Just confirmed at formula1.com.
"Formula 1 has announced that the 2021 Japanese Grand Prix has been cancelled, with race organisers citing 'ongoing complexities' related to the Covid-19 pandemic."

It's a real shame. Suzuka is such a wonderful circuit. I find it odd though that they managed to host the Olympic Games in Japan but felt it necessary to cancel the Grand Prix.
