Amano Okisada served as a bushō during the Sengoku period.  Okisada served as a retainer of the Ōuchi and Amago clans.  The Aki-Amano clan were members of the Kudō clan under the Fujiwara-Nanke – a branch of the Fujiwara family.  The clan moved to Aki Province and evolved into a kokujin, or provincial landowner. Okisada’s lineage came from the Fukino-Amano clan that began with Amano Akiyoshi.  Other kokujin from Aki including Amano Takashige, Amano Takayoshi, and Amano Motoaki came from the lineage of the Kinmeizan-Amano clan.

In 1475, Okisada was born as the son of Amano Okitsugu.  Similar to his father, Okisada received one of the characters in his name from Ōuchi Yoshioki, the sengoku daimyō based in neighboring Suō Province.

The Amano clan were indigenous landowners with the status of kokujin in Aki.  The Amano were formerly at the same level of status as the Mōri and Shishido clans.  For generations, the Amano served under the command of the Ōuchi of Suō, but, after Amago Tsunehisa of Izumo extended the influence of his clan into Aki, the Amano abandoned the Ōuchi in favor of the Amago.  Once Yoshioki gained more power, the Amano were attacked by Ōuchi forces, which drive them to the brink of being vanquished.  However, through the devices of Mōri Motonari, in 1525, the Amano were permitted to surrender and, thereafter, lived through a new era of relationships with the Ōuchi and the Mōri.

In 1540, at the Battle of Yoshida-Kōriyama, Okisada led reinforcements in support of the Mōri.  His troops succeeded in repelling Amago Haruhisa who had rode into Aki at the head of a large army.  In 1541, Okisada joined the Mōri in an attack against Takeda Nobuzane at Satō-Kanayama Castle who was aligned with the Amago.  He died of illness later that year.  His son, Amano Takatsuna, succeeded him.
