The next year, his elder brother, Nobukatsu, became an adopted member of the Kitabatake clan, and ruled a much larger area of southern Ise Province.

Nobutaka then joined Hashiba Hideyoshi who had turned back from his own campaign, and they fought the Akechi forces at the Battle of Yamazaki.

[1] Nobutaka and his brother Oda Nobukatsu then quarreled over Nobunaga's succession at a council held in Kiyosu Castle.

[2] Nobutaka was sent to Daimidoji at Noma, Chita county, in Owari Province where Minamoto no Yoshitomo had been assassinated at the end of the Heian period.

His waka composed before dying was as follows: It is a vengeful poem that would be translated as, You had killed the one you had served / may the gods strike you down, Hashiba Hideyoshi.
