The purpose of this paper is to analyze the changing structure of education of school teachers for sixty years in Japan.
After the WW II, teacher education system was changed to "open system", where any graduates of any kind of colleges and schools can get teacher licenses. However, national colleges of education supplied many new teachers in compulsory schools.
During several waves of teacher shortage and surplus, national colleges of education experienced restructuring. However, teacher demands are growing, they are in process of expanding capacities. Also, private colleges of education are newly established and expanding their programs and student capacities. In near future, they will recruit more than half of the new teachers. We will see new structure of teacher education system; national colleges of education,private colleges of education and liberal arts colleges with teacher education programs.
