The Blu Ray edition of Final Fantasy VII: Advent Children hit Japanese shelves earlier this week, and the first day sales numbers are in.  The high def extended version of the movie sold around 100,000 copies in it's first day.  The version of the movie that came packaged with Final Fantasy XIII demo was the best seller of all the available bundles, selling 70,000 copies.  The overwhelming sales of the Final Fantasy XIII bundle would seem to indicate that the demo was a driving factor behind the package, especially considering that the game was marked up an extra 1,000 yen.

Overall, pretty impressive numbers for the movie.  Last year in Japan, the best selling anime/video game related Blu Ray only sold about 30K units in it's first day.

Final Fantasy XIII is an RPG developed by Square Enix.  The highly anticipated title is due out later in 2009 in Japan, though a Western release has not been announced yet.
