Yotsuya Otsuka New 1st Grade Entrance Preparation Course Kanji Training This is a set of books, each with 1-48 pages packed with content. It's a set of 5 books from September to January, but 3 of them (November, December, and January issues) are unused. The September issue is completely used. The October issue has been used up to page 12. Consider these as extras. If you don't need them, I won't include them, so please let me know after purchase. As expected from a long-established company specializing in junior high school entrance exams, the questions include vocabulary and readings that are often mistaken even for elementary school-level kanji. I've provided an example in the photos, but you don't usually use words like "星雲 (seiun - nebula)," do you? Even if children know the kanji themselves, they might not know the word, so the problems are designed to catch them out. I think this sets it apart from other commercially available workbooks. Please purchase only if you are satisfied with the condition of the product.
