Satoko Miyahara and Kaori Sakamoto came through practice unscathed on Thursday morning at Gangneung Ice Arena ahead of Friday's free skate.
Sakamoto looked especially sharp during the 40-minute session, tearing off jump after jump, before a crowd of a couple thousand who attended. Her run-through to "Amelie" was smooth, as it has been all season.
The 19-year-old Miyahara fell on a triple salchow while going through her program to "Madame Butterfly," but otherwise looked solid, landing several combination jumps.
