There are several versions regarding the origins of Takenori. According to one account, he was the second son of Kasuya Tadayasu, a samurai who served the Bessho clan in Harima Province. In 1577, when Toyotomi Hideyoshi launched his campaign in Harima, on the advice of his close retainer Kuroda Yoshitaka, also known as Kanbei, he took Takenori into his service as a page. In this position, the young warrior participated in the siege of Miki Castle, which lasted from 1578 to 1580 and was aimed at suppressing the rebellion led by Bessho Nagaharu.
In 1583, during the Battle of Shizugatake, Takenori served as one of Hideyoshi’s bodyguards. When the fighting reached its decisive moment, Toyotomi ordered his guards to charge into battle. Those who displayed the greatest bravery were honored with the prestigious title of the “Seven Spears of Shizugatake” (“Shizugatake no Shichihon Yari”). Among the distinguished warriors was Kasuya Takenori himself. For his valor, his stipend was increased to 3,000 koku of rice.
During the Komaki-Nagakute campaign of 1584, Takenori, together with the other members of the “Seven Spears,” served in an elite unit of 150 cavalrymen assigned to guard the main command post. Later, during the Kyushu campaign in 1587, he was once again called to serve in the same bodyguard detachment.
Kasuya also took part in overseas expeditions. In 1592, he fought in Korea, distinguishing himself during the siege of Jinju Castle. Upon his return to Japan, his income was significantly increased as a reward for his service.
In the famous Battle of Sekigahara in 1600, Takenori was the only one among the “Seven Spears” who did not side with Tokugawa Ieyasu. He remained loyal to the Western Army under Ishida Mitsunari and took part in the assault on Fushimi Castle.
After the defeat of the Western forces and the rise of Tokugawa rule, Kasuya’s lands were confiscated. However, some time later, Takenori was pardoned and accepted into Tokugawa’s service, receiving an annual stipend of 500 koku of rice as recognition for his loyalty and past achievements.
