Riichi Mahjong Yaku
Double Riichi
Also known as: Daburu Riichi · Double Reach · ダブル立直
A Riichi declaration made on the player’s first uninterrupted turn.
Yaku value
Closed hand
2 Han
Open hand
Closed only
Requirements
Start with a closed hand already in tenpai and declare Riichi on the first discard, before any player has called a tile or declared a Kan.
Common scoring mistake
A prior call cancels the uninterrupted-first-turn condition. Double Riichi replaces ordinary Riichi rather than adding another 1 Han.
Values follow common modern Riichi rules. Local and tournament rules may differ, especially for double Yakuman.
