But according to Japanese financial newspaper The Nikkei , the organizers estimate it will cost an extra 2.7 billion U.S. dollars, including costs for venue rentals, rebooking hotels and additional payments for staff and security guards, among others. Those costs could still come down depending on the outcome of negotiations.

　　The Olympics have never faced this much disruption in peacetime, and the decision to delay the event has created unprecedented challenges, Tokyo 2020 president Yoshiro Mori said.

　　Tokyo 2020 staff "will experience difficulties they have never experienced before. I am sure they will rise to the occasion. This is going to be a very difficult task that we are facing," he said.

　　No deadlines have yet been set for the rescheduling of the Games, which are now due to take place by summer 2021, but Mori said he would ensure "all the decisions are made as quickly as possible."

　　Muto underscored the scale of the task ahead, saying even he "didn't imagine at all we would be tested to this degree."

　　"We want to make sure we go beyond this test and that next year in Tokyo, the torch is lit for the Olympic and Paralympic Games. We believe this is the mission we face."

　　土耳其运动员感染，国际奥委会受指责

　　在伦敦举行的奥运拳击资格赛中，两名土耳其拳击手和一名教练本月感染了新冠病毒，国际奥委会因此备受指责。

　　土耳其拳击联合会主席戈兹格茨指责道：“国际奥委会拳击工作组和伦敦承办方竟然没有考虑到疫情而推迟比赛，还像什么事情都没有发生一样，要知道从去年12月以来，全世界都处于高度戒备状态。”

　　国际奥委会对此没有正式答复。On a separate matter, The IOC has been accused of putting athletes' health in danger after two Turkish boxers and their head coach tested positive for COVID-19 after returning home from an Olympic qualification tournament in London last week.

　　The Boxing Road to Tokyo tournament, featuring competitors from across Europe, started on March 14 but was suspended after just three days.

　　Eyup Gozgec, president of the Turkish Boxing Federation, was scathing about the tournament in the British capital.

　　"The International Olympic Committee Boxing Task Force and the local committee in London, responsible for the organization, acted as if nothing happened rather than postpone the tournament over coronavirus while every corner of the world has been on fire since December," he said.

　　Gozgec, who is also vice-president of the European Boxing Confederation (EUBC), said his team went to London on March 11 to prepare for the tournament but found no protective measures in place at their hotel or elsewhere.

　　"There were no protective measures in the hotels we were staying, whether it be hygienic disinfectants, gloves or a warning sign," he said. "All the coaches and athletes ate in self-service style from the same kitchen. There was neither a warning nor any other measure as if the virus had not visited there."

　　An IOC spokesperson was quoted as saying by the Guardian: "For understandable reasons we will wait to receive the details from those concerned before making an informed comment.”
