Kojima Yatarō

Kojima Yatarō (小島 弥太郎, 1522 – 1582) was a Japanese samurai of the Sengoku period, who served the Uesugi clan of Echigo Province. He was one of Uesugi Kenshin's leading generals. His ferocity in combat gave rise to his nickname, Devil Kojima (鬼小島 Oni Kojima).

He was also sometimes called "The Ogre" because he had an image of a grinning oni on his helmet. His weapon was a kanabō, adding further to his reputation as an oni.
