In the battle of Komaki and Nagakute, he used a 13th-century tachi of the Fukuoka Ichimonji school, to slay a samurai known as Okada Sukesaburō, therefore the blade was known as "Okada-giri Yoshifusa", now a national treasure.

Two years later in 1581, Nobunaga himself led the second invasion with an army of several ten thousand, destroyed the whole region and placing control of Iga province in Nobukatsu's hands.

When Nobukatsu and his younger brother, Nobutaka, quarreled over the matter, a council decided on the infant son of Nobutada, Oda Hidenobu.

Later in 1590, when he served at the Odawara Campaign, he refused to accept Hideyoshi's order to change his dominion, and later he not only lost his original domain but was also forced to become a monk under the supervision of some Toyotomi retainers.

After the establishment of the Tokugawa shogunate, he became the lord of the Uda-Matsuyama Domain in Yamato Province (modern-day Nara Prefecture), and comfortably lived the rest of his life.
