Question: what is ko in hiragana?
Answer: こ, in hiragana or コ in katakana, is one of the Japanese kana, each of which represents one mora. Both represent IPA: [ko]. The shape of these kana comes from the kanji 己. This character may be supplemented by a dakuten; it becomes ご in hiragana, ゴ in katakana and go in Hepburn romanization.
