Tohoku Gakuin University (Tōhoku Gakuin Daigaku) is a private university in Sendai, Japan. It was founded under a Christian background (specifically the German Reformed Church, which later was known as the Reformed Church in the United States. A large part of the Reformed Church in the United States subsequently merged into what is today known as the United Church of Christ in the United States).
The university was founded in 1886 (Meiji 19) by Protestants as Sendai Theological Seminary (Sendai shin gakkō). The first president was Oshikawa Masayoshi (1850-1928), ex-samurai in Matsuyama and one of the first Protestants in Japan. In 1891, the school was renamed Tohoku Gakuin (Tōhoku gakuin) and a course for non-Christian students was added.
