When the issue of "bullying" first came to the forefront in schools, NHK conducted interviews and produced a special program. Back then, it wasn't called "bullying," but rather "bullying of the weak." This book was written based on numerous cases gathered during those interviews. It was published in 1984 (Showa 59). Although it's an old book, it's in good condition, without sun damage or fading, because it was kept in a cover when I bought it at the bookstore.
