Information
One Piece Water Battle is an interactive show centered around the use of water guns. In each show, Monkey D. Luffy and his companions face different enemies and invite the audience to help them by spraying the enemies with their water guns. Actors on stage often wield water guns of their own or use water blasts effects that soak the audience.

Water Battle shows were initially held once a day in the One Piece Area (ワンピース・エリア) of Universal Studios Japan and are centered around the use of water guns. Their frequency was increased to four shows per day following the initial popularity. Most shows are 20-25 minutes long.
