 He was the second son of Kasuya Tadayasu, a retainer of the Bessho clan of Harima Province.
 He held the title of Naizen no Kami (内膳正).
 Following the Chūgoku campaign, Takenori became a page of Toyotomi Hideyoshi due to the recommendation of Kuroda Kanbei.
 Takenori achieved notoriety due to his distinguished combat at the Battle of Shizugatake, where he was known as one of the Seven Spears of Shizugatake, and for this distinction he received a stipend of 3,000 "koku" from Hideyoshi.

 The town shares its name with Harima Province, one of the old provinces of Japan.
