"5-6 Year Olds: Enjoyable Brain-Boosting On-Do-Ku Practice Book" Gakken Yoji Work Editorial Department / Nobumi Kato Price: ¥750 I've only glanced at it, so please refrain from purchasing if you are overly concerned about condition. There are some minor chips on the corners. #GakkenYojiWorkEditorialDepartment #NobumiKato #Nobumi_Kato #Book #Language/Japanese"
