This study examined features relating to the production and perception of Japanese accents by Korean learners and the relationship between the production and perception. Japanese words with two to five morae were used as the study materials. The participants in this study were 14 Korean learners of Japanese in their 20s; moreover, they all had Seoul dialects. The results of the production experiment indicated that Korean learners tend to pronounce Japanese words in type-2 accent patterns; such learners have a narrow pitch range. Moreover, Korean learners tend to pronounce a single word with two falling pitches, which would cause a native Japanese speaker to hear two accented morae in a single word. Further, a type-0 (Heiban; flat) pattern appeared in Korean learners` pronunciation. Incidentally, type-0 does not appear in Korean pitch patterns. The average percentage of correct answers in the perception experiment was 72%. The percentage of correct answers of type-2 and type-0 were more than 85% in words with less than or equal to three morae. The results indicate that difficulty in perception can be attributed to individual accent types. Furthermore, words with type-1 (Atamadaka) and type-2 accent patterns had a high percentage of correct answers, but type-0, type-3, and type-4 patterns were difficult for the learners to produce. The results suggest that production and perception are interdependent. In the future, longitudinal studies on the acquisition of Japanese accents are required.
