The Janken Ritual: Step-by-Step Guide

Step 1: 最初はグー (Saisho wa Guu) – “Starting with Rock”

Before any gestures fly, players synchronize by saying “最初はグー” (saisho wa guu) while showing closed fists. This phrase literally means “first is rock” and ensures everyone starts simultaneously.

Example dialogue:

• Japanese: 最初はグー！
• Romaji: Saisho wa guu!
• English: Starting with rock!

Step 2: じゃんけんぽん (Janken Pon) – The Big Reveal

Immediately after the opening, players chant “じゃんけんぽん” (janken pon). The magic happens on “ぽん” (pon)—this is when everyone reveals their chosen gesture.

Sample conversation:

• Japanese: じゃんけんぽん！
• Romaji: Janken pon!
• English: Rock paper scissors!

Step 3: あいこでしょ (Aiko Desho) – Handling Ties

When players throw identical gestures, it’s called あいこ (aiko)—a tie. Players then say “あいこでしょ” (aiko desho) meaning “it’s a tie, right?” and immediately play another round.

Tie scenario:

• Japanese: あいこでしょ！
• Romaji: Aiko desho!
• English: It’s a tie, let’s go again!

Cultural Significance: Why Japanese People Love Janken

Rock paper scissors in Japanese serves multiple social functions beyond simple entertainment. In Japanese society, where harmony and fairness are paramount, janken provides an impartial way to make decisions without anyone losing face.

Common uses include:

• Determining batting order in sports
• Choosing who pays for dinner
• Selecting group representatives
• Breaking classroom ties
• Office decision-making

This democratic approach reflects Japanese values of collective decision-making and avoiding direct confrontation—concepts you’ll encounter frequently when learning about Japanese culture, much like understanding Japanese greetings in social contexts.

Advanced Janken Variations

あっち向いてホイ (Acchi Muite Hoi)

After winning janken, the victor points in a direction while saying “あっち向いてホイ” (acchi muite hoi). If the loser looks in the same direction, they lose completely. If they look elsewhere, they play janken again.

Team Janken

With multiple participants, the game continues until only one gesture type remains. This variation can involve dozens of people and creates exciting tournament-style competitions.
