Japan has a 6% vaccination rate and some already arrived players have been disqualified for having The Rona.
All I can think is ... remember when the biggest concern for the Tokyo Olympics was their plans to use cardboard furniture? They are doing a 'sustainable' Olympic Village and use recycled cardboard for things, including the bedframes. 3 people on a bed could easily be over the weight limit.
I don't think it's impossible to hold safe sporting events right now, but the Olympics are huge and pull big teams from all over the planet. 11k athletes from 205 countries is a LOT more than the French Open or a Golf tourny draws. And Japan's vax rate is well below the planetary average. There is a separate vaccine supply for Olympics workers and volunteers,so hopefully they'll all be fully vaxxed in advance. Tho the wording in articles makes is sound like the shipment is still incoming and, uh, hopefully that detail is wrong. Also, Tokyo is supposed to be in a state of emergency until July 11th.
I hope it all goes well, but networks trying to trot out the usual Olympic narratives hits weird right now. I keep getting recced clips of smiling faces as people have 'miraculous comeback to nab final slot on the team!' It's going to be a strange Olympics at the very least. Making both bubbling and training work is going to be a logistical nightmare.
