TOKYO — Japan has been forced to scrap plans to involve children in the Olympic torch handover and arrival ceremonies because of fears over the new coronavirus, Tokyo 2020"s chief organizer said on Friday. Organizing committee head Yoshiro Mori called it a "heartbreaking decision" to cancel a performance of 140 children at the handover ceremony in Athens. The announcement comes after organizers said they may have to scale back the torch relay and limit spectators because of concerns over spreading the deadly COVID-19. "A performance by 140 children was scheduled at the handover ceremony in Athens on the 19th (of March), but we"ll put utmost priority on the safety of children and cancel their trip," Mori told reporters. The Olympic flame is set to arrive in Japan on March 20 but about 200 children will also have to miss the welcoming ceremony in Miyagi prefecture. The torch will then embark on a nationwide relay starting in Fukushima, a disaster zone just nine years ago after an earthquake-triggered tsunami swamped a nuclear plant and sent its reactors into meltdown. Organizers have been scrambling to give assurances that the Olympics, from July 24 to August 9, remain on track despite the international outbreak of COVID-19. The International Olympic Committee insisted this week that a potential cancellation or postponement of the Games due to the virus was "not mentioned" at a meeting of their executive board. Japanese sports events from sumo to football have been cancelled or moved behind closed doors as the outbreak grows, with 97,000 infections and more than 3,300 deaths in some 85 countries. Tokyo completes permanent Olympic venues as virus fears lurk Construction of all new permanent venues for the Tokyo 2020 Olympics and Paralympics is now complete, organizers said Friday, as preparations continue despite worries over the new coronavirus outbreak. The announcement comes as the International Olympic Committee insisted this week that a potential cancelation or postponement of the Games due to the virus was "not mentioned" at a meeting of their Executive Board. The last venue, the $523-million Tokyo Aquatics Center for swimming, diving and artistic swimming, was "completed on schedule by the end of February," the organizers said in a press release. The four-story Aquatics Center will seat 15,000 fans for the Olympic and Paralympic Games. The main pool features a movable wall allowing the 50m facility to be converted into two 25m pools. The depth of the bottom can also be adjusted. Other permanent venues include the main Olympic stadium, which was designed by renowned Japanese architect Kengo Kuma. It heavily features the use of wood in a nod to traditional techniques, and is designed to counter Tokyo"s fierce summer heat. The Olympics take place from July 24-Aug. 9, but organizers have been battling to reassure athletes and would-be spectators that the Games remain on track despite the spread of COVID-19.
