Under the influence of Uchimura, Dr. Matsumae held study group meetings (Bible and Education Study Group) at his home with several like-minded colleagues. They discussed their views on life and the world, as well as their sense of mission and ideals, and Dr. Matsumae ultimately decided to devote the rest of his life to education. In January 1935, after returning from study abroad in Germany in June 1934, the Institute of Electrical Engineers of Japan awarded Dr. Matsumae the 10th Dr. Asano Prize for his research on long-distance non-loaded cable carrier communication system. Dr. Matsumae used the prize money to a home for himself along with the Dr. Asano Prize Memorial Hall (the current location of Bosei Gakujuku) in Musashino, and continued hosting study group sessions at his home. Many like-minded colleagues gathered to talk, study, and learn together, and they came to share the dream of building a university.
Private school activities became impossible in July 1944, when Dr. Matsumae, who was busy working to end the World War II as soon as possible, received a call-up notice to serve temporarily as a second-class private in the Japanese army.
The reopening of the school began with the Matsumae Youth Judo-Juku in May 1976, and in January 1982, the school became an institution affiliated with the Tokai University Educational System (TES), and it remains so to this day.
