Have you learned all the Japanese you know from watching anime? or in just reading manga?

My brain doesn't seem to do well with learning other languages. After countless hours of watching anime, I swear the only words I know are baka and kawaii...

90% Anime & rest = audio books + internet :D

anime is a good way to learn certain phrases and stuff but then you gotta be careful with words mostly used by certain genders (which i just use male words because i'm used to it and it's not like you can't use em') with manga i don't learn much from that... and besides those two, i just study it through work books and audio stuff~

Anime was a fantastic stepping stone for me. I started watching subtitled stuff from around age 11 or so because I had an aunt who was really into it. It got my ear adjusted, and helped me understand some semblance of the culture so that I was primed to learn more once I was completely immersed. After having only about eight months of study on the fundamentals in college, I found myself in Japan as an exchange student at age 18, and that's where the real learning began. I've done nothing but self-study since then, and now I work as a translator / interpreter, so make of that what you will. I will say that my progress in terms of reading and writing was extremely slow; mostly because I did not like studying Kanji (still don't). My speaking ability improved rapidly almost as soon as I went to Japan for the first time, but I largely ignored writing. I had to learn gradually over a very long, extended period of time in that regard. For a more serious student, they could probably absorb in four or five months what took me nearly six years to learn because of never really putting my nose to the grindstone. There are a lot better tools out there now for learning Kanji than what I had, though.

Practically all of the Japanese that I know, I learned by watching anime, but I have also learned some phrases by listening to Japanese music and then looking up the lyrics and the translation.

I did until I read Visual Novels and Light Novels in Japanese. Those help a lot but god help you if you need to draw every kanji to understand what's happening.
