Amano Takatsuna served as a bushō during the Sengoku period.  Takaktsuna was a retainer of the Ōuchi and Mōri clans.  Takatsuna was the head of the Fukino-Amano clan, a kokujin, or provincial landowner, based at Yoneyama Castle in Shiho-no-shō in the Kamo District of Aki Province.  Takatsuna was the eldest son of Amano Okisada, succeeding his father as head of the clan in 1541.

The Aki-Amano clan was a member 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 family of influence.  Takatsuna’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.

The Amano clan was a kokujin indigenous landowner in Aki originally at the same status level as the Mōri and Shishido clans.  For generations, the Amano were under the influence of the Ōuchi from Suō Province.  In the era of Takatsuna’s father, Okisada, Amago Tsunehisa of Izumo Province began to extend his influence into Aki upon which the Amano separated from the Ōuchi and affiliated with the Amago.  However, once Ōuchi Yoshioki regained his power, in 1525, he surrounded the base of the Amano at Komeyama Castle.  Just before their decimation, Mōri Motonari mediated a surrender of the Amano.  Okisada used this as an opportunity to deepen relations with Motonari by exchanging a written pledge (known as a kishōmon) not to disregard one another and, thereafter, moved beyond a subservient position vis-à-vis the Ōuchi and the Mōri.  During the Tenbun era (1532 to 1555), Takatsuna endured a hostage relationship with Ōuchi Yoshitaka and received one of the characters in his name from Yoshitaka, adopting the name of Takatsuna.  At this same time, he deepened relations with Mōri Takamoto and, in 1549, entered into an agreement with Takamoto for a relationship akin to siblings.

In 1547, Takatsuna succeeded his father, Okisada, as the head of the Amano clan.  In 1554, after the Mōri became independent of the Ōuchi, Takatsuna submitted a pledge to request affiliation with the Mōri.  In 1555, he contributed land in the Kamo District with a value of eighty kan to the Namitaki Temple to pray for safety and a long destiny, but, in the month after the Battle of Itsukushima, he died on 11/27.  Takatsuna did not have an heir so he was succeeded by his younger brother, Amano Motosada.
