Open data are characterized by a number of economic, technological, innovative and social benefits. They are seen as a significant contributor to the city's transformation into Smart City. This is all the more so when the society is on the border of Society 5.0, i.e., shift from the information society to a super smart society or society of imagination takes place. However, the question constantly asked by open data experts is, what are the key factors to be met and satisfied in order to achieve promised benefits? The current trend of openness suggests that the principle of openness should be followed not only by data but also research, education, software, standard, hardware etc., it should become a philosophy to be followed at different levels, in different domains. This should ensure greater transparency, eliminating inequalities, promoting, and achieving sustainable development goals. Therefore, many agendas now have openness as a prerequisite. This chapter deals with concepts of open (government) data and Society 5.0 pointing to their common objectives, providing some success stories of open data use in smart cities or transformation of cities towards smart cities, mapping them to the features of the Society 5.0. We believe that this trend develops a new form of society, which we refer to as "open data-driven society". It forms a bridge from Society 4.0 to Society 5.0. This Chapter attempts to identify the role of openness in promoting human-centric Smart Society, Smart city, and Smart Living.

翻译：开放数据具有经济、技术、创新和社会等多重效益，被视为推动城市向智慧城市转型的重要驱动力。当社会处于社会5.0转型期——即从信息社会向超智慧社会或想象型社会过渡时，这一作用尤为显著。然而，开放数据领域专家始终追问的问题是：要实现预期效益，需要满足哪些关键因素？当前开放化趋势表明，开放原则不仅应适用于数据，还应贯穿研究、教育、软件、标准、硬件等各个层面，成为各领域各层级遵循的哲学理念。这有助于提升透明度、消除不平等、促进并实现可持续发展目标。因此，众多议程已将开放作为前提条件。本章探讨开放（政府）数据与社会5.0的概念，揭示其共同目标，梳理智慧城市中开放数据应用的成功案例及城市智慧化转型路径，并将其与社会5.0特征进行映射。我们认为，这一趋势正在孕育一种新型社会形态，称之为"开放数据驱动型社会"——它构建了从社会4.0到社会5.0的过渡桥梁。本章旨在阐明开放化在推动以人为本的智慧社会、智慧城市与智慧生活建设中的核心作用。
