While Kaori did well, she would have never receive the score she received at NHK internationally for that skate. People talk about underscoring in Japan and overscoring in Russia, but I would say it is just different philosophy. In Russia, even if we can admit that the sores are somehow higher than they would be on the international competition, they are, I dare to say, equally higher, from the first to last skater. In Japan, it was obvious that they separated Kaori (and they would add Rika and Satoko probably if they would have participated) from the rest.
So while Anna, Sasha, Aliona, currently Kamila and maybe some others (Daria, Sofia in the future, possibly also Liza, though she is often losing points for some reasons discussed here from time to time) should score highly over 220 as a basic limit if they won't bomb (which if of course possible) and over 230 and even 240 if clean, I would say that for Kaori the score around 225-230 internationally is possible, but it requires an exceptional skate. So, Kaori can overscore russian skaters, but it requires many things to happen.
There is of course Rika, who could be considered a thread, in fact probably the only thread that doesn't require those "many things to happen", but I need to see her to skate to judge her chances. Satoko is, I'm sorry, out of the game and the rest of the japan ladies, plus Young You, who seemed to be another big competitor as Rika, are too inconsistent and with not many reserves in their bags that would allow them to make mistakes.
