Yotsuya Otsuka Pre-Study Series Standard Applied Exercise Problem Collection: Japanese Language, Set of 5th Grade Volumes (Upper and Lower) There are some markings here and there as shown in the images. The answer sheets for the lower volume are unused, but the upper volume has been used, with about 6 sets cut out. The name was written, so it has been cut off. #YotsuyaOtsuka #PreStudySeries #AppliedExerciseProblemCollection #JapaneseLanguage #5thGrade #JuniorHighSchoolEntranceExam #WasedaAcademy #No塾 (No cram school)
