Seigakuin Primary School is a coeducational primary school begun by Joshi Seigakuin in 1960. Each day starts with a morning worship service. Each grade consists of 80 students and two classes. In the more than 45 years since its foundation, 3000 students have graduated from the school. Under the educational motto: "Study with all your mind, Play with all your might, and Pray with all your heart," efforts are made to educate students who "Love God and Serve His People," which is the foundational spirit of Seigakuin. This is realized through communication with Christian teachers, who play and study together with the children.
