Hola de México
Yeah, I don’t think we’ll get WaniKani in Spanish anytime soon. It’s probably not profitable, and anyway there’s always stuff like Anki, which is free, and I bet someone’s made a Kanji/Spanish deck already.
Also, parte del problema is just how different our Spanishes are. Basic things and grammar would be mostly ok, but the moment you start with colloquialisms and jerga it’s near impossible. If a Spaniard were to tell me something was la leche I wouldn’t get what’s going on with the milk. If I told you “Eres un fresa!” maybe you wouldn’t get why I was calling you a strawberry?
