Various related documents from each period were closely examined and evaluated. In addition, interviews were conducted with people who were acquainted with her activities.Results: Kogouchi's career showed that she had a fortunate career as a children's librarian. Her activities were conducted based on this position which then influenced the movement of library services to children. Her most distinguished contributions were: (1) the approach toconducting systematic activities and creating a network system, and (2) the approach to establishing children's librarianship as a field and developing specialists in that field.
