Abstract
Japanese society is facing a historical transition characterized by a declining population, a declining birth rate, and an aging society. This transformation process is unprecedented for humankind and has the potential to shake the foundations of Japan’s social economy and sustainability. Therefore, Japan needs to create a sustainable society. For instance, it is indispensable to achieve the desirable future society envisioned by the 17 sustainable development goals (SDGs); Sustainable development is based on the happiness and the well-being of the society. One solution is to create a society that can accept diverse work environments and lifestyles by embracing and cherishing the concepts of sustainability, happiness, and social well-being.
