And you might also find that learning a language is interesting in of itself as I did. Everything surrounding language learning is pretty damn interesting I feel, you get a much wider perspective on a lot of things that you didn't have earlier.
Just a few examples.
An insight into Japanese social culture and such, a completely new understanding of translation/localization, appreciating or hating the difference between languages, and so on.
