This study is intended to analyze the growth process of an organization formed by women who have experienced career discontinuity and its changing relationship with the women’s reemployment support center from a social capital perspective. The results of the study are as follows. As the expectations of the organization and the meaning of learning changed, the organization evolved from a study club to an unincorporated organization and cooperative. The selfish behavior, low participation, and limitations of the profit structure posed challenges to the organization. To solve these problems, members’ trust in the organization based on reciprocity was strengthened, and norms were created to sanction selfish behavior and promote participation. Additionally, network expansion led to expanded business areas. In the process, the organization has grown from a beneficiary of the service provided by the center to a subject of change.
