Akao Kiyofuyu served as a bushō during the Sengoku and Azuchi-Momoyama periods. He was a retainer of the Azai and Miyabe clans in northern Ōmi Province. Kiyofuyu was the eldest son and heir of Akao Kiyotsuna. He had the childhood name of Torachiyo.
Based in Akao Castle, the Akao clan was a multi-generational retainer of the Kyōgoku clan, the shugo daimyō of Ōmi Province. After the decline of the Kyōgoku, the Akao served the Azai clan.
In 1561, while serving under Azai Nagamasa, Kiyofuyu participated in an attack against Futo-o Castle which was aligned with Rokkaku Yoshikata, the shugo daimyō of southern Ōmi. In 1573, Kiyotsuna was compelled to commit seppuku at the Siege of Odani Castle against Oda Nobunaga. Owing to the previous efforts and loyalty demonstrated by Kiyotsuna, Nobunaga personally spared the life of Kiyofuyu.
Following the demise of the Azai clan, Kiyofuyu served Miyabe Keijun and became the chamberlain of Moroiso Castle in Inaba Province. After the retirement of Keijun, Kiyofuyu served his son, Miyabe Nagafusa.
