This is quite a violence sport that is played in Japanese schools during sports day.
There is a total of 150 players with 75 attackers and 75 defenders.
While the defenders are trying to keep the pole upright, the attackers tried to lower the pole.
A victory is achieved when the pole is lowered to thirty degrees to the ground.
It is very common for injuries to happen during the game where we can see lots of people climbing and pushing one another.
