Nasu no Yoichi

Nasu no Yoichi (c. 1169–c. 1189) was a warrior of the Nasu clan of Shimotsuke, famed through the war tale Heike Monogatari. He fought under Minamoto no Yoshitsune at the Battle of Yashima in 1185 and rode into the sea to shoot down the fan target on a Taira warship, earning manors in five provinces from Yoritomo.

Though the eleventh son, he succeeded after nine of his brothers joined the Taira. He is said to have pardoned and enfeoffed his brothers.
