Well you need to have some kind of reason to expose yourself to a language other then "you want to learn it". For English this has been series and movies as well.

I would get together some basic japanese dialogue due to all the subtitled animes I watch, but the writing system of japanese is just awful, it makes no sense compared to korean or chinese. Now I am stuck with being able to write some Korean words and being able to take part in a very basic conversation in Japanese, not very helpful so far, so maybe I will try some Korean Movies next.
