A 2 han chiitoitsu tsumo is not possible, as chiitoitsu is always closed, so it also scores [[mentsumo]]. Like all hands, once you reach 5 han or more, fu is no longer relevant for scoring. | A 2 han chiitoitsu tsumo is not possible, as chiitoitsu is always closed, so it also scores [[mentsumo]].

High scoring chiitoitsu hands are possible even without dora. The highest possible [[riichi]], [[ippatsu]], [[menzenchin tsumohou|tsumo]], [[haitei raoyue and houtei raoyui|haitei]] and [[chinitsu]]. With the 2 han for chiitoitsu, the combination brings the hand to a whopping 12 han. Note that [[tanyao]] cannot be added, as the hand 22334455667788 can be scored as [[ryanpeikou]] for an additional 1 han. In some [[rule variations#Daisharin|rule variations]], this hand is an [[optional yaku|optional yakuman]], known as "daisharin", "daichikurin", or "daisuurin", depending on the suit. | High scoring chiitoitsu hands are possible even without dora.
