There is something bizarre about a sporting event designed to bring people and nations together but from which spectators have been excluded. Most foreigners are currently forbidden from setting foot inside Japan, let alone inside the Olympic stadium. In many senses, Tokyo 2020 — which like the Uefa Euros retains its original name, despite a year’s delay — encompasses the worst of our pandemic-ridden world: the global elite can attend while the rest of us have to settle for watching it on TV.
