This book was banned in the elementary and junior highs schools of Matsue City for gruesome imagery. There is a call to remove it from the schools of Izumisano City due to claims that the book discriminates against the mentally ill and poor. Some say it is being challenged out of shame because of the brutal aspects of Japan’s history depicted in the book, but this has never been an official reason.
This title was not specifically threatened with a ban, but a vote was held to ban the Bone series from all elementary schools in a district of Minnesota for references in the graphic novels to gambling, smoking, and drinking. The vote to ban was not successful.
