Tsuuiisou 「字一色」 is a yakuman scored when the hand consists entirely of honor tiles.
Tile pattern
Development
Any wind or dragon can be used, giving seven tiles to choose from. Any non-honor tile is irrelevant for this yakuman.
Honor tiles can only be formed as triplets or pairs, so this yaku is only reasonable when in possession of many honor tile pairs (which can be ponned). Otherwise, you can go for yaku like yakuhai and honitsu.
Daichiishin
In addition to triplets, tsuuiisou can be achieved in the form of chiitoitsu. This may be considered as a separate yakuman, daichiishin 「大七星」, meaning "Big Seven Stars". There are exactly seven types of honor tile, and you cannot call pon to complete the hand, so this is much harder than regular tsuiisou. This is optionally worth double yakuman.
