The purpose of this study is to investigate by means of corpus-based analysis the linguistic features of spoken and written data that were produced by Japanese EFL learners. Previous SLA studies have shown that variability in interlanguage performance can be observed across different production modes (spoken/written). Little research, however, has been done to investigate interlanguage variability among Japanese secondary school students. The present study focused on different modes of production of data using the same task at the secondary school level. Oral and written essays on the same topics were collected from junior and senior high school students. The word and part-of-speech sequences (n-gram) in data from forty learners were analyzed. The word and part-of-speech trigrams of spoken and written corpus data were compared. The results reveal some differences in learners'output across different modes.
