本論文以探討日文相關科系畢業生在臺灣企業界職場能力形成過程為目的，以在臺灣的大學日文相關科系畢業5年以上，在職場上使用日文，工作資歷10年以內且無留日經驗的14名畢業生為訪談對象，透過半結構式的訪談方法調查，使用紮根理論質性分析法進行分析。其結果顯示，受訪者在職場中除了感受到自己的日語能力不足之外，也面臨著職場人際關係的困擾與專業知識不足等困難。在深切體會到職場所需與學校所學之間落差的同時，為了達成職場所要求的工作內容，受訪者多數以積極的態度去面對並設法一一解決困難，在此過程中逐漸發展出屬於自己的職場能力。此次的研究成果可以提供學校及教師在課程安排與教學內容選定時的參考。

The purpose of this study is to investigate how Japanese department graduates develop their Japanese career in the business community. The subjects of this study are related to Japanese department graduates who have graduated for more than 5 years from Taiwan's university, have less than 10 years working experiences and make good use of their Japanese ability who do not have any study experiences in Japan. We had the semi-structured interviews with 14 subjects based on 7 quest ions. According to Ground theory approach (GTA), our results show that the interviewees had faced some difficulties not only in Japanese language, but also in interpersonal relationships and lack of knowledge on the job. And they found that there is a gap between the knowledge from the school and the requirements at work, however, in order to take the responsibility and complete the assignments, they have to try to solve the difficulties proactively. Because of this developing process, they gradually have the ability to deal with different difficulties by themselves and have the confidence in the workplace. Result of this time we think that we would give much suggest to university and teachers when they improve their course of study and plan to make the syllabus.
