The university was founded in 1886 (Meiji 19) as Sendai Theological Seminary by Oshikawa Masayoshi (1850–1928), one of Japan's first Protestants, and Protestant missionary William Edwin Hoy. Oshikawa, an ex-samurai in Matsuyama became the seminary's first president. In 1891, the school was renamed Tohoku Gakuin (東北學院, Tōhoku gakuin) and a course for non-Christian students was added.

The first president Oshikawa resigned in 1901 and was succeeded by David Bowman Schneder (1857–1938). In 1904, college courses were added and authorized by the Specialized School Order. The college at first had two Departments: Letters, Theology. In 1918, Normal School and the Department of Commerce were added. In 1926, the main building (still used today) was built in Tsuchitoi Campus. Schneder left the college due to age, but even in his last days he had strong faith and gave the sermon titled "I am not ashamed of the gospel" (1936, the 50th anniversary of the school).

During World War II, the college was virtually forced to stop functioning and Tohoku Gakuin College of Aeronautical Engineering (東北學院航空工業專門學校, Tōhoku gakuin kōkū kōgyō senmon gakkō) was established instead (1944–1947).

After the war, following education reforms in Japan, it was reorganized into the Tohoku Gakuin University in 1949.
