LABS FOR RAINWATER SOCIETY

 The objectives of this research are to propose the "rainwater society" city vision, develop methods for realizing this vision, and develop methods for popularizing and propagating this city vision.
 It primarily focused on the watershed of Hii River, which flows through Fukuoka City and has had multiple incidents of flooding in recent years, with a secondary focus on the watershed of Zenpukuji River, which flows through Tokyo's Suginami City.

 Planning technologies, design technologies, and elemental technologies can be used to achieve this corporate vision.

 In our research, we developed these technologies while maintaining a consistent focus on intergenerational co-creation of technologies that are alluring, cultural, and have potential for unseen future value.

 Furthermore, to spread the city vision of rainwater society, we positioned intergenerational co-creation as our fundamental methodology, and showed which perspectives are important for achieving this intergenerational co-creation. Intergenerational here refers to temporal intergenerationality, spatial intergenerationality, and generational intergenerationality. Temporal intergenerationality consists of the past, present, and future, creating a new future based on accrued history. Spatial intergenerationality extends across the spaces from the mountains to the seas. Generational intergenerationality refers to the young and old alike alive today. These various types of generations collaborate and cooperate in co-creation. Implementation is also an important methodology of this research. Implementation quantitatively demonstrates benefits to flood control, water utilization, and the environment.
 

 Numerous activities likely to resonate with these generations were prepared in this research with the aim of spreading this city vision. They were designed to extend, spreading from the core generations with which they most resonated to reach other generations as well.
