This paper suggests the use of comics, or so-called manga, to support the selfdevelopment of youth. Through the usage of manga, both informational and emotional support for young people would be provided. This paper intended to create a support program that used manga for the self-development of youth. To this end, I discussed the following issues. First, through studies on the difficulties faced during a young man's self-development, I discussed the necessity of supporting the self-development of youth, and then developed an argument for supporting these youth. Second, I reviewed relevant research on self-development in recent studies related to manga, and then discussed the impact of manga on self-development. When both manga and the self are regarded as a narrative, we can regard the process of self-development as one of self-narrative development. Third, I examined the benefits and drawbacks of the use of manga in selfdevelopment, through analyses of cases, which then suggested that manga is highly suitable to supporting the self-development of youth. Finally, I suggested a selfdevelopment support program that used manga, and then described its concrete procedure.
