A military commander, daimyo, and court noble of the Sengoku and Azuchi-Momoyama periods. Head of the Hida Anegakoji clan (Miki-Anegakoji). His father is Yoshiyori Anegakoji (also known as Tsuguyori). Since Yoritsuna's primary wife is the daughter of Dosan Saito, he is a brother-in-law to Nobunaga Oda. In February of Eiroku 5 (1562), Yoshiyori attained the Junior Third Rank. Receiving a character from the name of the Kanpaku Sakihisa Konoe, who had mediated for them, Yoshiyori took the name Tsuguyori Anegakoji, and at the same time, Yoritsuna (then Shigetsuna) changed his name to Yoritsuna Anegakoji. In December of that year, Tsuguyori further petitioned Shogun Yoshiteru and Sakihisa for an appointment to Chunagon, but this was rejected by Emperor Ogimachi. Despite the rejection, he began styling himself as Chunagon anyway. Meanwhile, in March of Eiroku 6 (1563), Yoritsuna was appointed as a Chamberlain (Jiju), which was a formal appointment.

He suffers greatly due to his father's abnormal obsession with the title of Chunagon, which could be described as 'Chunagon sickness.'

A military commander, court noble, and daimyo of the Sengoku period. Head of the Hida Miki clan, later the Miki-Anegakoji clan. Also known as Tsuguyori. The eldest son of Naoyori Miki. In October of Eiroku 2 (1559), his eldest son Shigetsuna was recognized as a member of the Anegakoji Kokushi family. In the following year, Eiroku 3 (1560), Yoshiyori was appointed to the Junior Fourth Rank, Lower Grade, and Shigetsuna to the Junior Fifth Rank, Lower Grade and Saemon-no-suke. Furthermore, they were officially permitted to succeed to the lineage of the Furukawa-Anegakoji family. Naturally, this process was viewed as problematic by the Imperial Court, and the court was divided over whether to allow the Miki clan to succeed the Anegakoji Kokushi family (of the Ko-Ichijo branch of the Fujiwara clan). However, due to Yoshiyori's political maneuvering, it was eventually approved.

In February of Eiroku 5 (1562), Yoshiyori finally rose to the Junior Third Rank, becoming a court noble (Kugyo), and changed his name to Tsuguyori after receiving a character from the Kanpaku Sakihisa Konoe. Having gained fame unrivaled in the Hida region, Tsuguyori next sought the rank of Chunagon. This was likely because the former Hida Kokushi, Mototsuna Furukawa-Anegakoji, had held the rank of Junior Second Rank and Provisional Chunagon, and he wished to equal that status. He requested Sakihisa Konoe to petition through Shogun Yoshiteru on December 1st of the same year, but was rejected by Emperor Ogimachi on the 11th. Sakihisa tried to petition again on the 18th, but was rejected again on the 20th, and Tsuguyori's ambition failed. Nevertheless, Tsuguyori was so obsessed with the office of Chunagon that he began calling himself Chunagon without authorization.

In March of Eiroku 6 (1563), Tsuguyori was appointed as a Consultant (Sangi) and had Yoritsuna appointed as a Chamberlain, but Tsuguyori was dismissed from the Sangi post in July.
