Hatakeyama Masahisa served as a bushō and daimyō during the Sengoku and Azuchi-Momoyama periods. He was the military governor of Kii Province (and nominal sovereign of the province).
In 1534, Masahisa was born as the second son of Hatakeyama Masakuni, a sengoku daimyō of Kawachi, Kii, and Etchū provinces and the head of the Hatakeyama-Bishū family.
Together with his younger brother, Hatakeyama Akitaka, Masahisa supported his older brother, Hatakeyama Takamasa, the military governor of Kawachi Province. Masahisa ruled the Hatakeyama territory in Kii as a district-level military governor. After Takamasa was ousted from his position by the deputy military governor, Yusa Nobunori, Masahisa met him in the harbor town of Sakai to attempt a counterattack, but was defeated and retreated to Kii. Masahisa then became the nominal sovereign of Kii with the backing of the Saika Group who lost their support from the Hongan Temple after the Ishiyama War. In 1585, he surrendered after the launch of the Conquest of Kishū by Toyotomi Hideyoshi.
Masahisa died in 1588. His son, Hatakeyama Sadamasa, was adopted by Akitaka and succeeded to the headship of the Hatakeyama-Bishū family. In the Edo period, Sadamasa’s son, Hatakeyama Masanobu, became a hatamoto, or direct retainer of the bakufu, with a fief of 300 koku. Masanobu’s son, Hatakeyama Motokuro, served in an important role for Tokugawa Tsunayoshi, the fifth shōgun of the Edo bakufu, responsible for communicating orders from the shōgun to senior officials in the administration. Motokuro received an increase to his fief which totaled 5,000 koku. After being assigned responsibility for conducting ceremonies held by the bakufu, Motokuro’s descendants served in a similar capacity.
