Ochi Ienori served as a bushō during the Sengoku period. He held the title of Inspector of the Board of Censors.
Ienori was born as the son of Ochi Ienori (written with a different character in his name) of the Ochi clan, a kokujin, or provincial landowner, in Yamato Province. His childhood name was Harutake.
In 1507, he succeeded his father, Ienori, as head of the family after this father died during an invasion of Yamato by Akazawa Tomotsune. That same year, Hosokawa Masamoto (the deputy shōgun of the Muromachi bakufu) was assassinated in an event known as the Eishō Disturbance while Tomotsune was killed in battle in Tango Province.
However, the following year, Ashikaga Yoshitane (the former and eighth shōgun of the Muromachi bakufu) marched upon Kyōto backed by Ōuchi Yoshioki, the sengoku daimyō of Suō and Nagato provinces in the western part of Japan. Along with these developments, the Hosokawa and Hatakeyama clans who both wielded influence in Yamato split into two factions. After the collapse of the Yamato kokujin ikki (an alliance of landowners for the purpose of protecting their interests), Ienori and Furuichi Chōin sided with the faction led by Ashikaga Yoshizumi, Hosokawa Sumimoto, and Hatakeyama Yoshihide, while Tsutsui Junken, Tōichi Tōharu and others backed the opposing faction led by Ashikaga Yoshitane, Hosokawa Takakuni, and Hatakeyama Hisanobu.
In 1516, Ienori prevailed over the Tsutsui and their followers but then died in 1517.
