This is a textbook for modern Japanese. It is sold as a set of 3 books. Some sections of the explanations in each textbook have been highlighted with a highlighter, but there is no writing on the questions themselves. I used them with clear book covers, so I think they are in relatively good condition, but please refrain from purchasing if you are concerned. Please note that the separate workbooks and answer keys have been detached. Immediate purchase is welcome! #ModernJapanese #EntranceExam #Textbook #DevelopmentOfModernJapaneseReadingComprehension #AccessToEntranceExamModernJapaneseBasicEdition #Tamura'sEasilyExplainedModernJapanese
