Anime Details

There are 70 episodes of the Cardcaptor Sakura (カードキャプターさくら) anime, which began screening in Japan on the 7th of April 1998 and concluded with the final episode on the 3rd of March 2000. It is safe to say there will never be any more episodes produced.

There are also two cinema-release movies for the series. The first, simply titled "Cardcaptor Sakura: The Movie" (カードキャプターさくら 劇場版) played in Japanese theatres in late August and early September, 1999.
