Janken is the Japanese version of rock, paper, scissors.  There are different types of janken all over Japan.

If you visit Japan, make sure to ask a child to teach you their local janken! Fortunately, the hand gestures, signs, and rules are the same as the English version. Rock beats scissors, scissors beats paper, and paper beats rock. In janken, rock is called 'guu', scissors are called 'choki', and paper is called 'paa'.

Face your opponent, make a fist for “rock” (guu), and say saishowaguu to begin. Chant jankenpon with your opponent and flash your hand sign on “pon.” Rock (guu) beats scissors (choki), scissors beats paper (paa), and paper beats rock.
