Kiyohiko Azuma
Kiyohiko Azuma (東清彦 or あずまきよひこ Azuma Kiyohiko, born May 27, 1968 in Takasago, Hyōgo Prefecture) is a Japanese manga author and artist.
In his manga he writes under the hiragana form of his name, which has led some non-Japanese-speakers to confuse him for a woman (as they have mistaken the masculine ending -hiko for the feminine -ko).
Notable works:
Yotsuba&! (2003-)
Azumanga Daioh (1999–2002)
Next author (Rumiko Takahashi)
