Welcome to TF!
I too first came into contact with Japanese as a kid studying Karate (Shotokan) and later was exposed to anime. This was particularly good for me as my Sensei spoke Japanese, so all the Japanese terms in class were spoken properly, thus I got a good feel for pronunciation early on.
I still have major problems understanding fast spoken Japanese, but at least my pronunciation is pretty good.
