In recent years, as the smooth articulation of educational stages have been emphasized, kindergartens are required to strengthen their connection with primary schools. Some investigations suggest that although the importance of the articulation is recognized, the ambiguity of the idea makes the degree of implementation at kindergartens insufficient. While the elimination of the Grade 1 problem is in urgent need, the progress of "the articulation of learning" is relatively lagging. Some parents want early education and many kindergartens seem to have failed to explain the intention and sustainable effects of their childcare. In this paper, I compare the content of the Course of study for Kindergarten with the HighScope preschool Curriculum and point out that its goal setting lacks concreteness, making the consistency of learning between kindergartens and primary schools difficult to understand. HighScope curriculum align its contents according to the subjects of elementary and secondary education, but the idea itself has little discord with Japanese value since it considers the free play of children to be important. In conclusion, it is effective for the Japanese curriculum to appropriately incorporate the elements of the subjects centered curriculum without being bound by the experience centered curriculum.
