Saitō Toshichika served as a bushō during the Sengoku period.

Toshichika served as the third head of the Jizein lineage of the Saitō clan.  He was born as the eldest son of Saitō Myōjun, the second head of the Jizein family.  He was also known as Saemon, Dainagon, Gon-no-risshi, and Shinshirō.  His sisters were married to Asakura Sadakage and Kyōgoku Takakiyo.  Children included Toshinaga and a daughter.

In the ninth month of 1496, Toshichika joined his father in a campaign to subdue Rokkaku Takayori of Ōmi Province.  On 12/7 of Meiō 5 (1496), he encountered an uprising by villagers and, together with his father, was killed.  He was twenty-four years old.  His son, Toshinaga, was still an infant so he was succeeded by his younger brother, Matashirō.
