In this article, the compound postposition “よね(yone)” in Japanese sentences is the subject of investigation. The results point out the following three points. (1) Compared to the direct expressions of complaint toward an opponent who made a tardy appearance such as “it will be awkward if you are late” or “don`t be late,” a confirmation requesting expression like “was it two o`clock?” using “yone” makes euphemistic sense. Therefore, it is clear that “yone” creates indirect expressions. (2) “Xyone. Y“ was observed as a popular type of sentence structure among the practical examples. In this case, many speeches from “Y” have the form of request, wish or opinion asking the listener to do something. It is clear that “yone” is used to soften these demanding expressions. (3) In conclusion, “yone” not only has the function of requesting confirmation but also (1) the function of emotion expression and (2) of indirect expression. Given the fact that it expresses consideration for the listener`s knowledge as well as emotion, it is similar to the postposition “ね(ne)”.
