@WillTell Shopping online might be the least of her worries. Living in a developed country in general could be difficult without any legal identification. From what I've read from the Internets, foreigner looking people in Japan, in general, would be wise to carry id papers with them if questioned by the police (though I suppose that makes things easier in great many countries). Shopping online, however, only really requires a valid credit card, by Visa preferably. A 360 years old, rich vampire could acquire such "easily" enough, I imagine. It's international, after all, and purely business. In business, money is everything. All in all, she could probably use an existing network of vampires and money to acquire a passport of some country to act as an id. I don't remember anymore how long she has been living in Japan, though, and how she pulled off the long-term residency permit. But since it's Japan and she looks like a beautiful young girl, I bet sucking the blood (non-lethally) of some lolicon pig of a high official was all that was needed to get all the permits and papers she ever wanted.
