Well, what I’d say about kawajapa is that I appreciate the ‘no preconceptions’ approach to Japanese grammar. What I mean is that in the example of labelling the passive tense the receptive tense because she feels that better explains the grammar, I think that kind of approach can help people who don’t get the usual way of teaching the grammar even if the result is the same. I like that she keeps the videos short and to the point, and keeps telling the viewer that it’s not that complicated. I feel like that will be helpful for many people.
I completely agree about the pretension which take the form of sounding like she’s discovered the One True Approach and everyone else is wrong. Also (and what I was referring to earlier) I think in her quest to make it seem as though Japanese grammar is completely logical, she ties herself up in some logical knots. I don’t think the grammar of any language is completely logical as it’s formed by the speakers of that language, not a cabal of language planners designing it like the Manhattan system of numbered streets and avenues.
But that aside, I do appreciate her approach by and large, and pretentious or not, she’s actually quite open to debate on her website which makes the android seem more human. Also, I don’t know what’s up with the audio processing, or the whole android/doll concept for that matter, but it doesn’t bother me inordinately.
Anyway, from what I’ve seen, the grammar study she presents never gets beyond a basic level, and once you’re past about an N4 level of grammar knowledge the YouTube offerings are fewer. Nihongonomori seems like a popular one.
