Andō Takasue served as a bushō and sengoku daimyō of Dewa Province during the Sengoku period. He was the seventh and the ninth heads of the Minato branch of the Andō clan. Takasue was the maternal grandfather of Andō Chikasue. He was first known as Sadasue.
There are differing accounts regarding his place in the genealogy of the Andō clan. According to some, Takasue was the son of Andō Tomosue. As noted below, however, Takasue once transferred headship of the clan to Tomosue and entered the priesthood. After the premature death of Tomosue, he returned to secular life, reverted to the name of Takasue, and became the head of the family again, so there appear to be discrepancies in the genealogies.
Takasue protected the shrines and temples and reconciled with the main branch of the Andō known as the Shimokuni (Hiyama) Andō with whom the Minato-Andō had been in conflict from the era of Andō Akisue in the late Muromachi period. He arranged for his daughter to become the formal wife of Andō Kiyosue, a sengoku daimyō and the seventh head of the Hiyama-Andō. In 1543 and 1546, he exchanged letters with Shōnyo, the tenth high priest of the Hongan Temple of the Jōdo-Shinshū sect. In an effort to bring stability to his territory, Takasue fostered close relations with powerful families serving with the central authorities.
Takasue did not have a natural son. His younger brother, Andō Tomochika, had a son named Andō Tomosue. Takasue adopted Tomosue as a successor, but Tomosue died at an early age. He then adopted Kiyosue’s second son, Andō Harusue, changed his name to Tomosue, and welcomed him as the eighth head of the family. This was significant because Kiyosue was the head of the opposing Hiyama-Andō. Takasue entered the priesthood, adopting the monk’s name of Kōkaku or Tessen-an. Tomosue, however, died prematurely, so he returned to secular life, changed his name back to Takasue, and became the ninth head of the family.
Takasue died in 1551. He has the posthumous Buddhist name of Taikyo. After his demise, Andō Shigesue, the third son of Kiyosue and, with respect to Takasue, the grandchild from a daughter married into another family, became the tenth head of the Minato-Andō. Shigesue, however, was a puppet of his older brother, Chikasue. Shigesue’s death in 1579 was an indirect cause of the Third Minato Disturbance in 1589.
