"Adults Don't Know!? The Basics of Money: Why and What Quiz Picture Book" Michiko Izumi Price: ¥1300 #MichikoIzumi #Michiko_Izumi #Book #Society/Economics/Finance I bought this book about three years ago, looking for an easy-to-understand book on economics and finance. It has many illustrations and diagrams, making it a good book for children and junior high/high school students to gain basic knowledge.
