Literally the only one with notable results at worlds and gpf except for the very very last event of that entire quadrennial where she stood beside Higuchi on the worlds PODIUM.
She didn't stand beside Higuchi. They were sandwiching Kaetlyn Osmond, who actually won the event, something no Japanese has done at worlds or gpf in the alleged "Miyahara Era".
The only major international competition she won was Four Continents...which was also won by Mai Mihara and Kaori Sakamoto.
So yes, she was the top of the mediocre crop of Japanese ladies over the last four years, but she certainly didn't "carry" the Japanese ladies like Mao Asada did. She isn't even the Fumie Suguri of her time, as she at least won a gpf in her day.
