Maybe I should try it after all...I may have it somewhere; I just have an irrational prejudice against it because it sticks fake etymologies in your head (if it's the one I'm thinking of). But who cares; it's not like I'm going into Japanese linguistics, I guess. :p I couldn't remember the kana until my second Japanese teacher taught them to us using silly drawings instead of just having us copy them (like, と is your toe from the side, with a little thorn sticking out).

(Notably, she got her master's in teaching Japanese as a second language from San Francisco State University.)
