Taking into account the continued critical developments in Japan, the ISU's primary concern for the safety of all participants, spectators and members of concerned entities as well as the travel advisories from many governments to avoid travel to Japan until the situation is settled, the ISU in consultation and agreement with the Japan Skating Federation (JSF) and in line with the advise of the Japanese authorities, has concluded that the staging of the ISU World Figure Skating Championships 2011 scheduled to be held on March 21-27, 2011 is not possible and the Championships will not be held during that time.
The postponement of the Event or alternatively the final cancellation is under evaluation.
The same applies to the ISU World Team Trophy in Figure Skating scheduled to be held in Yokohama on April 14-17, 2011.
It is understood that a postponement of the above-mentioned World Championships as well as the holding of the ISU World Team Trophy is subject to the confirmation by the competent Japanese authorities that the situation is back to normal conditions allowing the safe conduct of major ISU sports Events in the Tokyo area.
As soon as the situation in this respect has been finalized, the ISU will inform all parties concerned of the decision taken.
