He was also known by his court title, Dainagon (大納言). He promoted Tōdō Takatora to chief engineer. He led Hideyoshi's vanguard force a few years later into Satsuma Province, contributing heavily to his half-brother's victories in gaining control of Kyūshū. Hidenaga was awarded the provinces of Kii, Izumi and Yamato, reaching a governance of one million koku. He was regarded as Hideyoshi's brain and right-arm. He died in Kōriyama, Yamato Province (now Nara Prefecture), and his tomb is called Dainagon-zuka (大納言塚).

He took part in the 1582 Battle of Yamazaki, the Invasion of Shikoku (1585), and the 1587 Battle of Takajo, Battle of Sendaigawa and Siege of Kagoshima.[2]
