Because my Japanese skill is actually bad (which is why I'm studying it now), obviously I'd prefer a translated manga and subbed anime (not dubbed, I hate dubbed series because I want to listen to the original seiyuu's voices!). I'm not studying Japanese for manga and anime, honestly speaking. I did it because I want to know the language and be able to use it in real life chances because I wish I can go to Japan one day. Of course, manga and anime can be helpful in a way. I'm nowhere with kanji so reading raw manga in Japanese is out of question, but while listening to words, phrases, or sentences in anime and J-drama I can add bit more vocabularies or see how grammars I'm studying are put in action, even though it might not be 100% accurate to the original meaning in Japanese. That's fun in its own way. XD
