“Whether you’re in South Korea, Japan or America, the rules are the same: rock beats scissors, scissors beat paper, paper beats rock. All three cultures use the same fist-pumping gesture to get the players in synch, and all require the players to “throw” their symbols at the same time to avoid cheating.” “In South Korea, the game is called Kai-Bai-Bo (kai means scissors, bai is rock and bo is cloth). In Japan it’s called janken-pon, but that’s a description of the game, not a translation of the gestures. (Guu is rock, choki is scissors, and paa is paper.)” Source
