That's right, I've studied Japanese little if at all this semester. It's not that I don't have the time, but when it comes to the most important things to memorize - the vocabulary, the hiragana and katakana - I generally have prior working knowledge. (Not to say I'm perfect, though. I missed some words on the quiz today, so I might have to re-evaluate my opinion of myself.)
What I really need to work on are the little things that can only come with repeated practice and experience - namely, correct particle usage and fluency. I hope that I'll eventually master this in class. Really, that's my only option, unless someone is willing to frequently meet and converse with me in casual Japanese.
That said, I have some secret study methods that served me well in high school, and are probably still useful here at UVA. I'll share them now for the first time!
The first strategy is to adopt a mantra to motivate your studies. I have two. The first is this: "Anyone who ever told me I couldn't learn Japanese was a narrow-minded idiot." I feel that studying in defiance of someone or something always brings about the best results. My second mantra is the "Pokemon rule," which goes like this: If I could remember the names and powers of 151 Pokemon when I was a kid, then I should definitely be able to remember 23 hiragana, or 100 kanji, or whatever. (The longer you played Pokemon, the more valid this rule is. So I herd u liek Mudkips...?)
Anyway, my second strategy is to watch subtitled Japanese-language anime, and try to read signs or pick out words I know from the dialogue. It keeps me focused, it feels like practical application, and it dovetails with something I already enjoy. The only trouble with this method is that not every anime character speaks the way a normal Japanese person would! *shock* But seriously, don't let that discourage you.
My third strategy is to keep a constant stream of Japanese music flowing through my ears. This not only serves as a window into Japanese culture (you'll inevitably have to consult Japanese sources to find the popular bands), but is another way to get used to hearing the language. Again, I try to pick out words I know and understand as much of the song as possible. If I'm no good at that, I can at least enjoy the music.
Also, I'd recommend checking out the "Mainichi Shimbun" link that I've posted somewhere. The Mainichi, as it's lovingly known as, is one of Japan's top newspapers and is provided online and translated by MSN. Reading it every now and then will give you an understanding of current events and trends in Japan - which might come in handy for a future project.
And those, my friends, are my secret strategies.
