Kimotsuki Kanemori served as a bushō during the Sengoku and Azuchi-Momoyama periods. Kanemori was a member of an illegitimate branch of the Kimotsuki clan and served as the lord of Kajiki Castle in Ōsumi Province. Kanemori served as a chief retainer for Shimazu Takahisa and Shimazu Yoshihisa.
To respond to the resistance by the main branch of the Kimotsuki against the Shimazu, Kanemori joined his father, Kimotsuki Kanehiro, and supported Shimazu Takahisa. In 1554, he participated in an assault on Iwatsurugi Castle, killing four individuals. In 1555, he attacked the Gamō clan and led members of the Nagahama group of Kajiki to advance to Yamada in Chōsa held by the Kedōin clan who backed the Gamō. After the loss of commanding generals Tokunaga Yoichizaemon and Yasuda Moku-no-jō (among a total of twenty-three soldiers), the remaining enemy forces abandoned Chōsa and Yamada castles and fled to their main base at Kedōin. In view of the expansion of influence by the Kedōin clan to the area of Aira, containing them to their homeland represented a significant achievement for which Takahisa awarded Kanemori landholdings in Nishibeppu and Arikawa.
In 1559, he exchanged alliance documents with the Shimazu clan.
In 1566, Kanemori attacked the Itō clan at Mitsuyama Castle. In 1567, he made contributions in battle at Hishikari. In 1568, Kanemori was one of four individuals who received recognition from Shimazu Tadayoshi for their service in battle. The next year, Kanemori, along with Niiro Tadamoto, attacked and toppled Ōkuchi Castle for which Kanemori received from Shimazu Yoshihisa a letter of commendation and landholdings in the Soo District of Ōsumi.
Thereafter, in an effort to unify Ōsumi, Kanemori participated in numerous battles against the main branch of the Kimotsuki, the Ichiji, and the Nejime in addition to, in 1576, an assault against Takahara Castle in Hyūga Province. In 1578, he died at the age of forty-six.
