My general approach is to use Anki as my primary resource with the addition of the Genki textbook, video lectures and grammar videos on YouTube (Toki ni Andy, Game Gengo, Livakivi, etc.), and immersion content (Manga, anime, YouTube). I use Anki because I believe it’s the most effective method for me having used it previously to learn Esperanto; although I believe that you should use whatever method is the most fun for you, whatever will keep you coming back for daily work is good. Don’t fall for the “Bro Science” language learning people who promise quick shortcuts, there are none, these people are usually trying to sell you something.
My daily study consists of about 40 minutes of Anki per day. I split my time between two decks, which is suboptimal in terms of occasionally containing duplicates, but I like it as it serves as a method of chunking my study out throughout the day and as a way to recognize the same Kanji in different contexts. These two decks are the KanjiTransistion and Core 2.3k decks. I do four new cards from the KanjiTransistion deck and three new cards from the 2.3k deck. Following that if I’m in the mood I’ll return to reviewing my Hiragana and Katakana decks (you should do this first if you haven’t already!). I also use the Review Heatmap plugin to see my streak, which helps me stay focused on goals and milestones.
You should form your own opinion about what method of learning works best for you, but don’t fall victim to spending time strategizing and figuring out the scientifically perfect way to learn the language, there isn’t one. If you’re spending time planning how you’re going to learn the language, you’re spending less time actually learning. The only way to get good at a language is to literally be exposed to it and learning it for 1000+ hours.
