The 9th son of Yonezawa lord Uesugi Narinori, he succeeded to the Nihonmatsu headship in 1868.
Nihonmatsu had just lost in the Boshin War, and as one of the conditions for its surrender to the Imperial Japanese Army, Niwa Nagakuni, the previous daimyo, retired. After the domain system was abolished, Nagahiro became a shishaku (viscount) in the new kazoku system.
