Akamatsu Sadanori
Akamatsu Sadanori (1306–c. 1374) was a commander and shugo daimyō of the late Kamakura and Nanbokuchō eras, the second son of Akamatsu Norimura. In 1333 he joined his father's campaign against the Kamakura shogunate, fighting at Funasaka Pass and Mount Maya.
He fought for Ashikaga Takauji at Hakone-Takenoshita in 1335 and later organized the Akahata ikki for the Northern Court. In 1349 he built Himeyama Castle, the nucleus of later Himeji Castle. He held Mimasaka as shugo from 1356 until the bakufu replaced him in 1364.
