The purpose of this paper is to consider the issue of implementing value education in Japan. To that end, images, actual conditions of use, and similar issues related to the keyword of children's "values" was investigated. Although a somewhat common image was also attained, it was shown that variations are large and the familiarity with the word itself, "value", is sparse. Next, books and other teaching materials including the word "value" were classified. It was found that there are few materials containing contents related to value that could be carried over from elementary school to junior high school, and that fragmentation increased in accordance with grade level. Given the foregoing, we studied the gap between the sense of values that children have acquired, and the value connotation included in books and other teaching materials related to morality, as a means to identify issues related to the assimilation of moral education in Japan.
