Tanyao
Last updated: 2026-08-18Tanyao is one of the most common 1-han yaku: the winning shape has no 1, 9, or honor tiles — only 2–8 number tiles. Study with Riichi Mahjong Yaku Guide and Counting Han.
Requirements
- Every tile in the winning hand is 2–8 in man, pin, or sou
- No terminals (1, 9) and no honors (winds, dragons)
- On this site: open tanyao is allowed (kuitan)
- Fixed 1 han
Tanyao opposes terminal/honor yaku like chanta and junchan: those require terminals in every group; tanyao avoids them entirely.
Valid example
Ron on 2 pin completes the hand. Man 234567, pin 2345, sou 678 — all 2–8 — tanyao applies.
Invalid or confusing
Contains 1 man, 9 sou, and a red dragon triplet — no tanyao. Yakuhai (red) gives 1 han, but not tanyao.
Stacking and open hands
Tanyao often stacks with Pinfu (tanpin, 2 han closed). After melding, tanyao still applies, but pinfu, iipeikou, and other closed-only yaku drop.
Sanshoku, ittsu, and others can stack; han add. Tanyao lines are a common speed route.
Scoring
Tanyao adds no special fu; fu follows melds, wait, and closed ron as usual. With pinfu, fu is usually the pinfu structure (often 30 fu). See Fu Calculation Basics.
