Hiraoka Fusazane served as a bushō during the Sengoku and Azuchi-Momoyama periods. He was a retainer of the Kōno clan. His common name was Michifusa Nyūdō Sakon. He received the title of Governor of Yamato. Fusazane was the lord of Ebara Castle in the Ukena District of Iyo Province in Shikoku.
Details concerning the origins of the Hiraoka clan are uncertain, however, from their base in the Ukena District, the clan appears to have gradually expanded their influence from the latter half of the fifteenth century. Moreover, Fusazane had his daughters wed Ōno Toshinao of Ōyoke Castle in Kuma (the father of Ōno Naomasa and Ōnon Naoyuki) and to Murakami Kagechika. He also arranged for political marriages with the Debuchi and Tsutsukitani in an effort to strengthen alliances with neighboring powers. Prior to Fusazane, a blood relative of the Hiraoka clan married Murakami Yoshitada (the father of Murakami Takeyoshi).
Around the time that Fusazane became a retainer of the Kōno clan, the clan was on the decline owing to, among other reasons, abandonment by retainers and invasions by the Ōtomo clan. Fusazane, however, was a brave and intelligent bushō who continued to remain loyal to the Kōno during their sunset years to the end. Along with Murakami Michiyasu, Fusazane was active in the military and political spheres. In 1554, during a revolt by Wada Michioki (the lord of Iwagara Castle), Fusazane deceived him through bargaining and toppled Iwagara with a small force. Fusazane also performed a key role on behalf of the forces from Iyo in a battle against Utsunomiya Toyotsuna during the Deployment of the Mōri to Iyo.
