Kamata Masatora served as a bushō during the Azuchi-Momoyama period. He was a retainer of the Shimazu clan of Satsuma Province.
Masatora was born as the lineal heir of Kamata Masachika. In 1585, he was ordered to serve Kinowaki Sukemasa, the lord of the manor residing at Hana-no-yama Castle in Higo. On the evening of 8/10, while en route to the castle, Masatora heard that Kai Chikahide led a contingent of 8,000 soldiers to surround the castle. Masatora hurriedly went to strike at the enemy soldiers and then enter the castle. Together with Sukemasa, he attempted to mount a defense from the west entrance. After incurring injuries, however, the effort failed and he was killed in action. He was twenty-three years old.
Owing to this battle, the castle fell and its lord, Sukemasa, and Fukami Settsu-no-suke (the lineal heir of Fukami Nagatomo, a chief retainer of the Sagara) who came to his assistance, along with more than thirty others, were all killed.
