Are you in Japan? I hate to break this to you, but you need to actually be located *in* Japan in order for this to work. There should be a white payment form, printed with blue ink, attached to the Table of Contents on the back page of the magazine. You would take that form, fill out your name and address, then take it to a Japanese post office or bank, where they would process the form as a type of instant money order.

And that, unfortunately, is the only way to do it.
