Indeed, it only teaches kanji but it’s invaluable to me.
Before wanikani I studied japanese for about a year and I got very mad because I had as much trouble remembering new vocab after a year of study than in the very beginning.
In my mind, the more I would learn, the easier it should get, but it didn’t.
When i tried out wanikani everything became so much better ! Instead of just remembering whole blocks of lines, their reading and their definition, I have a much keener eye and I’m developing a way to make good mnemonics.
Before, for instance, I had so much trouble differentiating 遠い from 速い ! My clue was the little drop on the lower right part of the kanji, and when I found the drop I forgot if the one with the drop was far or fast ? Ghaaaaa ! Now it’s just so easy the zombie goes far away on his scooter while on my scooter I have to deliver this bundle fast ! (how could I mix up a zombie and a bundle ! what a fool ! ^^)
Before I had to remember this whole package of lines 美術館 was a museum with a reading which was very weird to me. Now i look at it and see ‘beauty-art-public building’, that’s a museum : びじゅつかん.
Plus, when I encounter a new word, I can partially guess its meaning and reading (just as I expected after studying japanese for a year)
Yes, Wanikani doesn’t teach vocab that isn’t kanji, that’s why I add them on my SRS when I encounter them along with the vocab that I encounter which is made from kanji that I already know or kanji which aren’t taught by wanikani.
I still have a long way to go, but I’m very glad that I found this path.
