I'm looking for a safe website to buy all of series one with out having to buy all the packs and find them.

You can try purchasing them from Amazon or eBay -- look for keywords like "Animal Crossing Cards Complete". They would usually cost around $150+, just ensure that it comes from a trusted seller.

Also can you use Japanese cards in an American game. Thanks.

Yes, all of the Amiibo and Amiibo Cards are region free.
