So, you wanna learn the Nipponese, huh? Well, you've come to the right thread. You know the drill; All of the relevant resources are available below. It's not an official list or anything, just an OP I threw together from items taken from previous threads. If you have any suggestions on how this list can be improved, then please don't hesitate to say something.
Learn the Kana. Start with Hiragana and then move on to Katakana. Yes, you need both, and yes stroke order is important. Use Realkana or Kana Invaders for spaced repetition. Alternatively, you can use the Anki deck, but I'd recommend the first two. Tae Kim has a Kana diagram on his website, and you can use KanjiVG for pretty much any character.
You have to learn vocabulary and grammar in order to speak and understand the language. Some will tell you to grind the Core2k/6k deck until you're blue in the face, others will tell you that grammar is more important. Truth is, you need both, but it doesn't really matter which one you decide to do first. You're teaching yourself here, so you move at your own pace and do what you're most receptive to. If you want grammar first, then Tae Kim has a great introductory grammar guide, there are numerous grammar related videos in user's all-in-one-Anki-package, IMABI has an active forums and an abundance of information on grammar, and there's always YouTube if you're lazy. On the other hand, if you want to learn vocab first, then grab the Core2k/6k and grind until you're blue in the face. For mnemonics, see Kanji Damage.
That's what these threads are for aside from the obligatory shitposting. You shouldn't assume that anyone here knows more than you, but there are anons here who are willing to help. Try to find shit out on your own, for fuck's sake, but if you're stumped, then maybe someone will have something to say that can point you in the right direction.
