Japanese ice dancers, who were given an opportunity to meet the ISU technical minimums through video submission, have opted not to do so.
The Vancouver 2010 men's singles bronze medallist, who switched to ice dance at the start of 2020, and partner Muramoto Kana have declined their selection by the Japan Skating Federation to be the country's reserve entry in the event behind Komatsubara Misato and Tim Koleto.
Takahashi and Muramoto were given the opportunity to meet the qualifying technical minimum score by video submission as the pandemic has limited their competition opportunities.
However, a JSF news release noted the team had withdrawn from consideration due to "poor condition".
Instead, Fukase Rikako and Cho Eichu Oliver will serve as the backup to Komatsubara and Koleto.
Takahashi and Muramoto said in a joint statement:
“We have withdrawn as stand-by for the world championships.
"The ISU awarded us an opportunity online to (score) points that would have given us a chance but as we are not fully fit, we have decided to pass this time.
"Looking ahead to the new season, we plan to take it step by step and approach our next competition to the best of our ability.
"Thank you for all your support."
