed to you (they only use ems though).
of course,you also need a credit card for the fan club fee,and paypal to pay tenso for the shipping & handling.
the only downside of tenso is that they are ONLY a package forwarding service, so they don't buy for you or bid on auctions. They do seem to be getting support from some big shops: mu-mo has tenso built in (avex's online shop) and I think rakuten also.
of course,if you have a friend in Japan who will let you use his address and who will forward it to you, that's fine too :-)
I've been using tenso for half a year now, and I'm in the fan club of Ayumi Hamasaki,Perfume & Idoling ;p
