Chiihou (地和)
Blessing of Earth — a non-dealer wins on their very first draw, before any call interrupts.
How Chiihou (地和) works
Chiihou (blessing of earth) is a yakuman: a non-dealer completes their hand on their very first draw, before any call interrupts the opening turn.
A non-dealer starts with thirteen tiles; if their first draw completes the hand — with no pon, chi, or kan declared by anyone beforehand — the tsumo scores as a yakuman. Any call before that first draw breaks the pristine opening and cancels the chance, which is what separates chiihou from an ordinary fast tsumo. Like tenhou, the hand's actual shape is irrelevant: the miracle timing is the yaku. It's marginally more common than tenhou since three players are eligible each round, but still vanishingly rare.
- •Non-dealers only, on the first uninterrupted draw of the round.
- •Any call (pon, chi, kan) before that draw cancels eligibility.
- •This calculator scores chiihou hands by their patterns — count the yakuman manually if the table rules it.
Chiihou (地和) — FAQ
What's the difference between tenhou and chiihou?
Tenhou is the dealer winning on the initial deal itself; chiihou is a non-dealer winning on their first draw. Both require the opening to be untouched by calls, and both score a yakuman.
Does winning by ron on the first discard count?
Not as chiihou — that's renhou (blessing of man), a separate hand that only some rulesets recognize, often at mangan rather than yakuman value.
