'''Daburu riichi''' {{kana|両立直}} or {{kana|ダブルリーチ}}, is simply '''double riichi'''.  It is a special case for [[riichi]] on the first turn. Specifically, if the player reaches [[tenpai]] before their first discard (i.e., within the first 14 tiles), and before anyone has made a [[Naki|tile call]], then riichi turns into double riichi. Double riichi is worth 2 han instead of the usual 1 han.

Double riichi is not mandatory, but rarely do players decline an opportunity for it. In addition to the added han, a double riichi hand is much faster than the average hand.

Double riichi is not possible when anyone makes a tile call before you, even if you have tenpai on the first turn. A player's own [[kan]] will deny this yaku. In [[sanma]], [[kita]] calls will also deny this yaku.
