read genki or tae kim or whatever
start reading tadoku and the easiest possible mangas
use ocr to extract the text from those mangas and turn it into flashcards (i just copypaste everything straight into jpdb)
start playing ez games (watching jp streamers play is a decent way to get a sense of whether your comprehension is good enough for that game yet)

what also works pretty well is just yoloing a game and take screenshots whenever you dont understand something, then you can just feed those into ocr like you would with manga. also dont be too afraid to try things above your level. it'll be a slog at first but language is repetitive enough that you'll very quickly get acquainted with the most important words
