The Soccer J-League has decided to use the official ball of the tournament from the match on the 21st of this month after the World Cup starts in November.
At the World Cup Qatar tournament, which will start in November, an Adidas ball called "Al Rifra", which means "travel" in Arabic, will be used as the official ball.
This ball uses 20 large and small panels to reduce air resistance and improve kick accuracy and stability when the ball flies.
In the J-League, we have decided to use it as an official ball from the game on the 21st of this month, which is half a year before the opening of the World Cup.
It is used in league games and J League Cup games.
