This study is the survey on the usage and the influence factors of 78 words of Japanese?style Chinese words remaining in Korean language, targeting Korean people in their 50s and 60s. As a result, 77% of men use the Japanese?style Chinese words, and 53% of elementary graduates use them. Also, people in their 50s and 60s know most of them: the awareness of men is 91%, and that of elementary graduates is 75%. However, most people in their 50s and 60s do not recognize these words as Japanese even use them without reluctance. Thus, it can be seen that gender and academic background influence the usage and the recognition of Japanese?style Chinese words. And, the words recognized as Japanese are ‘가봉’, ‘급사’, ‘십장’, ‘정종’ etc. Also, the reluctant words are ‘가료’ and ‘견양’.
