The purpose of this paper is to discuss the role of a new style of planning for aged and environmentally conscious societies. The planning is based on the concept of taking advantage of community stocks and achieving solutions to community problems through co-creation involving various entities. This new planning consists of 5 elements; sharing community challenges and strategies, community empowerment, utilization of stocks as resources, project planning and implementation, and sustainability assessment. It seems important to promote new attempts by integrating these related elements and to clarify the necessary techniques and institutional issues for it.
