hiragana origin	川

spelling kana	つるかめのツ (Tsurukame no "tsu")

つ, in hiragana, or ツ in katakana, is one of the Japanese kana, each of which represents one mora. Both are phonemically /tu͍/ although for phonological reasons, the actual pronunciation is [t͡su͍].

The sokuon, which are used mainly to indicate consonant gemination, are identical but somewhat smaller.

The dakuten forms づ, ヅ, pronounced the same as the dakuten forms of the su kana in most dialects (see yotsugana), are uncommon. They are primarily used for indicating a voiced consonant in the middle of a compound word (see rendaku), and they can never begin a word.

In the Ainu language, it can be written with a handakuten (which can be entered into a computer as either one character (ツ゚) or two combined characters (ツ゜)) to represent the sound [tu͍], which is interchangeable with the katakana ト゚.

The katakana form has become popular as an emoticon in the Western world due to its resemblance to a smiling face.^[1] The small kana っ/ッ is also commonly used at the end of lines of dialogue in fictional works as a symbol for a glottal stop.
