"Chuugaku Eigo o Mou Ichido Hitotsu Hitotsu Wakariyasuku. Revised Edition" (Understanding Middle School English Again, One Step at a Time. Revised Edition) Nobuhiko Yamada Gakken Price: ¥2,750 I only skimmed through it once, so it's practically new. Of course, there are no markings. The included CD is also unopened. I am also selling other reference books, so if you would like to purchase them together, please leave a comment.
