Mahjong Yaku List: All Hands by Han Value (1 Han to Yakuman)

Quick Answer: Japanese mahjong has roughly 40 standard yaku organized by han value — 1-han (Riichi, Tanyao, Pinfu), 2-han (Sanshoku, Ittsu, Toitoi), 3-han, 6-han (Chinitsu closed), and Yakuman (Kokushi Musou, Suuankou, Daisangen, etc.). This page lists all of them grouped by han value with conditions and scoring.

To win at mahjong, knowledge of yaku is essential. No matter how good your hand is, you cannot win without yaku. This article organizes all mahjong yaku by han value, explaining formation conditions and practical applications in detail from 1 han yaku to yakuman.

Understanding Basic Yaku Rules

What is Han Count?

Yaku have a standard called han count for scoring:

• 1 han yaku: Basic yaku (Riichi, Tanyao, etc.)
• 2 han yaku: Moderately difficult yaku (Toitoi, Chiitoitsu, etc.)
• 3+ han: High-scoring yaku (Honitsu, Chinitsu, etc.)
• Yakuman: Maximum scoring yaku (Kokushi Musou, Suuankou, etc.)
