Nagahiro was the ninth son of Shimazu Shigehide, lord of Satsuma Domain; Kuroda Narikiyo, lord of Fukuoka, adopted Nagahiro in 1822 later Nagahiro married Narikiyo's daughter, Sumihime. Nagahiro's mother was a woman of humble origins named Chisa; she had attracted Shigehide's attention with her "sturdy build and great love of sake." Much like his mother, Nagahiro was also well-built. He was close in age to Shimazu Nariakira, and the two had a brotherly relationship. His childhood name was Momojiro (桃次郎).
Nagahiro succeeded his adoptive father in 1834. Much like his birth father, Nagahiro was a serious proponent of technological modernization, especially with regards to his domain's military. After Commodore Perry's arrival, Nagahiro (like his close relative, Shimazu Nariakira) was a proponent of opening the country. He greatly encouraged learning amongst his retainers, and sent them to the best schools of Edo, Osaka, and Nagasaki to absorb the Western knowledge and technical expertise which was entering the country at the time. He himself also engaged in similar efforts, listening to the anatomy lectures of Philipp Franz von Siebold in 1859.
