Every Japanese of a certain age has memories of the 1964 Tokyo Olympics. Emperor Naurhito, whose grandfather Emperor Hirohito opened the Games, has his own memories. He was a 4 1/2 year-old child at the time and reminisced last week with guests, including American first lady Jill Biden. “I myself have a lasting memory of the closing ceremony of the 1964 Tokyo Olympics, where athletes from different countries paraded together shoulder to shoulder, not divided by country.” the Emperor said.
