Japanese New Year Cards

I am trying to find a special New Year's card for my Japanese girlfriend. These cards are a big problem in Japan, and I want to find an authentic place to buy a made in Japan. Does anyone have good places to buy items like this?

Thank you

Try checking a bookstore like Kinokuniya Japanese. I only know of 3 places in the United States, SF, LA, San Jose and Kinokuniya bookstores. Other than specialty stores like Kinokuniya, it could be very difficult.
