What's "Pinfu"? A Simple Guide to One of the Most Common Mahjong Yaku

Hey everyone! I'm shoma, and I’ve been playing Mahjong for over 10 years.

Today, I want to talk about Pinfu (平和) — one of the most common and essential yaku (winning hand patterns) in Mahjong.
If you're just starting out, Pinfu is a must-know. It's simple, frequent, and forms the foundation of many strong hands.

Let’s dive in!

🀄 What is Pinfu?

Pinfu (pronounced "peen-fu") literally means “peace” in Japanese, and it refers to a hand that’s neatly and harmoniously constructed.

When you make a Pinfu hand and win, you get 1 han (a basic point multiplier).

To summarize:

It's called “peace” because the hand looks and feels calm and clean. (I mean... maybe. Who knows why they named it that! 😂)

🔰 3 Conditions to Make a Pinfu Hand

Let’s break down what you need:

✅ 1. All Melds Must Be Sequences (Shuntsu)

A sequence (shuntsu) is a set of three consecutive tiles in the same suit, like 1-2-3 or 4-5-6.

❌ If you have a triplet like 7-7-7 (called a koutsu), your hand can't be Pinfu. It has to be all sequences.

✅ 2. The Pair (Jantou) Can’t Be a Value Tile

Your pair (jantou) — two identical tiles — must not be a value tile.

Value tiles include:

• Dragons: White (Haku), Green (Hatsu), and Red (Chun)

• Winds: East, South, West, North — if they match your seat or the prevailing wind

✔ If your pair is a regular number tile (like 7 Dot or 2 Bamboo), you're good!

✅ 3. The Wait Must Be a Ryanmen (Two-Sided) Wait

You need a two-sided wait, like holding 5-6 and waiting for a 4 or 7.

That’s called a ryanmen wait — and it’s required for Pinfu.

❌ The following waits are NOT allowed:

Kanchan (closed wait) → e.g., 3-5 waiting on 4

Penchan (edge wait) → e.g., 1-2 waiting on 3

Tanki (single tile wait) → e.g., waiting for one tile to complete the pair (like a lone 8)

🎴 Example of a Pinfu Hand

Here’s a sample hand:

Pair: 8 Bamboo
4-5-6 Bamboo
7-8-9 Dots
7-8-9 Characters
5-6 Characters (waiting on 4 or 7 Characters → ryanmen wait!)

✔ All melds are sequences
✔ Pair is a non-value tile
✔ Waiting on a two-sided (ryanmen) wait

✅ → This is a Pinfu hand!

💡 Recap: How to Remember Pinfu

Pinfu = Sequences only + non-value pair + two-sided wait

It’s a simple yaku that shows up all the time, even in high-level games.

💡 Heads-up: If you win by ron, it’s just 1 han.
But if you win by tsumo (self-draw), you get Pinfu + Tsumo = 2 han. That’s a great value hand!

✨ Final Thoughts: Pinfu Is the Foundation of Mahjong

Once you understand Pinfu, building efficient hands becomes way easier.

It’s one of those yaku that you’ll use again and again — no matter your skill level.

Get used to spotting Pinfu shapes, and you’ll feel your game improving in no time.

That’s it for today!
