ABSTRACT
From the end of World War II to 1955, curriculum studies in Japan were actively conducted by school teachers, with a focus on the areas of curriculum formation and development. Influenced by the philosophies and theories of progressive education in America, an organization for educational activism called the Koa-Karikyuramu Renmei (Association of Core Curriculum) was established in 1948 by researchers and teachers to convert the prewar curriculum based on subject matter to a new one centered on children, and an original, truly Japanese theory of core curriculum was developed and put into practice as well.
