Different anon here, I am going to do the same. Currently trying to teach myself as much as I can, but I'd rather take a class.
I've always had a fascination with Japanese culture, but I didn't decide to start learning the language until I really wanted to read untranslated mango/eroge. And yes, I realize that makes me a huge fucking weeaboo, but I hide my powerlevel well. Everyone who sees me studying Japanese believes that it is simply a step in my quest to learn the three big asian languages (I'm asian, so that's perfectly acceptable).
