There is little translated material in Japanese-language elementary school textbooks, but what there is has many problems, not only in terms of vocabulary but also in expression. The teaching material in the Japanese school textbooks titled "Otegami," a translated version of Arnold Lobel's short story "The Letter," is no exception. Because of the peculiar characteristics of each language, the translated version has expressions that are unnatural for the Japanese language. To overcome these difficulties, this paper suggests rewriting the text of this material.
