Kimotsuki Kanehiro served as a bushō during the Sengoku period. He was a retainer of the Shimazu clan and served as the lord of Kajiki Castle in Ōsumi Province.
In 1558, Kanehiro was born as the lineal heir of Kimotsuki Kanemori of an illegitimate branch of the Kimotsuki clan. Kanehiro was known for being skilled in the sport known as inuōmono by which archers riding on horses would shoot at dogs running around an enclosed area. On 3/16 of Tenshō 3 (1575), he is said to have shot four dogs and, on on the following day, five dogs. On 4/21, he further served as an archer.
