Andō Hirosue served as a bushō during the Sengoku period. Hirosue was the sixth head of the Shimonokuni (Hiyama) branch of the Andō clan based at Hiyama Castle in Dewa Province.
Hirosue was born as the son of Andō Tadasue, the fifth head of the Hiyama-Andō. According to one theory, he was the third son of Andō Shigesue and adopted by Tadasue. On 7/26 of Eishō 8 (1511), upon the death of Tadasue, he inherited the headship of the clan.
In 1512, Shoya and Kōji, siblings and village chiefs in the eastern portion of Ezo, led an uprising by the Ainu people during which several manor houses were attacked. This is known as the Battle of the Shoya-Kōji Siblings. Although Kakizaki Mitsuhiro and Kakizaki Yoshihiro (father and son) serving as the military governors of Kaminokuni repelled the attacks, in 1513, the rebels attacked again, toppling the Matsumae-Ōdate mansion and killing Aihara Suetane, the Matsumae military governor. Owing to the vacancy at Matsumae-Ōdate, in 1514, Mitsuhiro entered and requested Hirosue to grant him control of Kaminokuni and appoint him as the deputy to the role of Matsumae military governor. Hirosue twice refused the request, but after further requests, he finally acknowledged Mitsuhiro on the condition that a majority of the levies collected from the Kakizaki clan for marine commerce by native Japanese persons visiting the Ezo territories be given to the Hiyama-Andō clan. There is an alternative theory that the Ainu uprising was instigated by Mitsuhiro to further his own agenda.
In 1533, Hirosue permitted the ceremonial transfer of a divided tutelary deity, known as the Sannō-daigongen, to a new location. In 1546, Hirosue joined forces with Kakizaki Suehiro to suppress a rebellion launched by Moriyama Suesada at the Moriyama house in Fukaura in Tsugaru.
On 2/8 of Tenbun 16 (1547), Hirosue died and was succeeded by his son, Andō Kiyosue, who became a sengoku daimyō. During the period of Hirosue’s governance, Kiyosue wed the daughter of Minato-Andō Sadasue in an effort to promote reconciliation between the Hiyama and Minato branches of the Andō clan.
