The purpose of this chapter is to identify what experiences are effective for successful foreign language learning. The authors also examined what pedagogical implications can be gained about Japanese university students’ English proficiency from their L2 narrative. While most narrative studies use narratives in L1 as research data, few studies have focused on those that learners have transmitted in L2. This study focused on narratives written in English by Japanese university students about their own English learning. By analysing the content and style of their narratives, the authors attempt to reveal what and how Japanese EFL learners actually convey in English. In the current study, 145 students at a national university in Japan wrote an essay on the theme ‘English and me’. The authors also conducted a survey to collect data on the students’ linguistic backgrounds. After a close examination of the survey and all the participants’ narratives, four samples which presented significant implications were chosen to be further analysed. This study offers a detailed analysis by focusing on content, style, and narrative structure. Throughout this chapter, the authors attempt to propose that L2 narrative is a valuable resource for the investigation of how L2 learning environment affects students’ performance.
