When I first started searching for resources to learn Japanese way back in 2012, I found TextFugu, which is still one of my favorites.
Anyways, some time after I joined TextFugu, I received an email from Koichi/Tofugu team/??? (this was ages ago, ya’ll) telling me to come check out WaniKani and a subscription discount.
So I did. And I’ve been using WK off and on since then It’s a fantastic resource if you’re a diligent self study student (which I am, but… sometimes I’m not).
