Akao Izu-no-kami served as a bushō during the Azuchi-Momoyama and early Edo periods. He was a retainer of Kyōgoku Takatsugu.
In 1559, Izu-no-kami was born as the third son of Akao Kiyotsuna. His childhood name was Torachiyo.
In 1573, Kiyotsuna was forced to commit seppuku while under siege by Oda Nobunaga at Odani Castle. Owing to the previous efforts and loyalty of Kiyotsuna, Nobunaga personally spared the life of Torachiyo, whereupon he became an student of acupuncture. Later, after slaying someone, he hid in the Akao territory and then served under Kyōgoku Takatsugu of Ōmi Province, adopting the name of Akao Izu-no-kami.
In 1600, he was assigned along with Kuroda Iyo-no-kami to protect Ōtsu Castle while Takatsugu was away. After Takatsugu returned, Izu-no-kami, together with Yamada Ōi, fought valiantly during the Siege of Ōtsu Castle so the Western Army could not easily take the castle by force. Although Takatsugu subsequently surrendered the castle, owing to the defeat of the Western Army at the Battle of Sekigahara, it was a meaningless victory for the army besieging the castle. Thereafter, in 1601, Takatsugu was assigned a new fief in the Onyū District of Wakasa Province where Izu-no-kami led construction of the foundations for the stone walls for Obama Castle located between the Kita and Minami rivers near Obama Bay.
