Andō Koresue served as a bushō during the late Muromachi period.  Koresue served as the third head of the Minato-Andō clan of Dewa Province.

The genealogical records of the Andō clan contain many different accounts.  In particular, with respect to the Minato family, the descendants ceased so the records are confusing.  There are many individuals with the same name as their ancestors, in addition to many name changes and the mixing together of their exploits.  The existence of primary sources of information has not been confirmed either from shrines, temples, or other locations.

Koresue solicited Andō Masasue from the main branch of the family (who had been driven out of his base in Tsugaru by the Nanbu clan) and, in 1456, had him establish a base on Shōroku Island in Akita and decimate a kokujin, or provincial landowner, named Kasai Hidekiyo.  Operating under the command of the Nanbu, Hidekiyo had governed the Kahoku area of Akita (later known as the Hiyama District).  Koresue had Masasue construct Hiyama Castle to serve as his main base.

According to records of the Nanbu clan, Masasue invaded the Nanbu territory.  In 1458, he lost to the Nanbu who took control of Minato Castle and the entire Akita District.  In 1461, he ousted the Nanbu and recovered his former territory.

Masasue endeavored to expand his power with the aim of recovering Tsugaru.  In the era of Andō Akisue, Koresue’s son and the fourth head of the Minato-Andō, this led to a power-struggle between the Hiyama-Andō and the Minato-Andō families in regard to military conscription and the Oga Peninsula.
