Tsu (kana)
Tsu (hiragana: つ, katakana: ツ) is one of the Japanese kana, each of which represents one mora. Both are phonemically /tɯ/, reflected in the Nihon-shiki and Kunrei-shiki Romanization tu, although for phonological reasons, the actual pronunciation is [t͡sɯᵝ] , reflected in the Hepburn romanization tsu.
