Riichi Mahjong Yaku List

A yaku is a scoring pattern — the recognized hand shapes and situations that make a win legal. Riichi mahjong has one iron rule: a winning hand must contain at least one yaku. Dora tiles add han but never satisfy the requirement on their own, which is why a hand full of bonus tiles can still be unplayable.

Below are the 37 standard yaku with their han values, the twelve yakuman included. Han is shown for a concealed hand; where open melds change the value, it says so. Each entry gives the Japanese name in kanji, since most clients and tables show them that way. If a term is unfamiliar, the fundamentals are in the riichi mahjong rules guide.

One-han yaku

The daily bread of the game. Most winning hands stack two or three of these together with dora.

Two-han yaku

Stronger patterns that often anchor a hand on their own. The han column shows the concealed value.

Yakuman

The ceiling of the game: twelve patterns worth a fixed 32,000 points on a non-dealer ron before any other count. Most rules double some of them for perfect forms, and a few tables add regional ones such as nagashi mangan or renhou.

How han and fu turn into points

Every win is priced in two units. Han is the headline: one for each yaku, plus one per dora. Fu is the fine print — a small count (usually 20 to 70) reflecting shape and circumstances: triplets weigh more than runs, and certain waits or a self-draw win add a little. Base points are fu multiplied by two raised to the power of two plus han; from five han upward the formula hits the cap and the hand jumps to fixed prize tiers.

One worked example: a 30-fu, 4-han hand is 30 × 2⁶ = 1,920 base points, which rounds up to 2,000 — exactly mangan, 8,000 points on a non-dealer ron. Won by the dealer the same hand pays 12,000, and taken by self-draw it splits as 2,000 from each non-dealer plus 4,000 from the dealer.

The table gives the tiers. Dealer wins pay 1.5 times the listed ron value; on a self-draw the payment splits across all three opponents with the dealer paying double. Riichi sticks and honba bonuses sit on top and vary by table.

Which yaku should beginners aim for?

Tanyao is the workhorse: a hand of nothing but 2s through 8s assembles itself, survives open calls at most tables, and stacks freely with riichi, pinfu and dora.

Yakuhai is the open-hand answer: a single triplet of dragons or a favorable wind makes any hand legal, and you can pon your way there.

Riichi turns almost any concealed tenpai into a winning hand — when in doubt on a concealed hand, the answer is usually riichi.

And the trap to avoid: hoarding honors and terminals builds hands with no yaku at all. If your hand drifts that way, commit to chanta or junchan early, or bail out to a safe tanyao shape.

Frequently Asked Questions

Have another question? Let us know.

How many yaku are in riichi mahjong?

Thirty-seven are in standard use and all are listed above — eleven worth one han, ten worth two, four worth three or more, and twelve yakuman. Regional and optional patterns exist beyond these, but the thirty-seven cover virtually every hand you will ever see.

Can you win without a yaku?

No. A complete four-sets-and-a-pair hand with no scoring pattern is not a legal win, and dora tiles never substitute for a yaku — they only add han to a hand that already has one. The one widespread exception is nagashi mangan, a house rule paying mangan for a hand of terminals and honors safely discarded through an entire drawn hand.

What is the easiest yaku for beginners?

Tanyao — all simple tiles, no terminals or honors — and yakuhai — a triplet of dragons or favorable winds. Both can be completed with open calls, and either combines freely with riichi and dora for a cheap but respectable hand.

Learn them at the table

Reading the list is step one; watching a yakuhai pon arrive at the right moment is step two. Our table enforces every yaku and settles the points automatically.

Play Riichi Mahjong

Han values follow the standard Japanese rules used by most online clients. Individual tables may adjust specific patterns — most commonly open tanyao, red fives and local yakuman — and their settings always win.
