The controversy surrounding the Machida match incident resulted in a knee strike during the game, but VAR did not intervene.

"Confronting the problem head-on is essential to the solution," says the JFA.   Reactions and protests on the field can influence subsequent punishments and decisions.

Violent protests may result in a yellow or red card for the players involved.   The incident sparks debate on refereeing, fairness and the importance of sports.

The effectiveness of protests depends on how players and officials handle disagreements during the match.

Others believe that calm and respectful communication can influence referees to reconsider their decisions.
