Nagayori served Oda Nobunaga, at first in the role of page. He was primarily involved in administrative matters, but was with Oda Nobutada following Nobunaga's death at the Honnoji in June 1582. He was killed fighting Akechi troops at Nijô in Kyoto. Nagayori's father had been one of the 'seven spears' of Azukizaka (1542).
