For the 2016 Academic Year Shingakusha Social Studies Shin Kenkyu With Separate Volume "Commentary and Answer Key" Price: 1,180 yen This item is from 9 years ago, so there is some wear and tear, such as corner folds. I am selling it due to a move. I didn't see any writing in it, but I can't say for sure, so please purchase only if you understand. I think it can be used without any problems as a reference book. Price negotiable ◎
