Fūma Kotarō (風魔 小太郎) (?-1603) was the name adopted by the leader of the ninja Fūma clan (風魔一党 Fūma-ittō) during the Sengoku era of feudal Japan. According to Hojo Godaiki, the journal of the five generations of the Hojo Clan, he was seven feet tall and led a band of 200 people. It's possible that the shinobi Fuma Kotaro did not exist because there is only one historical document which describes him as a ninja.
