Hatakeyama Tadaaki

Hatakeyama Tadaaki (d. after 1358), first named Yoshiaki, was a warrior of the Ashikaga-related Hatakeyama clan, a son of Hatakeyama Muneyoshi. After Ashikaga Takauji's victory at Tatarahama, Tadaaki was sent to Hyūga to subdue Southern Court forces in Kyushu, bringing local lords to submission by 1339. In 1345 he was appointed shugo of Hyūga.

During the Kannō Disturbance he sided with Ashikaga Tadayoshi, but defeat at Shibushi Castle in 1357 by the Shimazu and by Kikuchi Takemitsu shattered his power; he fled to Bungo in 1358.
