How much has WaniKani helped you in learning to speak Japanese?

As mentioned:

Also, this is taken from the FAQ and is very important to remember:

Will WaniKani teach me Japanese?

WaniKani has a very specific goal: teaching you Japanese kanji and vocabulary. These two things are often thought of as the most difficult part of learning Japanese and hold most students back. If you are comfortable with kanji and vocabulary, literally everything else gets exponentially easier.

Although WaniKani doesn’t teach EVERYTHING, it does what it does well, thus helping your other Japanese studies and providing what you need to get better.

I personally really enjoy Wanikani. It does what it’s supposed to very well: Teach kanji and vocab associated with it.

But again, as everyone else has said, more is required to become fluent.
