Kagatsume Masanao served as a bushō during the Azuchi-Momoyama period.  He was a retainer of the Tokugawa clan and the sixth head of the Kagatsume-Uesugi family.  Masanao served as the lord of Takasaka residence in Musashi Province.

In 1562, Masanao was born as the son of Kagatsume Masatoyo, a retainer of the Imagawa clan of Suruga Province and a descendant of the Ōgigayatsu-Uesugi family.

In the fifth month of 1560, at the Battle of Okehazama, Imagawa Yoshimoto, a sengoku daimyō and the eleventh head of the Imagawa clan, was killed.  Thereafter, the Imagawa gradually lost the ability to withstand pressure from surrounding lords.  From within the clan, a series of defections among retainers such as the Matsudaira clan of Mikawa Province as well as by family members resulted in a rapid loss of power.  In 1568, the Invasion of Suruga by Takeda Shingen of neighboring Kai Province led to the ouster of Yoshimoto’s eldest son and successor, Imagawa Ujizane, from Suruga.  Around the time that Ujizane fled to Kakegawa Castle in Tōtōmi Province defended by a retainer named Asahina Yasutomo, the various powers in Tōtōmi also began to abandon the Imagawa family.  Teh Kagatsume clan which had landholdings in Tōtōmi came under the command of the Tokugawa clan in Mikawa and Masanao’s father, Masatoyo, made contributions in an assault against Kakegawa Castle where his former lord, Ujizane, was holed-up.

From an early age, Masanao served Tokugawa Ieyasu.  In 1584, at the Battle of Komaki-Nagakute, he contributed by killing an enemy soldier.  Thereafter, he served on behalf of the Toyotomi administration in the Subjugation of Kyūshū, the Conquest of Odawara, and the Oushū Retribution.  For his service as an attendant, he received a stipend of 3,000 koku in the Hiki District of Musashi Province and the Kōza District of Sagami Province.

In 1596, Masanao died after being crushed under the gate to Fushimi Castle which was destroyed in the Keichō Fushimi Earthquake.
