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 Romaji. Also, the pronunciation is affected, transforming into /go/.
