According to the language type theory, the grammatical function of Japanese nouns is expressed by the case of nouns. The meaning of "case of a noun" indicates the meaning relationship between the lexical meaning of “case of a noun” and the other elements of the sentence. Therefore, this paper argues that a simple explanation of “case of noun” in the field of Japanese teacher education will not only help students to clearly understand the noun, but also understand the structure of auxiliary words and sentences, as well as the meaning relationship of the corresponding parts.
