In the field of smart cities, there are several aspects that have not been considered in a collaborative manner thus far; such as urban planning and information technology, design and data analytics/simulation, urban management and social implementation. For the smart cities envisioned in the coming Society 5.0 era, there is an urgent need to develop human resources capable of utilizing their existing professional expertise in the realm of smart cities. Moreover, developing a network of professionals with diverse expertise to enable effective cooperation through adaptive collaboration depending on the situation is also crucial. This working group will build a programme to develop human resources and promote networking.
