Japan Olympics in 2021
Russia will not be able to compete in the Japan Olympics in 2021. Russia bans the use of the name Russia, the Russian Republic, the Russian flag, the national anthem.
The reason for this is that in 2019 the World Anti-Doping Agency will ban Russia from participating in international competitions for 4 years. This is due to a state-sponsored ban on stimulant use. Yes an athlete is not alone with a government connection.
Russia reduced the ban to two years in 2020 after referring it to a sports arbitration board. Accordingly, they will not be able to play in the Olympics under the Russian flag.
Therefore, Russia is competing under the name of the Russian Olympic Committee (ROC). They use the Olympic rings and their traditional red flag with the Olympic colors.
The national anthem cannot be played when a Russian athlete wins a gold medal. Instead, the Piano Concerto No. 1 was created by a musician named Pyotr Tchaikovsky will be played.
