In 1556, Narifusa was born as the second son of Arao Yoshitsugu, a retainer of the Oda clan. In 1572, his older brother, Arao Yoshihisa, was killed at the Battle of Mikata-ga-hara so Narifusa inherited the headship of the clan.
In 1575, Narifusa served in the Battle of Nagashino. Later, he served Ikeda Tsuneoki (who wed Narifusa’s older sister, Zenōin. He received Wakamori Castle and a fief of 3,000 kan. In 1584, after the death of Tsuneoki at the Battle of Komaki-Nagakute, Narifusa served his successor, Ikeda Terumasa. In 1590, after Terumasa became the lord of Yoshida Castle in Mikawa Province, Narifusa became the chamberlain of Ushikubo Castle in the Hoi District of Mikawa. In 1600, following the Battle of Sekigahara, after Terumasa became the landlord of Himeji with 520,000 koku in Harima Province, Narifusa was awarded 10,000 koku and became the chamberlain of Tatsuno Castle in the Ibo District of Harima. In 1625, he retired and transferred the headship of the clan to his lineal heir, Arao Naritoshi. For his retirement income, Narifusa received a stipend of 3,000 koku.
Narifusa died in 1630. As a maternal relative of the Ikeda clan who served as lords of the Tottori domain (comprised of Inaba and Hōki provinces), Naritoshi served as a chief retainer of the domain and as the chamberlain of Yonago Castle.
