And I have a question about the type of payment they accept. I have an Amazon and Amazon UK account so I figured I would be able to check out with the same card I have on those two, but the only option available says Convenience ATM. Is that the card I have on account or something else?

NO! Do NOT use that option. Here in Japan the convenience stores have ATM's and that would allow you to pay ONLY from a convenience store ATM here in Japan. You'd best use your normal Master Charge, Amex or whatever.

Oh, thank goodness I asked. Thanks for the response danwiz! Anything else I should know about when dealing with Amazon JP or am I ready to go?

I've bought CDs from Amazon Japan and just used my Amazon.com login (I thought the e-mail address worked on all the sites?), and in turn used my card just fine. You don't need to use anything other than your regular credit card.

Awesome! Making my 1st purchase now. Thanks guys!

All my payment options ahve been lsited among all the worldwide Amazon sites, as long as you login with your usual .com login. They may call them something else, but they have always been listed.

Are you going to tell us what you bought? Maybe a great deal on a Japanese DVD? We might like to buy one too!
