, is a capture-the-flag-like game, played on sports days at schools in Japan. The game, traditionally played by cadets at the National Defense Academy (NDA) of Japan on its anniversary, is famous for its size, wherein two teams, totaling 150 individuals, each vie for control of the opposition's pole. Each team is split into two groups of 75 attackers and 75 defenders. The defenders begin in a defensive orientation respective to their pole, while the attackers assume position some measure away from the other team's pole. When the defending team has their pole brought lower than 30° to the horizontal (beginning perpendicular, or 90°, to the horizontal), they lose. Until a rule change in 1973, the pole had only to be brought lower than 45° to the horizontal.
