TOKYO — The Olympic flag arrived here after a 28-hour flight from Rio de Janeiro on Wednesday, as Japan prepares to show the world that its planning for the 2020 Games will be as precise as preparations for the Rio games were chaotic.
Ground already has been broken on a new Olympic Village, and site preparation is nearly complete for a new National Stadium that will host opening and closing ceremonies and major field events.
Ambitious plans call for dazzling new venues, development of the city’s under-used waterfront district and the use of futuristic technologies like hydrogen power and humanoid robotics.
