Moriwaki Hisanori served as a bushō from the Sengoku to early Edo periods.  Hisanori was a retainer of the Amago clan and served as lord of Fubeyama Castle in Izumo Province.

In 1533, Hisanori was born as the son of Moriwaki Hisasada.  Hisanori served as a chūrō, or member of the second rank of retainers serving the head of the Amago.  According to Amago family registries listing details of the retainers, along with their roles, status, and stipends, Hisanori had a fief of 28,750 koku.

In 1566, after Gassantoda Castle fell to the Mōri and the Amago clan was eliminated as a daimyō family, Hisanori served the Mōri.  From 1569, Hisanori fought on behalf of Amago Katsuhisa, the leader of the Amago revival army.  In 1570, he fought against the Mōri army at the Battle of Fubeyama.  In the ninth month of 1575, Hisanori surrendered after the fall of Kisaichi Castle in Inaba Province and, via the mediation of Sugihara Morishige (representing the Mōri), became a retainer of Kikkawa Motoharu.

Later, he went to Kyōto and, in 1616, is said to have died in the capital.  Alternatively, he may have spent his later years in the Hino District of Hōki Province.
