Tsuuiisou 「字一色」 is a yakuman scored when the hand consists entirely of honor tiles.

Tile pattern

Agari: or

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

Agari:

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.

-For this yakuman, all [[kazehai]] (wind tiles) and [[sangenpai]] (dragon tiles) can be used.  So, that gives seven tile types to choose from.  Given the nature of [[jihai]] (honor tiles), the different types cannot be mixed to form [[mentsu|tile groups]].  Therefore, they must be collected in the form of [[Mentsu#Koutsu|koutsu]] (triplets).  This yakuman is only reasonably achievable, when in possession of at least multiple [[toitsu]] (pairs) of the honor tiles.  Otherwise, players may have to resort towards yaku, like [[yakuhai]] or [[honitsu]] for attaining [[tenpai]].

-A specific variant to tsuuiisou is possible and can be considered as a separate yakuman, '''daichiisei''' {{kana|大七星}}, which means "Big Seven Stars".  It is a variant of [[chiitoitsu]] (seven pairs). There are exactly seven types of honor tiles, which makes this difficult pattern possible but more difficult than the regular tsuuiisou.  As a consequence, this variation remains as a closed only hand.  This is [[optional yaku|optionally]] worth [[Multiple yakuman|double yakuman]].
