A year? I spent decades “improving” my Japanese at a glacially, almost imperceptibly slow pace, then somehow stumbled across WaniKani about 1.5 years ago. Since then my progress has been shockingly fast.
In addition to WaniKani itself, the kind and knowledgeable people here have introduced me to:
All are astonishingly useful resources.
Then this thread introduced me to Tofugu’s Learn Japanese page. Which just now lead me to Tofugu’s Japanese Grammar page. [Edit: And holy cow! The podcast that was just mentioned looks amazing.]
How have I been here this long without discovering these terrific Tofugu resources?!!
