Who will present their homework first? Janken. However, Japanese rock paper scissors, known as janken (じゃん拳) or janken pon (じゃん拳ぽん), takes on a whole new level of meaning and importance in daily life.Ĭhildren are taught janken from the youngest of ages and not only do they play it for fun, it is the means of settling all manner of disputes, disagreements, debates and pending decisions. You may view ‘Rock Paper Scissors' as just another children's game that, like other hand gesture games or ditties, passes the time and keeps them amused for a while.
