Abstract
Nine years have passed since the accident at the Fukushima Daiichi Nuclear Power Plant, but it is still difficult for residents to return to their homes in some municipalities. In addition, it takes 30 to 40 years to deal with the accident, which requires long-term efforts and decision-making across generations. In order to construct such a project for the reconstruction of Fukushima, co-creation project management by multigenerational and diverse actors is necessary. In this research, we analyze project continuity from the viewpoint of P2M, with the aim of realizing social innovation, which is a long-term strategy, through initiatives such as the Future Session at the Fukushima Study Group.
