Katsunaga was sent to Nobunaga's aunt at Iwamura castle as a young boy and when that place fell into Takeda hands in 1572, Katsunaga became a Takeda hostage. In 1581 Takeda Katsuyori repatriated Katsunaga back to the Oda and shortly afterwards he was given Inuyama castle in Owari province. He died alongside his father at the Honnôji in Kyoto in 1582.
