Uno Norikage

Uno Norikage was an early Kamakura-period Murakami Genji warrior in Harima Province. Genealogies such as the Sonpi Bunmyaku relate that his ancestor Minamoto no Suefusa was exiled to Sayo Manor, where the family settled.

During the Kenkyū era of the 1190s Norikage married a daughter of Hōjō Yoshitoki and was appointed jitō of Akamatsu village in Sayo. His heir Ienori took the village's name as his family name and became the first to call himself Akamatsu.
