There is a conflicting record that Nagahide had not died of an illness, but on seeing Hideyoshi gather more power and eclipsing the Oda clan Nagahide had so long served, he felt that he had not lived up for the good of Nobunaga and the Oda clan as whole and committed suicide.

His son Niwa Nagashige later became lord of Shirakawa Castle in northern Japan, and by the time of Nagahide's grandson Mitsushige, the family's 100,000 koku landholding was moved to Nihonmatsu, where they remained for the duration of the Edo Period.
