In this study, 96 of Japanese two word phrases learned by year 1 to year 3 students at Japanese elementary school are tested on JLPT level 3 and 4 learners. The average score of the total number of correct answers is 62.0. That is, two thirds of the 96 Chinese character phrases are correctly understood while one third is incorrectly answered. 6 of the level 3 non Japanese major students achieved the highest average of correct answers. Among the 28 level 3 Japanese major students, the majority obtained correct answers for between 11 and 20 questions, while 21 students correctly answered fewer than 10 questions. There is a great deal of individual differences in their ability to work out the meaning of the Chinese character phrases. Among 27 of the level 4 learners, more than half centered on the region of between 61 and 96.Among 210 of the level 4 learners, 18.6% scored between 11 and 20. There are only 9.0 to 10 % undergraduates who understand the Chinese characters For each of the 96 words surveyed, the rate of correct answers is calculated, and the top 15 and bottom 15 words are investigated in order to identify the shared Chinese characters. year 3s. For low level Korean learners of Japanese, it seems that Chinese characters with complex strokes cause difficulty, while the old JLPT criteria for setting exam questions do not affect the learners` level of comprehension. The current study shows the level of difficulty and unfamiliarity Korean learners of Japanese experience in learning Chinese characters. Instructors should try to develop Chinese character learning contents for Japanese leaners or incorporate various learning applications into teaching to interest and encourage learners to more actively and effectively participate in the learning process.
