Manga are comics or graphic novels originating from Japan. Not only do manga reveal and reinforce cultural values, beliefs, and norms, particularly in Japan, but they can also be used as a teaching tool and source of information. Manga and other comics can be used in medicine to learn and teach about illness and to build empathy. They also have the power to shape public understanding of mental health issues, even nonsuicidal self-injury (NSSI).

In this episode, Dr. Yukari Seko explains how self-injury and the characters who engage in the behavior are portrayed in Japanese manga. She also discusses the importance of manga within Japanese culture. Below is a reference (with a link) to her research paper along with a breakdown of common genres of manga and, based on her study, just how many characters within each genre engage in self-injury and self-harm:
