Ashida Nobumori served as a bushō during the Sengoku and Azuchi-Momoyama periods.  Nobumori was the lord of Ashida Castle in the northern Saku District of Shinano Province.

The Ashida clan was a dogō, or small-scale landowner, and member of the Yoda clan in Shinano.  The Ashida were originally an independent kokujin, or provincial landowner, but, in the Muromachi period, the family was divided between administrators and landowners.  The former served as councilors, magistrates, and security officials while the latter served the Ōi clan who were deputy military governors in Shinano.

In 1541, Takeda Nobutora and Suwa Yorishige invaded the Chiisagata District.  On his route home, Yorishige attacked Ashida Castle in which Nobumori (who was not even ten years old) was captured alive and forced into a subservient relationship.  In 1542, however, Yorishige was compelled by Takeda Harunobu (later known as Shingen) to kill himself.  Thereafter, Nobumori served the Kai-Takeda clan and was active as one of the retainers of the Kai-Takeda based in Shinano.

In 1561, at the Fourth Battle of Kawanakajima, Nobumori fought valiantly during an attack on Mount Saijo in Shinano.  In 1566, he served together with his son, Yoda Nobushige, at Mitake Castle in Musashi Province.  In 1568, Nobumori participated in the Battle of Sattatōge in Suruga Province.  In 1572, after Takeda Shingen attacked the Tōkai in the Western Campaign (Seijō sakusen), he served under Akiyama Nobutomo and attacked Iwamura Castle.

After the death of Shingen, Nobumori served Takeda Katsuyori and entered Futamata Castle in Tōtōmi Province.  In 1575, after Tokugawa Ieyasu prevailed at the Battle of Nagashino, Nobumori died in the castle while Futamata Castle was under siege.
