Fujiyori was the son of Ômori Ujiyori and was an important retainer in Sagami province for the Ogigayatsu-Uesugi. His father died in 1494 and afterwards Hôjô Sôun of Ise province made friendly representations and won the young Fujiyori's trust. In 1495 Sôun proposed a joint-hunting expedition and used this as a cover to begin moving his army into Sagami. The Ômori were caught by surprise and Odawara fell easily to the Hôjô. Fujiyori is usually described as being murdered in the process but some sources state that he fled to his Okazaki castle and afterwards became a Hôjô vassal.
