Figure Skating World Championships Kaori Sakamoto and others practice officially. Sakamoto aims to become the first female skater in 56 years to win her third consecutive singles title.

Yuma Kagiyama, who is aiming for his first victory in the men's singles, practiced by playing free songs. The World Figure Skating Championships will begin on the 18th local time in Montreal, Canada.  Sakamoto was smiling as she left the venue, and her girlfriend said, ''It's okay. It was a good day for me on my second day here.''
