This is a problem book designed to improve Japanese language skills, focusing on reading comprehension. - Title: Improve Reading Comprehension: Logical Japanese for 6th Graders - Publisher: KUMON - Content: Japanese language problem book - Target Grade Level: 6th Grade Elementary School - Price: 880 yen Thank you for viewing. There is no writing inside. The answer key is included. I erased pencil markings from dates and incorrect answers with an eraser. As shown in the photos, there is one instance of pen writing and one spot of dirt. The cover has some wrinkles. However, I believe it can still be used perfectly fine as a problem book. Please check the photos and only purchase if you are okay with the condition. Returns and complaints are not accepted after purchase.
