Amano Takayoshi served as a bushō during the Sengoku period. Takayoshi served as a retainer of the Ōuchi clan. He was a kokujin, or provincial landowner, in Aki Province and the second son of Amano Motosada. His older brother, Amano Takashige, served as a senior retainer of the Mōri clan.
The Aki-Amano clan were members of the Kudō clan under the Fujiwara-Nanke – a branch of the Fujiwara family. The family moved to Aki and became a landowner. Takayoshi’s lineage came from the Kinmeizan-Amano clan that began with Amano Masasada. The lineage of another Amano family who were kokujin in Aki, including Amano Okitsugu, Amano Okisada, and Amano Motosada, was the Ogiyama-Amano clan.
Takayoshi was born in 1511 as the second of Amano Motosada, a kokujin, based at Kinmeizan Castle in Aki. In his youth, Takayoshi served as an attendant for Ōuchi Yoshitaka, a powerful daimyō in control of Suō and Nagato provinces.
In 1551, a senior retainer of the Ōuchi named Sue Takafusa (later known as Sue Harukata) rebelled against Yoshitaka, resulting in the Tainei Temple Incident. As one of his attendants, Takayoshi sought to protect Yoshitaka by fleeing from Yamaguchi. However, the Tainei Temple in Nagato was surrounded by the Sue army. On 9/1 of 1551, Takayoshi joined others (including Reizei Takatoyo, Kurokawa Takakata, Okabe Takakage, Ōta Takamichi, Okaya Takahide, Negi Miginobu, and Obata Yoshizane) to fight valiantly against the Sue forces in an effort to save time for Yoshitaka to kill himself. Takayoshi was killed during this battle, dying at the age of forty-one.
Takayoshi had only one daughter and no sons. Later, out of recognition for Takayoshi’s loyalty and act of martyrdom, Mōri Motonari ordered that Amano Motosuke (the third son of Amano Takashige and older brother of Takayoshi) be adopted as a son-in-law, whereupon Motosuke became head of the Amano clan with a fief of 60 koku in the village of Ōuchi in the Yoshiki District of Suō Province.
