Ryūzōji Kaneie served as a bushi during the Sengoku period. Kaneie was the father of Ryūzōji Takanobu.
In 1540, Kanie was born as the son of Ryūzōji Iesumi of the Mizugae-Ryūzōji, an illegitimate branch of the Ryūzōji clan.
Kaneie was adopted by his uncle, Ryūzōji Iekado, who is surmised to have been the next head of the Mizugae-Ryūzōji family. In 1545, Kaneie’s father and adoptive father (Iesumi and Iekado), his younger brothers (Sumiie, Yorisumi), his younger brother-in-law (Ieyasu), and many other family members were purged.
Kaneie, along with Iesumi, is said to have been killed by Baba Yorichika. According to one theory, Kaneie and his father were defeated in battle and fled. Later, while heading to their lords (the Shōni clan) to seek vindication, they were murdered.
