By analyzing the literature and document, this paper explores the new curriculum guideline for primary education in Japan. It consists of (a)a thorough understanding of the revising processes of the curriculum guideline and of the importance of curriculum reform; (b)a comparative study of the contents of the old curriculum guideline and the new curriculum guideline; (c)a suggestion for curriculum reform in Taiwan's primary education. The revision of the curriculum guideline has been heavily based on the curriculum evaluation by MEXT, which obeys the "principle of surviving," i.e. to train student's capacity of surviving in present times. According to this principle, all subjects of study like Japanese, social studies, arithmetic, science as well as physical education are designed. The final part of this paper suggests that we should learn from Japan's curriculum reform and take the "principle of surviving" to reform our own education system, including national curriculum evaluation, curriculum reform, the enforcement of the capacity of surviving, the reviving of discipline and moral education.
