- fine fine fine. I get asked this question allll the freaking time and there is ONE site I found that helped me out loads back when I was in 7th grade and studying with a private teacher:
It doesn't teach the correct strokes for the hira/kata and kanji (if you really want them, I can do that for you myself) but it's enough for you to learn the former, at least. If you are really serious about it, the first step is to memorize all of the hiragana and katakana and then start to build on vocabulary. And, of course, actually taking a class, but you've said you can't do that so meh.
(If you've got the money for it, you might want to just up and buy some kind of Japanese textbook that won't half-assedly teach you what you want to know. In my honors course we use Youkoso, which is kind of hard to get used to (it's a college textbook, after all) but it teaches kanji really stinkin' well. So if you want to go with a route that's more tangible and you want your money's worth out of it, spring for a valid textbook, otherwise… you've just got to wait :P)
