Not gonna lie, this is badass. Here is what wikipedia has to say:
Bo-taoshi (Japanese: 棒倒し, “pole bring-down”), is a capture-the-flag-like game, played on sports days at schools in Japan. Two teams of 150 individuals each vie for control of a single large pole. Each team is split into two groups of 75 attackers and 75 defenders. The defenders begin in a defensive orientation respective to their own pole, while the attackers assume position some measure away from the other team’s pole. A team is victorious if it is able to lower the pole of the opposing team (which begins perpendicular to the ground) to a thirty-degree angle (respective to the ground), before the other team reaches this goal.
