It depends...very serious ones can learn you about stuff like morality, honor, the romantic mumbo-jumbo that I love so dearly.
But you're right, watching anime in Japanese makes you learn some. It's like that with all shows you watch in another language, though. You learn certain catch phrases that you remember, certain words that are used a lot and such. Watching TV is one of the best ways to learn another language. My teachers are always telling me to watch more German and French TV, really.
