Since it was first published in 1984, the focus of this series has always been to teach Japanese for effective communication. Japanese for Busy People III: The Workbook for the Revised 4th Edition focuses on speaking, listening, reading, and writing, with longer passages to challenge mid-beginner and intermediate-level learners. The workbook supplements the exercises in the textbook to help learners better grasp the meaning of the expression introduced therein and give them practice using them in their own speech. Each unit also comes with slightly more challenging exercises intended for learners who wish to eventually proceed beyond intermediate Japanese. The workbook can be used in parallel with the textbook or on its own, either in the classroom or for self-study.
