This is a CD for learning Japanese history while listening! The main textbook has a lot of writing and cannot be sold, but the CD is unused and unopened. ⚠︎ Caution ⚠︎ This is NOT "Kanaya's Japanese History: A Book to Understand Why and How." It is only the supplementary CD. The paper is warped where the CD was cut out. I apologize for this. ※ Immediate purchase OK 〇 ※ No individual sales ✕ Thank you for looking.
