Yamana Okitoyo served as a daimyō during the Sengoku period.  He was the military governor of Tajima and Bingo provinces.

In 1468, Okitoyo was born as the third son of Yamana Masatoyo, a bushō, shugo daimyō, and the military governor of Yamashiro, Aki, Tajima, and Bingo provinces.  Masatoyo was the successor to Yamana Sōzen, the commander-in-chief of the Western Army during the Ōnin-Bunmei War.

After his next older brother, Yamana Toshitoyo, was removed from the line of succession, Okitoyo was designated by his father to succeed him.

In 1512, however, the Kakiya clan (deputy military governors of Tajima) led a revolt by an influential group of kokujin, or provincial landowners, comprised of the Kakiya, the Tainoshō, the Yagi, and the Ōtagaki known collectively as the Four Divine Kings of the Yamana.  This group backed Okitoyo’s younger brother, Yamana Nobutoyo, enabling him to inherit the headship of the main branch of the Yamana clan and the position as the military governor of Tajima and Bingo.
