Baseball Ouendan
At baseball games in Japan, the outfield bleachers are used for the ouendan, which is the cheering section for each team (typically right field for the home team and left field for the visiting team). The ouendan will have trumpets, drums, giant flags, and thousands of fans chanting, singing, jumping and dancing to cheer on their team. Many fans are equipped with Kung-fu bats (mini plastic bats) that they bang together to cheer on the team. Some teams celebrate with rocket balloons or even mini-umbrellas (Yakult Swallows).
