"I'm honestly relieved," Hanyu was quoted as saying by Kyodo news agency.

"I felt as though I was about to cry even before the six-minute warm-up."

Six-times national champion Hanyu said he would keep practicing the quadruple axel with the aim of landing it in competition after nailing it in training last week.

The Beijing Games run from Feb 4-20.
