Anime is a Japanese animation. If you didn't know that, then why are you on this site?
On this site you find summaries of popular anime, as well as the trailers and places to watch or read it (depending if it comes in manga form as well). If you don't know what anime you want to watch, but have a craving for a certain genre, then go to the directory where a list of genres is kept. If you, for any particular reason, want to know more about the history of anime, then click on the History tab.
