Shō Ienaga

Shō Ienaga, known as Tarō, was a late-Heian and early-Kamakura warrior and fifth head of the Kodama band's main house in Musashi, succeeding his father Iehiro. In 1175 he led the Kodama party in a clash over the Takayama manor.

At the Battle of Ichinotani in 1184 he killed Taira no Tomoaki and captured the Taira commander Taira no Shigehira, but his eldest son Yoriie fell. Rewarded with the jitō post of Kusanagi manor in Bitchū, he built Sarukake Castle there and founded the Bitchū Shō line.
