If you got an android phone (not sure if this exists for iPhone, but try searching for it on the appstore as well) you can download the application called Human Japanese lite. It's a REALLY good and well made application for learning japanese and i really recommend everyone that can to get it. It goes in deeply with all the pronounciations first, then goes to writing and so on.
I've browsed through it and loved it, but since i'm not actively learning Japanese atm (busy with school) i haven't gotten acquainted with it more than that.

Anyway, Human Japanese Lite, go get it!
