Matsudaira Norimasa served as a bushō during the Sengoku period.
In 1482, Norimasa was born as the son of Matsudaira Norimoto, the first head of the Ogyū-Matsudaira family based at Ogyū Castle in the Kamo District of Mikawa Province.
Norimasa served Matsudaira Nagachika, the second head of the Anjō-Matsudaira – the main branch of the Matsudaira clan based at Anjō Castle.
Norimasa’s daughter, Ohisa-no-kata, wed Matsudaira Hirotada, the eighth head of the Anjō-Matsudaira family.
Initially, Norimoto was based at Hosokawa Castle, but later moved to Ogyū Castle. In 1506, when Imagawa Ujichika attacked Iwatsu Castle, Norimasa served in the vanguard of Nagachika’s army.
From 1507 to 1510, Norimasa and his father, Norimoto, engaged in major renovations to Ogyū Castle.
