Yakuwarigo is a Japanese role language defined by Kinsui (2003). Yakuwarigo is a particle, always used in the end of the sentences such as "Taberu-zo", "TO EAT : verb- ZO : particle" It is said that Yakuwarigo has gender difference by using this. For example. wa is used by females and zo and nojya used by males. Recently, learners of Japanese have greater opportunities to expand their ability through manga and anime. However, Tei (2008) has observed that the Yakuwarigo used in manga and anime emphasizes gender differences. In this study, We investigated the impression that Yakuwarigo exerts in terms of gender differences by means of a questionnaire, which was completed by Korean learners of Japanese and native Japanese speakers. I found that Yakuwarigo produces a similar effect in both groups. However, with the particle zo. which previous studies have identified as being used only by males, I found that it was believed to be used by both males and females. Further, I determined that native Japanese speakers have a different image with respect to the particle wa depending on the associated verb. These results indicate that Korean learners of Japanese have a fixed impression with respect to Yakuwarigo.
