|Unicode name||KATAKANA LETTER TU|
ツ (Hepburn romanization tsu)
- The katakana syllable ツ (tsu), whose equivalent in hiragana is つ (tsu). It is the eighteenth syllable of the gojūon order, and its position in gojūon tables is タ行ウ段 (TA-gyō, U-dan; “row TA, section U”).
Unlike the hiragana system, used for Japanese language words that kanji does not cover, the katakana syllabary is used primarily for transcription of foreign language words into Japanese and the writing of loan words (collectively gairaigo), as well as to represent onomatopoeia, technical and scientific terms, and the names of plants, animals, and minerals. Names of Japanese companies, as well as certain Japanese language words, are also sometimes written in katakana rather than the other systems.
