"Junior High Jiyujizai Problem Collection: English - A Super Problem Collection to Develop Jiyujizai Ability from Basic to Difficult Schools" "Junior High Jiyujizai Problem Collection: Mathematics - A Super Problem Collection to Develop Jiyujizai Ability from Basic to Difficult Schools" "Junior High Jiyujizai Problem Collection: Japanese - A Super Problem Collection to Develop Jiyujizai Ability from Basic to Difficult Schools" By Chugaku Kyoiku Kenkyukai (Junior High School Education Research Association) Price: ¥1500 each I believe there is no writing inside, but some problem numbers are marked with a highlighter. There are a few pages like this in each subject. Please check the photos. The back cover of the English answer key is also slightly dirty. There is some wear and tear when the covers are removed. I have inspected the books, but there may be oversights. I would appreciate your understanding. I think these books can still be used for exam preparation, etc. I would appreciate it if those who understand that these are used books would consider purchasing them. Thank you for looking. #ChugakuKyoikuKenkyukai #Books #Language/English/Mathematics/Japanese"
