The founder of our university, Mikio Mizuta, was born in 1905 in Awa County, Chiba Prefecture. After graduating from Awa Junior High School, and then Mito High School, he proceeded to the Faculty of Law of Kyoto University. During his years as a student, he participated in anti-war and anti-military movements, being a young man with a burning passion for the creation of a new society. In 1946, he was elected for the first time to the first House of Representatives after the war. He is highly esteemed for his over 30 year commitment to the development and growth of the Japanese economy. He served several terms as a Minister of International Trade and Industry and Minister of Finance.

On the other hand, he was also an enthusiastic educator since the days he had worked as an elementary school teacher when he was young. His stance was that "to build this country, we must raise talented and skilled young men with an excellent character". Hence his support for compulsory education and educational facilities paid for by the National Treasury, as well as for government aid for private schools. And in April 1965, he founded Josai University, realizing the dreams he had on education.
