same year, he fought in second Tensho Iga War against Iga inhabitants. In 1582, as Oda Nobutaka's second in command, Nagahide launched a campaign on Shikoku; but before he made any progress, Nobunaga died during an attack by Akechi Mitsuhide. Nagahide abandoned the campaign and turned back to joint Hashiba Hideyoshi avenge this by killing Mitsuhide at Battle of Yamazaki. 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.
