Sugihara Nagafusa served as a daimyō during the Azuchi-Momoyama and early Edo periods. Nagafusa was a member of the family group of Toyotomi Hideyoshi. He served as the lord of Kitsuki Castle in Bungo Province followed by Toyooka Caslte in Tajima Province. In the Edo period, he served as the first lord of the Toyooka domain.
In 1574, Nagafusa was born as the eldest son of Sugihara Ietsugu (a chief retainer of Hashiba Hideyoshi (later known as Toyotomi Hideyoshi)) in Odani in Ōmi Province. He was a younger cousin of Kōdain-in, the formal wife of Hideyoshi. His older sister was the natural mother of Kinoshita Nobutoshi and Kobayakawa Hideaki.
Nagafusa separated from his parents at a young age and was raised by Asano Nagamasa. In 1584, following the death of his natural father, Ietsugu, he is surmised to have inherited the headship of the clan, but it is not certain. Nagamasa became the lord of Sakamoto Castle which was in the custody of Ietsugu.
From 1586, Nagafusa served Hideyoshi and was awarded land in Nishidai and Shiriike in Settsu Province.
In 1589, Nagafusa was invested with the titles of Junior Fifth Rank (Lower) and Governor of Hōki. In 1592, for the Bunroku Campaign, he was stationed at Nagoya Castle in Hizen Province. On 9/2 of Bunroku 2 (1593), his fief was increased by 3,000 koku.
In 1596, he transferred from Sakamoto to the Hayami District in Bungo Province, becoming the lord of Kitsuki Castle.
In 1598, Nagafusa transferred to Toyooka Castle in Tajima Province. He served as the chamberlain of Miki Castle in Harima with a fief of 30,000 koku (20,000 koku in the Kinosaki District, 1,000 koku in the Mikumi District, 1,000 koku in the Keta District, 5,000 koku in the Oguri manor in Hitachi, and 1,000 koku in Ōmi).
After the death of Hideyoshi in the eighth month of 1598, Nagafusa received fifteen gold pieces as a keepsake.
In the first month of 1599, he waited upon Toyotomi Hideyori. In the second month, he served as a local magistrate in the Miki District of Harima.
In 1600, at the Battle of Sekigahara, Nagafusa joined the Western Army and participated in an attack against Tanabe Castle in Tango Province defended by Hosokawa Yūsai, an event known as the Siege of Tanabe Castle. Despite being on the losing side of the war, he colluded with the Eastern Army, and, perhaps based on his relationship with Asano Nagamasa, and as a younger cousin of Kōdai-in, after the war he received recognition of his rights to his landholdings.
In 1611, after the death of Nagamasa, per his will, Nagafusa was allocated 5,000 koku in the Oguri manor in Hitachi Province.
In 1614, at the Winter Campaign of the Siege of Ōsaka, Nagafusa served in a unit led by Sakai Tadayo (hatamoto under Tokugawa Hidetada). In 1615, at the Summer Campaign, he served in the same unit and took 19 heads of enemy soldiers.
In 1629, Nagafusa died at the age of fifty-six. He was succeeded by his eldest son, Sugihara Shigenaga.
