Nobutsugu was the youngest brother of Oda Nobuhide and was present for the First Battle of Azukizaka in 1542. He served his nephew Nobunaga and held Moriyama castle in Owari province after his elder brother's, Nobumitsu's, death in 1555. In 1555, while hunting, Nobutsugu accidently shot to death Nobunaga's brother Hidetaka. Fearing retribution for the accident, Nobutsugu fled Owari. He returned when Nobunaga invited him back and nothing more came of the matter. He was killed in 1574 in the fighting with the Nagashima ikko.
