I can only say I have never seen such magnificent performances by a retiring athlete as Mao's this past season and last. She did not look like someone who should retire to me - just someone who was injured and needed to heal. But apparently her injury was a sort that skating on her level aggravated. To me she did not go out on the low note of Japanese Nationals, which I didn't see, but on the high note of those fierce and daring Amor Brujo programs and the demanding, exquisite Bach exhibition.
One thing about Japanese skaters in general, and definitely Mao, is that show skating is not trivial for them. In the US shows like SOI are often cheesy and silly. Skaters often do only one or two easier jumps in their programs. (Of course there are the Nathan Chens who go out and destroy themselves but he will learn.) But Japanese skaters treat show audiences with enormous respect and skate their best for them. For that reason I think there is much more of Mao's skating to come. Hopefully with Lori's continued collaboration, she can have a John Curry-like post-competitive career... some of it in the USA, I hope!
Thank you, Mao!
