He served in the Battle of Anegawa 1570 against the Azai-Asakura clan, and the Hongan-ji campaign from 1570–1580.
In February 1571, Nagahide entered Sawayama Castle after Isono Kazumasa moved out, and since then he was active as a castle general with Kawajiri Hidetaka. In September 1571, after Nobunaga ordered for the Tendai Temple affiliated with Enryaku-ji at Mt. Hiei to be burned down, Nagahide and Hidetaka burned down Saimyōji temple.

When he wasn't in battle, he was aiding Nobunaga's conquests by taking care of political affairs and had responsibility for constructing Azuchi Castle, which began in 1576 and was completed in 1579. One of the characters of his family name was said to have been granted for the Hashiba name for Hideyoshi. His participation made him favored by Nobunaga, among many of other deeds. The extent of Nobunaga's trust can be seen by the fact that Nagahide married Nobunaga's niece, while his son was Niwa Nagashige. These services let Nagahide rule over the fief of Obama Domain in Wakasa Province, and Sawayama Castle in Ōmi Province.

Later, at the subsequent meeting in Kiyosu Castle where the future of the Oda clan was discussed, Nagahide supported Hideyoshi's position.
In 1583, Nagahide assisted Hideyoshi at the Battle of Shizugatake and gained Echizen Province and Kaga Province to rule, worth over 1,230,000 koku. He thus became one of the most powerful retainers and daimyō.

## Death

Nagahide died of illness in 1585. 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 a 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 Niwa Mitsushige, the family's 100,000 koku landholding was moved to Nihonmatsu, where they remained for the duration of the Edo Period.

## Azamaru sword

According to the Nobunaga Kōki, Nagahide was presented the treasured sword "Azamaru", initially held by Taira Kagekiyo. Another previous owner, Kageyama Kazukage, was blinded during the Siege of Ôgaki castle in 1547, and the next owner, Niwa Nagahide, began having eye trouble, and so the sword was believed to be cursed. Nagahide donated the sword to the Atsuta shrine, in order to be freed from the curse. After the donation, his eye troubles went away.
