Hori Toshishige served as a hatamoto, or direct retainer of the shōgun, and as a daimyō during the early Edo period. Toshishige was the first head of the Tamatori domain in Hitachi Province. He was born as the third son of Hori Hideshige.
In 1599, he went to Edo to serve as a hostage of the Tokugawa clan on behalf of his relative, Hori Hideharu. He then served Tokugawa Hidetada. At the Battle of Sekigahara, he joined Hidetada’s army and attacked Ueda Castle in Shinano as defended by Sanada Masayuki. Thereafter, Toshishige was awarded a fief of 8,000 koku, but, in 1614, he was found complicit in acts that led to the removal of Ōkubo Tadachika, so he also lost his position and was sent to Okudaira Iemasa.
In 1615, at the summer Siege of Ōsaka, Toshishige contributed as a member of the forces led by Matsudaira Tadaakira, the younger brother of Iemasa. In 1622, he was officially pardoned of his crimes, awarded a fief of 10,000 koku in the Niihari District of Hitachi, and kept a residence in Tamatori, attaining the rank of daimyō. Toshishige was then ordered to support Okudaira Tadamasa, the young head of the Shimotsuke-Utsunomiya domain. In 1628, he became the head of tax collections. Thereafter, he served as the head of security for the shōgun and in successive roles as a magistrate for shrines and temples. In 1633, he received an increase to his fief of 4,000 koku in Ōmi, Awa, and Kazusa provinces.
In 1638, owing to the demotion of the Kyōgoku family of the Matsue domain in Izumo Province, he headed toward Izumo to take over Matsue Castle, but, on 4/24, died in Ōsaka on the way to his destination. He was fifty-eight years old. Toshishige was succeeded by his eldest son, Hori Toshinaga.
