This research aims to report on the implementation of extensive reading classes at a university and to gain suggestions for class improvement by analyzing the changes in the learners from their work. The subjects of this research were three intermediate Japanese language learners. Throughout the classes, the learners were instructed to document their observations, and during the final class, they engaged in book reviews and reflected on their overall learning experiences. An examination of the learners' work revealed that as the classes progressed, the learners demonstrated an increased focus on vocabulary acquisition. It is recommended to provide opportunities in the future for both the teacher and the learners to consider the distinctions between extensive reading and reading comprehension.
