Sō Morinao

Sō Morinao was a warrior of the Northern and Southern Courts period and the eldest son of Sō Morikuni. Born in Chikuzen, he lost a struggle for the family headship to Tsuneshige, Morikuni's designated heir.

While Tsuneshige joined the Northern Court, Morinao served Kikuchi Takemitsu on the Southern Court's side. He fought the forces of Imagawa Ryōshun, the shogunate's commissioner in Kyushu, and was killed in battle in 1372.
