Tenhou 「天和」 is a yakuman attained by completing a hand with the 14 starting tiles that one draws during one's dealer turn. The dealer's initial hand may use any pattern, as long as 13 tiles constitute a tenpai hand, and the 14th tile counts as menzen tsumo. Tenhou does not allow a concealed Kan declaration.
Chiihou 「地和」 is a yakuman attained by completing a hand with the 13 starting tiles and the first tile that one draws during one's non-dealer turn. The initial hand may use any pattern, as long as 13 tiles constitute a tenpai hand, and the 14th tile counts as menzen tsumo.
Formation
For both tenhou and chiihou hands, no action is required from the player, other than recognition of a complete hand with the 14 dealt tiles and the declaration of a winning hand. Failure to do so may result in a lost opportunity to score this rare yakuman.
Yet, unlike tenhou, chiihou may be interrupted by tile calls prior to the tile draw; and hence the opportunity to score this yakuman. If tile calls did occur prior to the draw, then the hand is limited to a mentsumo plus any other applied yaku and/or dora.
