The purpose of this study is to investigate visual recognition of Japanese kanji-word processing on advanced-level Korean students learning Japanese. The orthographic and phonological similarities between Korean and Japanese language were treated as independent variables, while the reaction times from the visual lexical decision task were assigned as the dependent variables. From analysis, facilitation effect of phonological similarities and orthographical similarities was observed. Partly different from the result of a study by Cai, Fei, & Matsumi (2011) whose participants were advanced-level Chinese students, advanced-level Korean students in Korea have immediate processing access to concept by activating Korean phonological representation.
