Kanako's rotation slowed down after she grew, and her technique was never great to begin with, and now that's starting to show as she continually gets dinged with URs. Plus she doesn't have great spins or lines either, she doesn't point her toes, her flexibility is not exceptional, her legs are short, and some of her positions look sloppy. Even her 3t-3t, by far her strongest element, routinely gets dinged for under-rotation. Then she has the big flutz, mule kick into all her toe pick jumps, seems to struggle with 3lo and often 2-fts her 3sal. I would honestly be surprised if Kanako manages to medal, let alone win, a World or Olympic medal anytime soon because I think she'd need a major overhaul of her technique or a lot of polishing in her spins/stretch and artistry, and maybe both these things, to have a good chance, and that will take some time to carry out, if she even chooses to address these issues at all.
In my eyes, Kanako is the weakest link of the "top" Japanese ladies right now, but she's also by far the youngest, and probably the best hope for the future simply because the others aren't likely to stick around past 2014 and none of the youngsters are really exceptional as of yet. But the Japanese Fed seems to like her, at least prefer her to Akiko, so it's hard to know what will happen.
